BRAVE NEW WORLD For as long as construction equipment has had wheels and tracks, construction magazines have followed a tried and tested means of charting their development - words and photos, printed onto dead trees and posted to a waiting audience using snail mail. But while construction equipment has adopted remote monitoring, in-cab Bluetooth, low emission engines and a whole host of other technological advances, construction equipment magazines have remained rooted in the past and eschewing the Internet age. Until now. Diggers and Dozers has already proved that there is a global appetite for high quality video footage of construction plant and equipment in action. And now, we are bringing together the high editorial standards

Follow Us of the past with the high definition video of the future in an industry magazine like no other. Not only will we be telling you about the latest and greatest equipment in the plant sphere, we will show you that equipment in action in movie-quality 4K. It’s not quite the same as being there yourself…but it’s pretty close. As you will see, Diggers and Dozers is the next generation of construction equipment coverage.

Better Late Than Never

JCB might be the Jonnie-Come-Lately of the site dumper world. But dumper manufacturers dismiss its belated, badge-engineered arrival on the scene at their peril. Diggers and Dozers reports. There is no question that innovators can have a competitive advantage, reaping the rewards of their envelope-pushing, and leveraging their “first mover” advantage. But anyone that thinks that the “me too” manufacturers that follow in their wake are doomed to play catchup for all eternity need only look at the global domination of the seemingly ubiquitous iPhone. Smart phones and MP3 players had existed long before Steve Jobs and his Cupertino acolytes developed the first generation iPhone. And yet, within just a few short months, Apple was on track for global market leadership with a device that was part music player, part computer, part communications device and all status symbol. JCB’s arrival on the site dumper scene is unlikely to make quite as big a splash, based as it is on a badge engineering

agreement with Terex. But if history teaches us anything, it is that JCB does not do things by halves. And with a dumper range that is purposematched to its mini excavator and backhoe loader range, JCB has it in its power to catch and overtake the other manufacturers in the race for site dumper supremacy. Natural Evolution Perhaps the greatest surprise about JCB’s decision to enter the site dumper fray is that it seems so belated. The company threw its sizeable hat into the compact articulated dumptruck ring in the late 1980s. To move from that to the seemingly more simple and cab-less site dumper seemed – at the time – to be a natural evolution. It didn’t happen, even though the company had the requisite engine, gearbox and axle technology in place. Against that background, it seems strange that the company should wait a quarter of a century before offering a range of Terex-in-disguise site dumpers. Not so says JCB’s chief innovation and growth officer Tim Burnhope. “JCB builds a range of more than 350 machine models and

is the recognised market leader in many sectors,” he says. “By partnering with Terex and calling upon the pedigree of its dumper range, we can offer JCB customers a proven solution with a high degree of familiar JCB parts all sold and supported through the JCB dealer network.” Strength in Depth All told, the JCB site dumper range comprises 13 models from the one tonne payload 1T HT right up to the 10T FT. The smallest nine models in the range are powered by fieldproven and fuel efficient Kubota diesel engines that comply with EU Stage 3A emissions regulations. The largest model – the 10 tonne payload 10T FT – is powered by a Deutz TCD 3.6L4 turbocharged diesel engine developing 90kW and which satisfies EU Stage 3B and Tier 4 Interim emissions regs. Only the six tonne payload 6T FT (forward tip) and 6T ST (swivel tip) models feature a four cylinder JCB Dieselmax engine developing 55 kW and satisfying EU Stage IV and Tier 4 Final legislation. Travel speeds range from 11 km/hour on the hydrostatic one tonne models right up to 18 km/hour on the four forward/four reverse six, nine and ten tone units. Standard equipment includes folding ROPS frame, flashing beacon, adjustable seat and seat belt. All models are offered with JCB LiveLink remote monitoring support. There can be no question that JCB is late to the site dumper party or that it is arriving in a mature market with a product range that has been seen before and which offers very little in the way of true innovation. Nokia probably said much the same when Apple burst onto the mobile phone landscape in 2007. And where is Nokia now?

As part of the launch of the new range of site dumpers, Diggers and Dozers sat down with JCB’s chief innovation and growth officer Tim Burnhope to find out more about his company’s hopes and ambitions for the new models. D&D - So what will the JCB site dumper range comprise? Tim Burnhope - From the outset, JCB will offer a comprehensive range of site dumpers in the one to three tonne and the six to ten tonne payload class. We will also be offering a full range of standard, swivel and high tip models to suit the needs of our customers. D&D – Will the JCB models differ from the Terex models from which they are derived? Tim Burnhope – The JCB models will be very similar to the Terex dumpers, although the larger models will feature a JCB designed and manufactured powertrain that will be familiar to JCB customers. D&D – Why didn’t JCB just develop its own range of site dumpers? Tim Burnhope - JCB has a product range that comprises over 350 machine models. We recognised the need for a site dumper range to complement our backhoe loader and mini excavators. To bring them to market quickly, we decided to partner with a manufacturer with a proven pedigree. Most of the mini excavators we sell are partnered with a site dumper. Following the launch of our site dumper range, JCB customers can benefit from buying their mini excavators, backhoes and site dumpers from a single dealer source and for that dealer to be equipped to reliably support those machines with parts and aftersales service.

The Men Who Weld Tattoos A specialist fabrications company is rewriting the bucket hard-facing rulebook by pursuing an artistic and tribal aesthetic. Diggers and Dozers reports.

God created the Earth in six days.

On the seventh day, he rested. On the eighth day, having seen his football team lose at home and having awoken with a nearterminal hangover, he was in a foul mood so he devised the ultimate test for excavator buckets. And lo, he created demolition.

