Teeth for the most extreme conditions

Duracore – composite teeth for dredging ®

Combi Wear Parts has collaborated closely with Sandvik Hard Materials to develop Duracore®, a teeth series with extra long life designed for dredging.

Duracore® features a rod made from tungsten carbide, an extremely hard material, that is casted into the tooth. This gives the tooth up to five times longer length of life than ordinary teeth.

C o m b i w e a r pa rt s m a g a z i n e

Sandvik manufactures the rod in a material specially developed and tested for Combi Wear Parts. Production of the tooth itself and the fitting of the rod in the tooth are carried out at the Combi Wear Parts foundry in Ljungby. Duracore® is patented in 30 countries and is protected by two patents.

Today, Combi Wear Parts is in principle the only company in the world that successfully produces and sells composite teeth with such exceptional wear strength.

More benefits with Duracore® There are many benefits from using Duracore® during dredging. For example, Duracore® has much higher penetration and an increased life length. This means much lower material costs as well as quicker production because the teeth do not have to be changed so often. The obvious conclusion is that using Duracore® is much more cost-effective than using normal teeth without a hard-metal core.

After switching to Duracore® tooth consumption fell to around 220 teeth every day, which naturally meant a huge cost saving,” continues Per. “Thanks to Duracore® there were also considerably fewer production stoppages because the Duracore® tooth lasts around 2.5 hours instead of just 35 minutes for a standard tooth.

Switching to Duracore® gave a double benefit in other words,” concludes Per Quarfordt, holding the rod made of tungsten that enables this fantastic cost saving.

Used all over the world Duracore® is used at dredging sites all over the world, including the Panama Canal, Qatar, Australia and the Bahamas.

“One example where this was clearly shown recently was the dredging operation in the port of Ras Laffan, Qatar,” says Per Quarfordt, Product Manager Dredging at the Combi Wear Parts head office in Kristinehamn. “Before the dredging company began using Duracore® they used an incredible 1,000 teeth per day during a busy period. Each tooth weighed 22 kg so that meant several thousand tons of material worn out every day, which was costing the company large sums.

Teeth from Combi Wear Parts

dredging Teeth from Combi Wear Parts are used for dredging operations all over the world, from Australia to South America, and also here in Scandinavia.

One example is the Öresund bridge between Sweden and Denmark.

When the tunnel below the bridge, which runs for 4,050 metres, was built, enough soil was dredged to form a whole new island, Pepparholmen. This artificial island acts as a transition area between the bridge and tunnel.

Dredged material is pumped into barges.

can dredge in waters up to 35 metres deep and with the help of winches dredge across a width of 50 metres. A crew of 43 people keep D’Artagnan in optimum working order.

In ideal conditions she can dredge up to 2,000 m3 material per hour.

That would fill 200 truck loads an hour. Now, trucks aren’t used to remove dredged material, of course.

Barges that moor alongside the dredger remove the material or it can be removed using pipelines.

Double capacity soon

New production plant in Ljungby Next year will see the inauguration of a new production plant in Ljungby. Keycast Group, a Scandinavian foundry business, is investing in completely new production technology. The construction has already started.

“In order for us to compete successfully on international markets, each part of our business must be fully optimised,” says Fredrik Ivansson, President of Keycast Group.

More than just a foundry Keycast and its subsidiary Combi Wear Parts have operated foundry production in Ljungby, southern Sweden, for many years. The company is now expanding its

presence in the area by building a new, state-of-the-art foundry. And that’s not all. “Alongside construction of the new production plant, our subsidiary is also investing in two new melting furnaces for the existing foundry,” says Fredrik Ivansson.

Mining industry highly important “No-one can see into the future, of course, but we expect the mining industry to expand significantly,” says Fredrik Ivansson. “Thanks to this upgrade of our capacity we will be much better equipped to match market peaks and customers’ increased demands.”

Doubled capacity The result of the investment will be a doubling of capacity and a significant increase in both efficiency and flexibility, which is vital in a highly competitive business.

“We bring new opportunities and add a new dimension to the group.

Now all of our member companies can develop business with both existing and new customers. We have sharpened our elite expertise while we are also extending the general breadth of our business offer. We will be modernising the foundry business, which means greater opportunity for innovation using the latest technology. This will benefit everyone,” says Fredrik Ivansson.

Bauma 2013 First of all we would like to thank all visitors, customers and new contacts who visited our stand. This year’s Bauma exhibition was massive. Around 530,000 people from over 200 countries visited 3,420 exhibitors from 57 countries.

The size of this year’s exhibition – 8

570,000 square metres – was a record, and both numbers of visitors and exhibitors were also records.

Combi Wear Parts met a lot of very interesting visitors at the exhibition.

Our Combi Wear Party on 17 April was a great success. In addition to

spending some enjoyable time together relaxing we were also able to welcome two newcomers in our distributor network – Rotator in Finland and DemGroup in Belgium, both of whom are Hitachi machine retailers.

Primary and secondary Caves are normally divided into two sorts, primary and secondary caves.

