Hitachi unveils EH1100-5 rigid dump truck
Hitachi Construction Machinery has unveiled its EH1100-5 rigid dump truck, the latest version of the EH1100 RDT, at Conexpo 2014.
The EH1100-5 has many successful legacy features, such as the long-life and highly compressible NeoconE/Helium suspension strut fluid, the robotically welded fully fabricated box section frame, the highly stable trailing arm front suspension, and the reliable body floating hinge pin design.
Available for sale from April 2014, the EH1100-5 is said to include improvements to the operator environment, increased machine serviceability, increased payload, and more remote monitoring capability.
Similar to the large Hitachi mining trucks and shovels, the EH1100-5 is equipped with a 25cm LCD display to provide the operator with information regarding hauling performance and systems condition.
Many steering and brake system valves and test ports on the new RDT have been relocated from the mid-frame of the truck to the service deck of the truck for easier service and troubleshooting access. The steering filter is now located outside of the frame allowing service personnel the same ground level service access as is offered with the hoist filter.
For the market outside of North America, EH1100-5-customers can choose between an MTU Series 2000 engine and a Cummins QSK23 engine. Within North America, choice is limited to the Cummins QSK23 engine.
The EH1100-5 rear wet disc brake assemblies now include an integral wet disc parking brake. While redesigning the rear wet brakes, Hitachi added brake surface area to increase service braking and retarder horsepower.
The new Hitachi RDT model also has technology and software improvements. The company’s active traction control system has been refined to better control wheel spin in wet and muddy conditions, resulting in improved haul cycle times and increased production. Furthermore, a transmission Optimum Shift Range has been developed to automatically alter the transmission range according to payload results provided by an onboard payload weighing system.
Hitachi offers a speed limit feature on the RH1100-5 that automatically restricts the truck’s top speed to a customer determined limit.