According to fabrications specialist Rich Holt, one of the key issues is that buckets are generally designed with digging in mind. They are manufactured to ease the flow of material in and out of the bucket with the minimum resistance. And that same lack of resistance tends to corral material – debris in the case of demolition – ensuring that the wear is contained and concentrated in the same place over and over again. The result is premature bucket wear and a hefty repair or replacement bill. “The front of the bucket is where all the wear and tear is contained as, basically, this is where it strikes the material,” Rich Holt says. “Over time, this will wear, causing the bucket to lose its strength and, ultimately, to fail.”

Bucket Kryptonite Demolition is to excavator buckets what kryptonite is to Superman. If there are two things in the world that excavator buckets hate most, it is impact and abrasion; demolition delivers both – quite literally – by the bucketful. Hidden rebar encased in jagged concrete grind, wear and eat away at buckets. And all the Hardox steel, ground engaging tools, reinforced teeth and cutting edges and enhanced operator care offers about as much long-term In the Worn Zone protection as a silk-line cloak afford Rich Holt, founder of Fabrications by Design, comes to buckets and a Matador.

demolition with a fresh pair of eyes. Relatively young, he openly admits that it was only a few short years ago that he thought that all excavators were called JCBs. Ad his first up-close encounter with a bucket was when he was offered the opportunity to actually work on one. But that fresh perspective also allows a fresh and innovative approach. And rather than replicate the straight line bucket protection that is the stuff of tradition and received wisdom, the bucket protection provided by Holt and his team is characterised by an intricate and unique tribal tattoo aesthetic that looks freshly ripped from the bicep of a hipster

with no imagination and hippy leanings. “What people used to do was weld rebar on or solid strips of hard facing wire.” Holt continues. “Our solution is basically putting hard facing wire down through a MIG welder, which is quick and cost effective. What’s really different with the way we do it is basically we heat the steel up, temp it, and then put the wire down in lots of different directions so it has more places to wear.” According to Holt, this approach is doubly effective. “By laying down the hard facing in these swirls and patterns, we are able to give the bucket greater protective coverage,” he explains. “In addition, the tattoo-style pattern helps to ensure that the material is dispersed and doesn’t follow the same path over and over again. This too helps reduce overall wear.” Rich Holt reports that, in addition to helping customers’ buckets last longer and reducing their owning and operating costs, there has been an unexpected benefit of his tattoo-style. “By the time a bucket leaves our premises, it is absolutely unique. Not only does this act as a deterrent against opportunist theft, it would also help trace the bucket’s original owner if one of our buckets was stolen.”

Dive, Dive,DIVE! A marine and civil engineering company has reconfirmed its environmental credentials with its use of a new zero tailswing Hyundai excavator. Diggers and Dozers It is not every construction site that has flippers and scuba tanks stored alongside the usual hard hats and high visibility vests. Then again, very few civil engineering companies can claim proudly that half its workforce are divers. But Kaymac Marine & Civil Engineering are not like most construction

companies. Founded in 1976, the Bristol-based company traded for a number of years, primarily supplying underwater engineering services for a limited client base. The company was bought out by the present management in the late 70â&#x20AC;&#x2122;s, and continued to

expand the client base with diving as the main core activity and applications including outfall pipeline inspection and repair, lock gate inspections, c o f f e r d a m installation and embankment stabilisation. The increasing demands from clients for work other than diving, mostly marine engineering above water, led the management to change the company name to Kaymac Diving and Marine Services, and the company continued to flourish under the new title. In 1994, a decision was made to enter into a new field; that of land based civil engineering.

This was as a direct result of experience gained in the marine engineering sector, which had proved a great success and had allowed continued expansion of the company and exposure to new clients outside the confines of the diving and underwater engineering sectors. The company name was changed once again to embrace all disciplines; and Kaymac Marine and Civil Engineering Ltd was launched in October 1994. Peace of Mind The company’s latest contract is at the site of Bristol’s former general hospital which is being turned into a series of waterfront

apartments. Kaymac’s works include the installation of storm drain outlets into the neighbouring harbour, core drilling through the harbour wall, and the installation of concrete limpet dams. While much of this highly specialised work will require the input of Kaymac’s diving team, the land-based operations have been charged to a new Hyundai Robex 145LCR-9A. This zero tailswing machine is responsible for excavation prior to the installation of manholes and manhole covers as well as a series of lifting duties around the site. “We chose the zero

tailswing machine because it just makes the site more relaxed. There is no fear of the rear of the machine over-swinging the tracks and hitting an obstacle or – worse – a worker,” says site manager Rhys Price. “The zero tailswing just gives us peace of mind and ensures that we can work in these relatively confined spaces safely.” Another key consideration, according to Price, was the environmental credentials of the new excavator. “Working alongside rivers and water courses means that we have to be ever mindful of the environmental impact of our equipment. We cannot afford oil leaks

and we keep a very close watch on engine emissions and fuel consumption,” Price continues. “The engine in the Hyundai is very quiet and very clean running and it satisfies Tier 4 Interim standards so it meets our exacting requirements and those of our clients.” Rhys Price reports that this is his first encounter with a Hyundai machine; and he is suitably impressed. “The Hyundai machine is quiet, comfortable and incredibly smooth to operate,” he concludes. “It has been a real bonus on this site and I would certainly recommend the Hyundai machine to other specialist contractors.”

Where Dirt Isn't Dirty Bristol-based Hydrock is fast establishing itself as a UK leader in the field of site remediation with a rapidly-expanding specialist plant fleet to match. Diggers and Dozers reports.