Primary caves are formed together with the surrounding material. One example of this is a lava cave, which forms when lava running down a mountain solidifies on the surface, but lava further down carries on running, so when the inner lava disappears, a hole remains.

Digging isn’t the only way that holes are made in the ground. A cave is a natural hole. A cave is usually defined as a space large enough for a human to enter. That person might just be a speleologist. Speleology, or the study of caves, derives from the Greek word for cave or

Interview with:

gerhard henle We met up with Gerhard Henle, the owner and CEO of Henle Baumaschinentechnik GmbH in Rammingen, south-west Germany, about 70 km west of Munich. Gerhard Henle started his business back in 1982 and formed a limited company in 1999. Today he has around 50 employees and most of his customers are in Germany, although he does do international business too.

Henle Baumaschinentechnik GmbH manufactures and repairs accessories for construction machines, with a focus on medium sized and smaller excavators. The company is also the retailer for Combi Wear Parts products in southern Germany.

We asked Gerhard Henle about the future of his company: “Our new production building has very new and top modern equipment so this will strengthen our business enormously and give us new opportunities for future growth.

We are concentrating hard to expand our market shares both in Germany and abroad. We are also developing new product groups so we can expand in new markets.”

What does Gerhard Henle think about working with Combi Wear Parts?

“They have been with us ever since we started in 1982 and we appreciate this collaboration a great deal.

One of the best things about Combi Wear Parts is that they are so flexible and easy to cooperate with.

Their service level is excellent. I must also say that thanks to the very high quality of their products they have helped us establish a very good reputation on the market. They are exceptional when it comes to solving general problems and finding the best solution for all the situations a customer may face.

Quite simply, they are always willing to help.”

Team work solved the problem

Henle Baumaschinentechnik GmbH was given a special assignment that presented a great challenge for Gerhard Henle, owner and CEO of the company, and his experienced team of repair staff.

The job involved repair and reinforcement of a deep bucket for an 80-tonne ecavator. This particular machine was used for extreme demolition tasks that set the toughest requirement on both machine and equipment, including teeth and adapters.

12

Broken teeth cause damage

Toughest specification

The teeth previously used had broken repeatedly due to the massive loads involved in demolition of buildings made of reinforced concrete. After demolition, the remains of the concrete are fed into a crusher, and it’s vital that exceptionally hard metal, such as that used for a tooth, is not present in the mix. Otherwise that could cause damage to the crusher, something that nobody wants to witness.

A specialist demolition firm, Ottl, from Alling in Bavaria, made a specific request in the specification for this assignment: a complete reinforcement of the bucket with a 90-mm cutting edge and a new tooth system with better performance and improved durability. All of this had to be ready in record time – this Hitachi EX750 machine would have to be back in operation within ten days at the latest.

C o m b i w e a r pa rt s m a g a z i n e

The solution – ProClaws A quick solution was therefore essential. Gerhard Henle contacted Ewald Tettambel at Combi Wear Parts to ask for the best possible solution. Together, they agreed to equip the bucket with ProClaws tooth system, size W30. ProClaws is designed to withstand very high loads. Together with its low profile this system is perfect for this sort of work. They also decided to use the new mechanical locking device that

is easy to fit and which can be dismounted from the top side of the tooth. This means that tooth replacement can be performed for each individual adapter without having to dismount all teeth alongside. This gave a special advantage as this particular bucket has a very short distance between the teeth.

Fast delivery “Both the teeth and the adapters were delivered in principle overnight from Combi Wear Parts,” explains Gerhard Henle. “For this type of special assignment with extremely short leadtimes it is necessary to have a very reliable partner. When you have this type of good partner you can meet your customer’s requirement,” concludes Gerhard Henle.

Satisfied demolition expert The truck that was to fetch the bucket stood waiting with the engine running, and as soon as the reinforced bucket was loaded aboard the truck drove to the demolition site in Munich. Waiting

Returning later to the site we exchanged a few words with Franz Schweiger, who said: “This system has great wear properties and a strong wear profile. Even in the most extreme conditions, such as the breaking up of the old concrete foundations, there was nothing to complain about. This new solution from Henle has definitely convinced us.”

Valuable asteroids Asteroids contain enormous amounts of valuable metals. There are asteroids throughout space but they are especially numerous between Mars and Jupiter and around Pluto’s orbit. The cost of mining these metals would be astronomical (!) of course, but it might still be worth it.

The biggest barrier would be transport costs. To solve this problem one idea is to involve private financing models in order to exploit the profit motive.

But while we wait for these solutions to become reality we can today book a ticket aboard Virgin Galactic and take a trip through space.

Mines in space?

It sounds like fantasy, but several space agencies have already started discussing mining on the moon.

China and Canada are both seriously interested in finding out what resources the moon holds. A special moon truck is being developed that can drill on the moon and it will take its first test assignment here on Earth soon.

NASA is also producing a drilling vehicle that can drill for water on the moon. The idea is that this would establish a water supply for any future residents. But the moon isn’t the only unusual place where mining has been considered.

