The new HM400-3 from Komatsu caries a full 40tonnes
The new HM400-3 articulated dump truck (ADT) from 2300 Komatsu can carry a full 40 tonnes and features a host of new technology in the drivetrain and in the cab.

Its 353kW engine is fitted with a diesel particulate filter with computer-controlled regeneration so that no operator input is required.

A computerised Transmission Control System replaces the need for limited slip differentials in the transmission as it activates the multi wet disc foundation brakes in any wheel that starts to spin. Furthermore, the system is also used as a retarder and reduces the weight of the transmission.

An A frame design carries the front wheel and does away with the need for a solid front axle and improves the ride quality. Inside the cab are separate monitors for the machine control and rear view camera, while the tip control is now also fully electronic.

A redesigned 24m 3 body has thicker steel than its predecessor and is elevated by new single-stage rams, which cut the laden tipping time to 9seconds. When reverse is selected the angled rear view camera and lights are activated to provide a view from one tyre to the other and complement the large mirrors mounted by the cab.

  • C-series CX470 excavator takes centre stage on Case’s INTERMAT stand
    January 6, 2017
    A 6% increase in lift capacity, greater digging efficiency, reduced emissions and up to 5% lower fuel consumption are the benefits of Case’s new CX470C excavator. The 47 to 50tonne machine has a 9.8litre Stage IIIB engine delivering 270kW at 2,000rpm which contributes to a 5% increase in fuel efficiency and 5% faster cycle times. Some of the savings come from a Boom Economy Control, which automatically reduces engine revs and hydraulic power to the boom when speed and power are not a priority.