The UK Government’s desire to protect this green and pleasant land by minimising the amount of building that takes place on “green belt” land has given rise to an unprecedented growth in brownfield construction. While this is admirable and much appreciated by environmentalists and Range Rover-driving suburbanites alike, it has also spawned the rise and inexorable rise of companies that specialise in eradicating the legacy of our industrial past. These are the remediators; specialist companies that are equipped to replace contaminated soils with clean imported or cleaned in-situ materials that meet the exacting standards of the green lobby.

companies is Hydrock. Founded in 1995, the company has quickly established a national reputation for the quality of its remediation and preconstruction capabilities. Let’s face it, it is not every company still a few months shy of its 20th anniversary that can win the contract to handle any residual contamination at a former nuclear power station. Yet that is precisely what Hydrock achieved, winning the remediation works at the Hinkley B works in Somerset. The company, which operates from 13 office locations and employs around 250 people, is also involved in the remediation of a former coalfired power station ahead of the construction of a new Among the most successful campus for the University of of these relatively young Northampton. Known as the

Waterside Regeneration development, this contract involved the remediation of the former Nunn Mills Power Station and Avon Cosmetics Factory as an enabling works package for a ÂŁ330 million, 22 hectare, three-phase development project. Satisfying CLAIRE In the first phase of the Northampton project, Hydrock completed the work required on the power station site, and the current second phase is carrying out works on the former Avon Cosmetics manufacturing site. As well as remediation, this phase has included breaking up of the extensive concrete slab areas that formed the base and foundations of the former cosmetics factory, together with excavation, asbestos removal, removal of underground hard 28

structures and turning over of the made ground. Wherever possible, materials generated by the second phase works are screened and sorted for reuse on site, including the placement of engineered fill to form the development platforms. Overall, in preparation for later phases of works, Hydrock will remove 120,000 m3 of contaminated soils and other materials, and the import 30,000 m3 of fill material under the CL:AIRE Definition of Waste: Development Industry Code of Practice from a variety of other projects around the local area. This has brought additional sustainability benefits to the Waterside Project and sites which were otherwise sending the material to landfill. The University site has also posed ecological challenges for the Hydrock team, as seven rare

orchids have required relocation as well as the controlled opening, inspection and then sealing of a void suspected to contain bats. To tackle this challenging and environmentally sensitive contract, Hydrock has put in place an impressive array of plant and equipment including new crushing and screening equipment from Blue Machinery, a pair of Cat D6 dozers, several Prodem hammers to break out the foundations and floor

slab, and a wealth of new equipment from Doosan supplied by Kellands (Plant Sales) Ltd. “The Doosan equipment is of the highest quality and performing well for us. In particular, the latest generation of Doosan excavators has a strong and robust design, with sturdy undercarriages providing excellent stability for all the types of work we undertake,” says Hydrock’s senior site manager Graham Bean. “I have also found that the new Doosan machines

are faster than the excavators we have previously worked with.” Brand Loyalty That haul of Doosan kit comprises several new Doosan Stage IIIB compliant products including crawler excavators, a DA30 articulated dump truck (ADT) and a DL350-3 wheel loader. The DA30 ADT is powered by the Scania DC9 Stage IIIB (Tier IV Interim) compliant diesel engine with a gross power output of 276 kW. This is complemented by a high gross torque of 1,873 Nm at 1,300 rpm, to produce the powerful rim-pull required to work in extreme hauling conditions. The DX420LC-3 large crawler excavator is designed to handle a broad range of applications such as heavy earthmoving, road building, civil engineering, demolition, quarrying and large scale material-handling. The Doosan DL350-3 wheel loader, equipped with Stage IIIB-compliant Scania engine (5-cylinder

DC09 SCR engine delivering 202 kW at 1,800 rpm), has been designed and manufactured to provide maximum value. It offers excellent performance and productivity levels, combined with ease of use, simple maintenance and appreciable fuel savings. “We began purchasing our own plant in 2009, and we bought our first Doosan product, a DX300LC excavator, in 2010 for a project in Bath. Today, the majority of our fleet is made by Doosan and supported by Kellands,” explains Jacqueline Vargo, commercial manager at Hydrock. “The Doosan machines are competitively priced and the availability from stock is, in our experience, unmatched which is vital when you have a contract like this that just keeps getting bigger. Our in-house maintenance team takes care of much of the equipment maintenance, but the parts and aftersales support we receive from Kellands has been excellent; and that is a key reason behind our loyalty to the Doosan brand.”

LATER THAT NIGHT… BE PREPARED FOR ANYTHING!

When D Becomes E Staffordshire-based plant hirer JoinPoint switched out its 20+ strong fleet of D-Series Bell artics for their new E-Series replacements. Diggers and Dozers went to find out how the upgrade panned out. “The problem with some big equipment manufacturers is that they treat you like a number,” insists JoinPoint’s operations manager, David Brown. “Bell Equipment UK treat us like a long-time friend. That is the main reason why we stuck with them when we upgraded our entire articulated dumptruck fleet.” Brown reports that JoinPoint’s “friendship” with Bell stretches back more than 12 years to when the South African equipment manufacturer was viewed as something of Johnnie Come Lately in British ADT circles. A decade on and that relationship continues to go from strength to strength thank – in no small part – to the personal touch afforded by the team at Bell. “If we have any issues with the machines, parts or service, I can ring Bell’s managing director Nick Learoyd direct,” Brown explains. “With the other ADT manufacturers, I wouldn’t know who to call at dealer level, let alone at the manufacturer’s headquarters.” Fleeting Relationships But Brown knows there are no friends in business; and the company’s decision to invest more than £2 million upgrading its ADT fleet with the new B30E models was based on hard facts, not flimsy and potentially fleeting relationships. “We have always found the Bell ADTs to be tough, durable and reliable, which is vital in a plant hire environment setting where the machines might be working on a major muckshift one day and in a mine the next,” Brown says. “But with the arrival of the new E-Series models, that durability is complemented by excellent fuel economy, superb all-round visibility and lower operating costs.” The new E-Series haulers are powered by a Stage IV/Tier 4 final certified, 7.7 litre diesel engine delivering 246 kW of grunt via a fully-automatic, six speed planetary transmission with integral retarder. Engine power and fuel consumption are optimised through event dependant software that controls retardation, cooling and charging of accumulators. Brown explains that any equipment purchased by JoinPoint has to satisfy multiple masters. “As the equipment owner, we are looking for reliability, low operating costs and a good resale value. And based on our experience, the Bell machines offer the lowest cost per tonne on the market,” he asserts. “But any equipment that we buy also has to satisfy the needs of our customers and be well-accepted by the operators. Operator feedback suggests that the all-round visibility and ride comfort has been greatly improved. Our customers have always been happy with Bell technology, but we’re delighted that we are getting widespread praise for the new E-series machines.” According to Brown, there was never any question in JoinPoint’s mind about continuing to use Bell ADTs. “Bell and JoinPoint are both family-owned companies with an emphasis on exceptional service. Even though the Bell family is based in South Africa, it always ensures that the UK team shares those values,” David Brown concludes. “We have worked with Nick Learoyd and Bell Equipment UK’s sales manager Ian 32