Water problem When the city of Athens was at its high point of development around 400 BC the silver mines in Lavrio flourished. The mines were owned by the state and slaves were used to mine the silver. The Romans then developed mining operations, but flooding caused serious problems for them. They tried to solve this by using various wheels with buckets attached to lift the water to a higher level. The steam engine invented by 14

Thomas Newcomen at the start of the 18th century was specifically designed to pump the water out of mines in southern England.

A constant flow fluctuations. This requires an attitude where optimisation is a guiding principle when taking production and stocks into consideration.

To help us we have efficient, process-driven and flexible production facilities as well as a well-established and customised planning system. As with all production facilities, the lead time varies depending on demand and that will of course not affect our customers.

We are against extensive stocks in the distribution chain, as these make the demand more irregular and difficult. This also ties up capital in idle products.

It is a matter of course for Combi Wear Parts to strive continuously to find the best possible solutions for customer needs when, for example, taking availability and logistic solutions into consideration.

Anticipating customer needs and staying updated when it comes to market demands is a big challenge for Emma Johansson, MRP (Material

Requirement Planning) and Procurement Manager at Combi Wear Parts.

The products should be manufactured as rationally as possible and they should be available when the customers need them. For that, production facilities that are both flexible and efficient are required, as well as stock management that supports the market’s short-term

Customers who choose Combi Wear Parts products and understand this interaction feel secure in their choice and we promise that we will always be able to deliver on time.

“Our goal is to achieve a constant flow, from the melting process to the end-customer, there shouldn’t be a need for any stops along the way,” says Emma Johansson.

New website Combi Wear Parts is launching a new website with a new look. It’s built in WordPress, which will help us keep up-to-date with the

latest product news and what is going on throughout our company.

We hope visitors will find it easier to use too.

Midsummer

Helan går Sjung hopp faderallan lallan lej Helan går Sjung hopp faderallan lej Och den som inte helan tar Han heller inte halvan får Helan gåååååår Sjung hopp faderallan lej

The end of June, when the summer solstice occurs, is time for one of the most popular holidays in Sweden – Midsummer. This is when the sun reaches its highest position in the sky and in Sweden it can stay light all night.

In Sweden we celebrate some old traditions with dances, games and songs. This can involve holding hands and dancing around the midsummer pole. This is mostly done for the sake of the children.

Teenagers often try to avoid this bit and just wait for night time. A midsummer pole should be covered with beech leaves and decorated with flowers and often has garlands hanging from a cross beam.

One of the more spectacular song and dance games is called “Little frogs”. The idea is to jump round the pole imitating a frog while singing. This is a great spectacle.

The chorus is exquisitely designed to mimic the sound of a frog and goes like this (please note this is a Swedish frog): Kou ack ack ack, kou ack ack ack, kou ack ack ack ack kaa. Kou ack ack ack, kou ack ack ack, kou ack ack ack ack kaa It is believed that the idea for the midsummer pole came to Sweden from Germany in the 16th century.

Midsummer food At Midsummer we Swedes eat lighter food dishes to mark the arrival of summer. This usually includes various flavours of pickled herring with new potatoes boiled in dill and served with sour cream and chives. People drink beer and maybe oa shoot of vodka flavoured with either anise, lemon, dill, elder, fennel, St. John’s wort, coriander, cumin, wormwood, bitter and sweet gale. For dessert we expect fresh strawberries with vanilla ice cream or cream.

And of course, while we eat our midsummer food we sing drinking songs. Here is the text to one of our most popular drinking songs, Helan går. You can see how to sing the song in Swedish using English words. What do the words mean?

Well, in simple terms “Drink up” or just SKÅL!

Midsummer dance After the games and food most people fancy a dance. The ideal scenario is dancing outdoors while the sky remains bright on a dancefloor covered with beech branches and flowers. Preferably this dancefloor would be beside the lake or sea so you can see the mist creep out over the water. When the dance is over and everyone goes home, girls who believe in magic might pick seven types of flower to lie underneath their pillow. This will help them to dream about the man they will marry. It’s all very romantic.

Moon minerals on Earth Three types of moon mineral have been discovered on Earth: tranquillityite, pyroxferroite and armalcolite. These minerals were among the 20 kg of moon rocks brought back to Earth

by Apollo in 1969.

And recently a third mineral, tranquillityite, was also discovered here on our planet. This find is reckoned to be about one billion years old. Scientists hope that these finds will help to explain the Earth and the moon’s history and geology.

Initially, researchers thought that these minerals only existed on the moon, but then two of them, pyroxferroite and armalcolite, were also discovered on Earth.

World’s largest pool

Unfortunately, Combi Wear Parts cannot brag that it helped to build the world’s largest swimming pool, but we cannot fail to be impressed by this amazing construction.

It is of course an outdoor pool and it can be found at the San Alfonso del Mar in Algarrobo holiday resort located near the capital of Chile, Santiago de Chile.

18

The pool is over one km long and covers an area of around 80,000 square metres and contains more than 250 million litres of salt water.

The maximum depth is 35 metres

and it’s no less than six times larger than the world’s second largest pool.

You can take more than bath duck with you when you go there. You could take a yacht if you wanted to.
