PADDING BUCKET EXCAVATOR

MB Crusher

Padding bucket

MB Crusher’s MB-HDS220 padding bucket has a 1-tonne weight, 0.6-cubic-metre capacity. The bucket is designed for skid-steer and compact loaders ranging from 4.5 to 11 tons. Suited for gardening, landscaping, and urban construction sites, the padding bucket aerates packed topsoil for landscaping and can also be used to reclaim clean soil from demolition debris, stones, or roots. A 2.20-metre inlet mouth opening aids loading by ensuring that the carrier machine’s tracks or wheels remain clean. Greasing is centralized and done on-site. The coupling system is designed to aid maneuverability by increasing visibility of the material. The MB-HDS220’s rotors can be changed on-site by the operator. John Deere Construction & Forestry

Large excavators

John Deere has added three new P-tier excavator models to its large excavator lineup. The 470 P-tier, 670 P-tier, and 870 P-tier models deliver improved visibility features including right, rear, and left cameras with LED surround lighting. The lighting and cameras provide the operator with a 270-degree view of the area around the machine. All three excavators feature auto-idle technology which reduces engine speed when hydraulics are not in operation. The excavators use an auto-shutdown feature to preserve fuel, and a hydraulic reversing fan keeps the coolers clean in high debris environments. The 470 P-tier is available with optional grade management solutions, and may also be ordered with a hydraulic coupler-ready option.

WHEEL LOADERS TILTROTATOR

GENERATOR

Doosan Portable Power

Generators

The power needed to start motors usually dictates the size of the chosen generator. After the motor is started, the load on the machine drops. But running a generator at a low load is not recommended for Tier 4 Final engines and can lead to engine wet stacking. Doosan Portable Power’s 20kVA to 50kVA generators use upsized alternators to solve this issue. Large alternators give smaller generators more motor-starting capability. Operators can get the initial energy needed to start the motor and then continue to work with an ideal load. The 20kVA to 50kVA generators have a digital control panel that displays the tachometer, oil pressure, coolant temperature, and fuel level. A digital meter shows AC output, generator voltage, and current.

Caterpillar

Tiltrotators

Caterpillar’s new Tilt Rotate System (TRS) models fit Cat mini excavators. The new TRS4 and TRS8 S45 plus updated TRS6 models enable work tools to rotate 360 degrees and tilt 40 degrees side-to-side. Interface connections for the TRS4, TRS6, and TRS8 include a choice between an S Type hydraulic coupler or pin-on, while bottom interface options include a pin grabber or an S Type coupler. The compact design of the tilt rotate systems allow the mini excavator to maintain ideal digging force. A TRS gearbox with a specially designed bearing ring distributes working forces to reduce stress on the TRS and the host machine, and a no-maintenance lubrication system for the rotation system effectively distributes heat.

Volvo Construction Equipment Electric wheel loaders

Volvo has updated its first two electric compact wheel loaders with additional features including higher speeds and linkage options, as well as optimized charging. The L20 and L25 compact wheel loaders have a maximum speed increased to 12.4 mph (20 km/h), along with an option to add a parallel linkage, which offers high breakout torque in a number of applications. A new hydraulic pump and repositioning of the main control valve from the cab to the front frame reduces noise even further. Volvo has added a programmable cab heater option for programming which days to pre-warm the cab. Hill-hold functionality has been added thanks to a new electric parking brake, and the disc brake has been removed in favour of a spring-applied and hydraulic-released wet-disc brake, which reduces maintenance.

Volvo’s Electric Machine Management Application (EMMA), provides users with insights and information on one machine or several, ranging from charge status to location.