The Heart of the Matter

Today’s

sophisticated construction, quarrying and recycling machines have powerful hydraulic systems at their heart. As with a human it’s vital to keep the system in a healthy condition to maximise performance and reliability. In the same way that your doctor would check your temperature, blood pressure and carry out a blood test if you were ‘under the weather’ you can carry out a machine ‘health check’ with a few relatively simple tools. Hydraulic oil can be considered as the equivalent of blood in a human, its condition affects machine performance and reliability. Essential Tasks Hydraulic oil performs several essential tasks in modern construction equipment. Firstly, it provides fluid power, transferring the energy from the machine’s engine to the hydraulic components to operate the machine. In an excavator the engine driven pump provides a flow of hydraulic oil under pressure that is used operate the track motors, the slew motor, and hydraulic rams to operate

the machine’s boom, dipper, and bucket. Secondly, it provides the required lubrication between component parts minimising wear. Thirdly, it provides a heat transfer function spreading heat throughout the system and providing the means to cool the system through the use of oil coolers. Hydraulic systems, in modern machines, operate at very high pressure, up to 450 bar, and under extremely close tolerances 38

The hydraulic system is the beating heart of all construction equipment. Keeping that heart healthy is key to ensuring that equipment has a long and productive life. Diggers and Dozers reports.

demanding regular monitoring of fluid cleanliness. Particle and water contamination are the most common hydraulic system problems both of which lead to increased wear and potential damage to the fine tolerances of pumps, valves, motors and cylinders.

Essentially there are four tests that can be carried out to monitor the condition and performance of hydraulic oil and hence machine health. 1. Oil temperature 2. Oil pressure 3. Oil flow rate 4. Oil contamination, water and particulates If you suspect that a machine has lost performance and need to troubleshoot the hydraulic system there are a wide range of tools to help from simple analogue pressure gauges through digital pressure gauges to sophisticated flow turbines and digital data loggers. Temperature Measurement Most modern machines are equipped with monitoring and diagnostic tools that are integrated into the machineâ&#x20AC;&#x2122;s engine management and hydraulic systems. High oil temperature is usually a sign of either low coolant or oil levels or blocked radiators or oil coolers. If all these are OK but oil temperature is too high there are several tools that can be used to accurately measure hydraulic oil temperature under different operating conditions. Very accurate temperature sensors, with a working range from -50Â°C to 200Â°C, can be fixed in Minimess test points which can be fitted in any run of hose or pipe using standard hydraulic adaptors with the appropriate thread for the machine. (E.g. BSP for a JCB, JIC for Cat, Metric for continental European machines). An electronic data logger is used to read the electronic signal from the temperature sensor and convert it into meaningful data that can be recorded and analysed as part of the fault finding process. 41

Analogue Flow Measurement A universal truth is that when troubleshooting hydraulic systems flow should be checked first followed by hydraulic pressure in a specified order of priority through different points of the system. The simplest way to accurately measure hydraulic flow is to mount a flowmeter into the hydraulic system at an appropriate point. Instruments like the Hydrapro 702 cost around £780 (including VAT) but make flow measurement a safe and practical proposition. The instrument has a stainless steel body, ¾ inch BSP ports and can work safely at up to 240 bar. It is an analogue instrument, which is nonelectrical, making it both reliable and durable. It can be easily fitted into a run of hose or pipe using adaptors. Once installed the Hydrapro shows hydraulic flow up to 110 litres per minute, temperature to 116°C, and pressure up to 345 bar, adequate for even large excavators. An integral load valve allows the system to be put under load up to 414 bar, simulating a work cycle. The Hydrapro can also be used for setting-up a pipework kit and system for dipper mounted breakers and other hydraulic attachments. Analogue Pressure Management Checking hydraulic pressure in a hose run is comparably simple and relatively cheap (£120) analogue pressure test kits are good enough for a quick check. They are mounted into the hydraulic system using adaptors with the appropriate thread form for the machine. Analogue gauges show pressure but do not record data and they are not capable of showing pressure spikes for example. Digital Pressure Management The next step in sophistication is to use a digital pressure gauge or kit. The advantages, over analogue gauges, are that they are much easier to read, they are more accurate 42

A flow turbine unit RE4 is mounted securely in the hydraulic system using adaptors at a hose or pipe joint. The turbine unit measures flow, temperature and pressure and transmits digital data to the data logger in 3 channels. The unit provides a ‘real-time’ read out of the parameters being measured and records the data in the internal memory. The data is easily transferred to a PC via a standard USB port.

