New Hitachi EH1100-5 rigid dump truck

Hitachi Construction Machinery Co., Ltd. (HCM) has unveiled the new EH1100-5 rigid dump truck at the CONEXPO-CON/AGG trade show in Las Vegas (Fig.). The new truck has been designed to offer a more comfortable and safer operating environment, easier access for service and maintenance, and higher levels of productivity than previous models. It also has several advanced technology features to satisfy the requirements of its European customers.

The enhanced cab now includes a 10-inch LCD monitor – similar to the one found on large Hitachi mining trucks and excavators – to provide the driver with information on hauling performance, systems updates, and electronic maintenance and troubleshooting. A mechanically hinged rail at the front of the cab can be positioned to provide the operator with optimum haul road visibility while the truck is in operation, or positioned to provide protection from falls when the cab area is being serviced. The rear-view camera display can also be shown on the LCD monitor.

Additional safety features include the cab’s redesigned ROPS structure ­– which meets the requirements for using the EH1100-5 as a water truck – and three-point seatbelts have been built into each type of seat. The operator’s exposure to noise has been significantly reduced by the use of soundproof material in the cab and exhaust system modifications.

The new dump truck has been designed with a capacity of 41.5m3 and has a flat floor plate for greater control of the material shed while dumping. The nominal payload recommendation for the standard model is 63.5 tonnes. To enhance the overall performance and safety of the EH1100-5, Hitachi redesigned the rear wet brakes to include an integral wet disc parking brake. During the redesign, Hitachi also added brake surface area to increase service braking and retarder horsepower. A refined active traction control system ensures greater control of wheel spin in wet and muddy conditions. The EH1100-5 is equipped with a DLU (data logging unit) to allow remote monitoring of the truck via satellite, Wi-Fi and Wenco. Hitachi also offers a speed limit feature that automatically restricts the truck’s top speed to a limit set by the customer.