D&D Insight

Pressure test points practical steps. • Many machines will already have pressure test points mounted on pumps or in the hydraulic circuit. • It is safe and easy to fit pressure test points in a machine’s hydraulic circuit. The machine should have the engine off and hydraulic pressure in the system should be dissipated by operating the control levers. • Pressure test points can be fitted for temporary use or as a permanent fixture. As long as they do not constrain the circuit’s hydraulic flow they do no harm. • An adaptor and pressure test point can be placed at any hose or pipe junction. • The hose/pipe joint is opened and the ‘T’ piece adaptor screwed into place. Adaptors are readily available in all the common thread forms including BSP, JIC, ORFS and metric. • The ‘T’ piece is fitted with a Minimess pressure test point. Minimess test points provide a safe interface to the active hydraulic circuit. • An analogue or digital pressure gauge is easily fitted to the Minimess test point using a gauge adaptor. • Low cost pressure test kits provide all the components required. • Minimess test points can also be used for taking oil samples.

Much to Smile About The CEO of the Construction Equipment Association is in ebullient mood; and with good reason. Diggers and Dozers reports. reports.

CLICK THE BUTTON by the picture and watch the video Rob Oliver, the chief executive of the Construction Equipment Association (CEA), has much to smile about. Stand space at the PlantworX exhibition is selling like the proverbial hotcakes; his beloved West Ham United sit in a lofty position near the top of the Premier league table having (at the time of writing) just scared the bejabbers out of the recently deposed kings of world football, Manchester United. More importantly, the membership of the CEA – the elite manufacturers from the plant sector – has shaken off the recessionary shackles and is now basking in the knowledge that the UK construction equipment sector is currently outperforming virtually every other national plant marketplace. “We are very pleased with the renewed strength of the UK market. Demand is up and there is a good forward pipeline for equipment of all kinds,” Rob Oliver states. “But we must remember that around 70 percent of all construction equipment produced in the UK is destined for export markets where the picture is not quite so rosy. North America remains strong and we are planning trade missions to South America where things are looking very positive. Closer to home, however, it is a different story. France is taking a long while to recover, and much of Southern Europe is still in the doldrums. And India, a region which holds so much promise, is still probably a year or two away from fulfilling that promise.” Skills to Pay the Bills Despite these economic uncertainties across the globe, Oliver remains upbeat. He cites the UK’s leadership in the development on equipment monitoring and control systems as a key area for pride. “The CEA works very closely with manufacturers and suppliers of state-of-the-art electronics and these companies are achieving things now that would have been unthinkable just 10 years ago,” he insists. “There has been a lot of talk about driverless machines, and not just in mining applications. And UK companies will be at the very forefront of that development.” While some member companies are focused on removing the human element from the construction plant world, the CEA is focused on addressing the impending skills shortage within the construction, construction equipment and engineering sectors. “A recent survey highlighted the fact that around 70 percent of our members had issues in the recruitment and upskilling of staff,” Oliver explains. “The construction industry as a whole needs to attract several hundred thousand new workers to satisfy demand. And as machines 46

grow increasingly sophisticated, upskilling of existing workers will become a priority.” To help address this growing challenge, the CEA has formed its own skills advisory panel to work with industry to create a strategy to engage with education and higher education. Furthermore, the final day of the association’s PlantworX 2015 exhibition will be “Student Day”. Students and teachers from primary and secondary schools and colleges are invited to attend the show (after 12pm on Thursday 4th June) to get a taste of the construction equipment sector. There will be no lower age limit after 12pm and the afternoon is aimed at encouraging youngsters to look at the construction equipment sector as a career. Perfect Timing According to Rob Oliver, the timing of this industry recruitment drive could not be better. “For the past 15 years or so, much of the technological advances made in this industry have been focused upon reducing engine emissions and maximising fuel economy,” he asserts. “But we are now entering a phase in which more and more of the research and development spend will be focused upon delivering what customers need rather than what legislators and environmentalists demand. It will be a hugely exciting time for young people to join a cutting edge industry and to demonstrate their own problem-solving and solutionsproviding capabilities.”

Sometimes, They Come Back Buckets lie open, mouths agape, teeth chipped, crooked or missing like the doom-laden, spittlespecked maw of an evil crone. Headlights that once shone brightly now stare sightlessly into the gathering gloom, cataracts of time and dirt rendering them forever blind. Tracks that once hauled these proud machines into daily battle now frozen, seized rigid like arthritic fingers. And the names writ large upon these hulking relics of a bygone age – names that were once badges of pride and prestige – now serve merely as weedstrewn grave markers for machines that have run their course; and for their makers who failed to keep pace with the industry’s insatiable appetite for innovation and were left – Neanderthal-like – on the evolutionary hard shoulder. This then is the part of the SE Davis & Sons plant yard where tried and trusted plant is put out to pasture; a care home-cum-cemetery for equipment that will never again turn a track or 50

a wheel; machines whose race in long since run; machines that can only sit idly by as younger, faster, cleaner and more productive equipment purrs mockingly by on its way to work.

At first glance, it looks like the plant equivalent of the elephant’s graveyard; a place where equipment goes to die. But something stirs amidst the rotting corpses of these long-forgotten machines. Mark Anthony reports.

The Undead Yet for all its appearances as the plant world’s approximation of the apocryphal elephant’s graveyard, not everything here is dead. Some return as loyal standby or stand-in replacements for younger, fitter models – Like Ronnie Wood playing guitar with One Direction. Others are forced to endure the ignominy of being part of a Dr Frankenstein abomination, bolted and welded together with bits of other machines to fashion something hideous to behold and yet serviceable. Worst of all are the machines that are destined to spend all eternity as living organ donors; cannibalised; their parts torn from their aged bodies to make do and mend a younger machine. And yet, for all the decay, there is one factor that stands out like the proverbial sore thumb. “When you chart the history of construction equipment, you quickly realise that nothing is actually new,” insists

lorem ipsum dolor sit amet 51

Paul Davis. “The newer machines might be shinier, more fuel efficient and more productive, but the heart of the design of a machine like a dozer or a tracked shovel has remained largely unchanged in the past 50 or 60 years.” SE Davis & Sons was founded in 1930 initially as a farming company specialising in poultry. At the height of its chicken-related activities, the company had 65,000 birds. But Paul Davis’ grandfather Bob had developed a taste for heavy equipment. And this was to shape and track the company’s development during the following half century or more. “You can trace the company’s history and diversification by the machines we owned and operated. We started out with Ferguson tractors for farming duties, moving into tractor/balers. When we started working within the demolition business, we acquired several tracked shovels. In 1970, we were approached by Komatsu – then a relative newcomer to the UK construction business – to store some of their machines prior to sale. By 1973, that stock had an insurance value of £9.0 million,” David recalls. “That development is also visible in our vintage machine collection of almost 600 machines. We have dozers and tracked shovels from Caterpillar, Allis Chalmers’ machines, several Ruston Bucyrus crawler cranes and then on into Komatsu machines from the 1970s.” Museum Piece All of these machines – together with an equally impressive collection of steam engines – will soon be brought in out of the cold. Paul Davis reports that the company has been granted

planning permission to turn its impressive vintage plant collection into a museum with all of the machines under cover. Furthermore, the display will include a restoration and training area where machines will be brought back to their former glory, and viewers can participate in bringing the machines back to life. The SE Davis yard â&#x20AC;&#x201C; a proud monument to some of the greatest machines to ever have moved earth â&#x20AC;&#x201C; lies close to a main road and is surrounded on three sides by houses.

And yet when the working day is over and the ceaseless toing and froing of a modern plant hire operation stops for the night, an eerie silence falls upon the yard like a damp, musty funeral shroud. The air grows strangely cold, carrying with it the acrid stench of diesel coagulated and congealed by decades of quiescence. But, if you listen closely, you can still hear the low, guttural growl of an ancient engine, the squeal of primitive tracks on concrete like ragged fingernails down a blackboard, the menacing serpentine hiss of hydraulic oil passing through arteries thinned by the passage of time. And sometimes â&#x20AC;&#x201C; just sometimes â&#x20AC;&#x201C; they come back.

A great business decision.

ye Demolition has invested in a number of new Hyundai excavators paired with Prodem attachments. Itâ&#x20AC;&#x2122;s a winning combination, as Diggers and Dozers reports.

Down in darkest Silvertown – which always sounds like it belongs in the Wild West at the height of the gold rush rather than the North bank of the River Thames – a demolition company is achieving what Germany’s Luftwaffe failed to do during the height of the Blitz. It is destroying part of the Royal Wharf. Located directly opposite the ExCel exhibition centre, Royal Wharf covers an area of around 25 hectares, making it the single largest property development to come to market since Battersea Power Station scheme was given the green light. Property developer Oxley Holdings plans to build almost 4,000 new homes on the site to take advantage of the nearby Crossrail station which will provide a fast, eight-minute link to London’s Zone 1. Before then, however, there is the small matter of demolishing the tough and over-engineered remnants of the docks’ industrial past. “The docks were basically built to be bombproof,” explains Rye Demolition’s Ashley Barlow. “The concrete here is three metres thick in places, heavily reinforced, and really tough to break. We have had to bring out the big guns for this.” Eating Concrete

CLICK THE BUTTON by the picture and watch the video

Those big guns comprise a Hyundai 380LC-9A newly delivered by local dealer Molson Group. The ammunition is provided by a Prodem PRB400 hydraulic breaker, a 3.1 tonne hammer supplied by West Sussex-based BPH Construction Equipment. “Despite the hardness and thickness of the concrete here, the Prodem hammer is performing really well,” Barlow continues. “This thing just eats reinforced concrete.” Barlow reports that Rye Demolition’s relationship with BPH has prospered over the past few years. As a result, the fast-growing demolition firm now has an equipment fleet that includes hammers, munchers and shears in the familiar BPH livery. According to Barlow, this owes much to the aftersales support provided by BPH. “We take good care of all our equipment. But demolition is a tough business and attachments take the brunt

of the impact and wear damage, so it is vital that parts and aftersales support is fast and reliable,” he says. “If we break a hammer chisel, BPH will have a replacement on site within 24 hours, guaranteed.” Perfect Partners According to Ashley Barlow, the partnership with BPH has been key to the steady growth of Rye Demolition in the recent, post-recession years. “We are fortunate to have landed some prestigious contracts with some very large clients and we have slowly built a reputation for the safety and efficiency of our work,” he says. “But to do that, we need the right equipment; equipment that is safe, productive and reliable. And that’s what we get from BPH. Our reputation is based on our ability to deliver difficult and tough demolition jobs on time and on budget. We couldn’t do that without the support that BPH provides.”

At TXM Plant we go above and beyond to provide exceptional rail solutions and care for our clients. We strive to innovate and inspire the rail industry by leading the way in technological & plant ingenuity, all the while maintaining exceptionally high standards in health, safety & environmental practices.

ackhoe irthday

30 years after it took the wraps off its first backhoe loaders, Caterpillar has announced the introduction of its new F2-Series range of machinesâ&#x20AC;&#x201D;427F2, 428F2, 432F2, 434F2, and 444F2. The new models feature an all-new operatorâ&#x20AC;&#x2122;s environment, and engine technology enhances machine performance and saves fuel.

The cab has been restyled for a more modern look and has been designed throughout with the operator in mind, including enhanced visibility to the loader attachment when at full height and reduced in-cab sound levels, to 74 dBA. Machine-control ergonomics have been improved with a new telescopic/tilt steering column, and the differential-lock control has been repositioned to the loader controller. Pilot-operated machines feature new multi-positional excavator controls that enable operators to adjust to the most comfortable operating position, reducing fatigue. A forward/reverse controller is built into the loader controller for added convenience. The cab features a new step design with reduced height for added cab access/egress safety and a bottom step that is resiliently mounted to prevent damage from debris. The new cab is designed to allow operators to turn easily between loader and excavating positions, and an air-suspension seat provides all-day comfort, especially when using the optional heated version in cold weather. A new LCD display provides information needed to monitor machine performance, new switches feature improved back lighting for easy use in all ambient-light conditions, and longer-life LED rear lights are now used. The new pantograph front-

screen wiper increases the swept area for enhanced forward visibility and is complemented with a full-width, perforated sun visor. Except for the curved front window, all other glass areas are flat, enabling quick, low-cost replacement. Connectivity is a vital requirement for today’s machine operator, and the F2-Series provides an available radio with blue-tooth connectivity, facilitating communication with job-site personnel. A new keypad security system provides added protection for the machine, and a choice of cellular or satellite technology is available for use with the ProductLink™ telematics system for tracking machine location and operating parameters. The new 428F2, 432F2, 434F2, and 444F2, use the Cat C4.4 ACERT™ engine with a selective catalytic reduction (SCR) exhaust after-treatment system. SCR is a proven, reliable, widely accepted technology for controlling nitrogen-oxide (NOx) emissions by allowing exhaust to react with diesel exhaust fluid (DEF—a specific mix of urea and water) in the presence of a catalyst. No operator intervention is required to support the SCR system other than replenishing the DEF tank. If low fuel consumption is important, the operator can elect ECO mode, enabling proficient performance and controllability at a fuel-saving lower engine speed. Depending on the model, engine-power choices include 70 kW, 74.5 kW, or 82 kW configurations. For added convenience, a remote jump-start system is standard equipment. New to the Cat backhoe loader range is the 427F2, powered by a 55-kW (74.9-hp) Cat C3.4B engine that requires no SCR after-treatment and meets Stage IIIB emission standards with only a diesel particulate filter. The 427F2 can be fitted with an optional 6F/3R Autoshift transmission with a lockup torque converter that provides efficient road speeds. The 427F2 combines excellent all-round performance and up to 10 percent lower fuel consumption than the 428F2, making the new models a viable choice smaller contractors and rental businesses. The 428F2 and 434F2 also feature increased hydraulic flow for optimum hydraulic performance.

Avant Warranty Boost

Compact, multi-purpose wheeled loader specialist Avant Tecno (UK) of Thetford in Norfolk has announced a major change to its standard warranty and service schedule interval policies. With effect from 2015, all machines manufactured after January 1 will carry a two, rather than one year warranty - only restricted by the number of hours worked. For example, the larger R, 5, 6 and 700 Series machines will all have a generous 1,000 hour limit before the warranty expires. For this new warranty to remain valid for the full two years, Avant insists that every machine has a full, documented service history from an approved dealer which must also only use genuine parts. In addition, the company is doubling the service intervals for its R, 5, 6 and 700 Series models from 2015 onwards from 200 to 400 hours, with a first service at 50 hours as before. Commenting on the changes, Avantâ&#x20AC;&#x2122;s UK managing director Raimo Ala-Korpi said: â&#x20AC;&#x153;We have been able to introduce these improved warranty and service interval policies thanks to a continuous programme of development in terms of both build and component quality. For example, we now use highly reliable piston drive motors on all our larger models.â&#x20AC;?

Doosan to Dig Deep

T Dash 5 Doosan excavators head for Paris launch pad. At Intermat 2015, Doosan will be showing the new 36 tonne DX340LC-5 and 40 tonne DX380LC-5 Stage IV compliant crawler excavators for the first time, providing significantly improved performance compared to the previous ‘LC-3’ Stage IIIB models. Featuring a distinctive new machine styling scheme, the ‘LC-5’ range improves the already high standards set by the previous LC-3 range, adding to enhanced comfort and controllability with new features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, robustness and agility. The operating weights of the DX340LC-5 and DX380LC-5 have increased by 1,300 and 1,000 kg, respectively, and with the heavier tonnages, lifting capacities have increased by one and five percent over the front and side in the DX68

340LC-5 and three percent over both the front and side in the DX380LC-5. The new DX340LC-5 and DX380LC-5 are powered by the Scania DC9 5-cylinder diesel engine that develops 237 kW at 1,800 rpm. The engine meets Stage IV emission regulations without the need of a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies. Among the exclusive features of the Scania engines are the dual fuel filter and water separator systems. In the first, a full-flow paper fuel filter is used to remove large particles with a centrifugal cleaner filtering out small particles, providing operating economy and lower environmental impact. The water separator utilises a 10 micron sized primary filter connected directly to the fuel tank, and a three micron sized pressure-type secondary filter. The filters are equipped with a heating function as standard for better cold crank performance. Both the DX340LC-5 and DX380LC-5 feature the innovative Ecopower hydraulic system, which consists of a closed-centre main control valve (MCV) and a pressure-controlled pump. The system functions through the EPOS controller which receives joystick and pedal signals via pressure sensors and main pump flow rate through swivel angle sensors. According to the operator’s inputs, the EPOS controller outputs the requirements to the EPPRVs (Electro-Proportional Pressure Reducing Valve) for the pumps to generate the required flow. This new electric control of the pump power, combined with the closed-centre MCV, uses the engine’s power more effectively – maximising pump usage and reducing loss of flow and pressure – which results in more powerful performance in combined movements as well as more comfort, smoothness and accuracy. As a result, the DX340LC-5 and DX380LC-5 have two pumps as

standard, allowing attachments to use both pumps for increased flow. The second pump always works at full flow. This system is necessary for certain applications (e.g. demolition) to supply the power required to operate attachments such as crushers and shears. The DX340LC-5 and DX380LC-5 are factory-installed with the new CoreTMS state-of-theart wireless fleet monitoring system, a feature not previously available as standard on Doosan excavators and now incorporated in all new LC-5 generation machines above 14 tonne. The new CoreTMS system is a tool designed specifically for the Doosan range, providing

comprehensive information about machine performance in a dual mode (satellite, GSM). Because the software in the CoreTMS system has been upgraded to communicate directly with the EPOS system on a Doosan excavator, it is the only tool of its type capable of providing this level of information, delivering insightful and cost-saving data about equipment to help customers work more effectively. Also available for retro-fitting in a kit form, the CoreTMS system is supplied with a free 3-year subscription in new LC-5 excavators and customers are provided with their own account so that they can manage the machines in their fleet using the system.

SKIDSTEER GOES TO POOLE ANY PORT IN A STORM

For use in the Port of Poole in Dorset, England, Poole Harbour Commissioners (PHC) has purchased a new Bobcat S630 skid-steer loader from Kellands (Plant Sales) Ltd. With an area of approximately 36 km2 and with the town of Poole on its shores, Poole Harbour is claimed to be the largest natural harbour in Europe. PHC is the sole employer of the skilled stevedores at the port and offers a full range of freight and passenger ferry and cargo handling operations. Sharing the navigation channels with sightseeing vessels and leisure craft of all types are crossChannel freight and passenger roll-on/roll-off ferries along with conventional bulk cargo vessels utilising the port. Against strong competition for continental traffic between the south coast ports, PHC has maintained Poole as a prosperous, medium-sized port well in tune with its harbour environment. â&#x20AC;&#x153;We have been using Bobcat skid-steer loaders for many years and we have always found them 70

to be very suitable for the work in the port, offering unmatched reliability throughout their years of service,” says Paul Gillingham, Engineering Manager at PHC. “This is exemplified by our existing Bobcat 863 loader which we’ve been running trouble-free since its purchase in 1999.” Among a variety of applications around the port, the new Bobcat loader is used principally to help in stockpiling materials such as sand and clay delivered by truck to the quayside, so that they can be loaded into ships’ holds by the port’s grab cranes. As more and more material is removed from the piles, that remaining becomes too dispersed for the grabs to be effective and it is at this point that the Bobcat loader takes over. Equipped with an optional front door, the new Bobcat S630 skid-steer loader is used

ROLLER ALLIANCE

THE WAY WE ROLL

Wacker Neuson SE and the Wirtgen Group have agreed to enter a strategic alliance for soil and asphalt compaction rollers. Starting in February 2015, Wacker Neuson will source rollers from the Hamm factory in Tirschenreuth, Germany, and distribute them via its own sales network, focusing initially on markets in Germany, Austria and Switzerland. Hamm AG is a member of the Wirtgen Group and has been producing rollers for over 100 hundred years. The company’s portfolio includes compactors, tandem rollers and static rollers. From 2015 on, the factory in Tirschenreuth will be producing models to the technical and design specifications of Wacker Neuson. “This long-term collaboration brings together two strong players in the compaction sector that complement each other perfectly,” explains Cem Peksaglam, CEO of Wacker Neuson SE. “The alliance with Hamm 72

to form new mounds of material on the quay which can then be lifted off the quay by the grab cranes. Similarly, the Port of Poole uses the existing Bobcat 863 loader for ship-trimming applications in ship holds, where it again works in conjunction with crane-mounted grabs on the quayside to unload ships carrying bulk cargoes such as grain and animal feed. The grab begins the process of unloading the ships by taking as much cargo as it can and loading it into trucks on the quayside. As more and more cargo is removed, that remaining again becomes too dispersed for the grab to be effective and at this point the Bobcat 863 loader is lifted into the hold to do a similar job to that performed by the S630 loader.

will enable us to close gaps in the Wacker Neuson product portfolio and round off our offering in the soil and asphalt compaction segment with tandem rollers weighing from 1.8 to 4.5 tons, plus compactors weighing up to 7 tons.” The rollers produced by Hamm will be distributed via the Wacker Neuson sales network under the Wacker Neuson brand. The Group will initially focus on markets in Germany, Austria and Switzerland, expanding to global distribution further down the line. “We have excellent market penetration and a particularly dense sales and service network in German-speaking countries,” concludes Peksaglam. “The additional roller models from Tirschenreuth will enable us to offer customers an even broader and deeper portfolio of compaction machines backed by our proven, customer-centric service

Lawson Cracks Cat Code Demolition specialist Lawson Group has invested in a new fleet of Cat machines from Finning, that have already been put to work on demolishing and remediating the old GCHQ in Cheltenham for a major house building development. The new fleet deal consists of a Cat 374DL, two Cat 336EL’s, a MP30 work tool and the Finning Finsight equipment monitoring service. In addition to the new equipment, the business has also opted for a complete engine change out for its existing Cat 365CL excavator. The new and refurbished machines are joined onsite by two Cat 323DL excavators and a Cat 962H wheel loader. Purchased specifically for the GCHQ job, the lead Cat 374DL excavator, complete with a 3.8 cubic metre heavily modified bucket, is being used to rip apart the vast network of reinforced concrete tunnels and data cabling. “This is a particularly challenging project, as it was not the above ground buildings we had to worry about, it was what awaited us below the ground. This is why we opted to add the Cat 374DL to our fleet, as we required a really powerful piece of equipment to cope with this and additional secured work,” says Lawson Group MD Martin Wilson. “With our new additions, we have now grown our Caterpillar fleet to 14 units, strengthening our capabilities to offer customers not just demolition services, but complete site remediation, including material re-handling and recycling. We now have an 11 year ongoing relationship with Finning and Caterpillar and with sustainability now so important in our industry, it is vital that our suppliers become an integral part of our business.”
