MARUBENI-Komatsu has introduced the new HD785-8 rigid dump truck, which has been built for quarry and mining applications.
The model is powered by an EU Stage V Komatsu SAA12V140E-7 engine and boasts a payload capacity of 92.2 tonnes.
After treatment solutions use dual Komatsu Diesel Particulate Filters (KDPF). Most regeneration is described as being performed ‘passively’, with no action required from the operator and with no interference to machine operation. There is no Selective Catalytic Reduction (SCR), while neither Diesel Exhaust Fluid (DEF) or AdBlue are required.
The HD785-8 has a 7-speed, fully automatic transmission with two selectable reverse speeds.
Juuso Ahola, product manager at Komatsu Europe said, “The new HD785-8 proposes excellent operator comfort, great travel performance and the well known Komatsu reliability of the previous model.
“This new machine is such a pleasure to operate that you just might want to keep the keys at the end of your shift rather than hand them over to the next operator.”
With a turning radius of 10.1m, the machine is said to provide ‘exceptional’ manoeuvrability when spotting to be loaded and positioning to dump.
The Komatsu Traction Control System (KTCS) is fitted as standard. This automatically applies pressure to independent brake assemblies for optimum traction in various ground conditions.
Safety features include LED lights, ground level battery, and starter and machine lockout disconnect switches. A newly designed stairway provides safe access to the cabin.
Komatsu KomVision is also a standard feature, creating a real-time 360-degree bird’s eye view on the cab monitor and eliminating blind spots on the rear and sides of the machine.
The HD785-8 has a new ergonomically-designed cab with a fabric-covered, air suspension seat, which is adjustable to the operator’s weight and height. Also included is a seat heater and ventilator.
Radiator cleaning is boosted by a hydraulic radiator fan with reverse mode. For safety at height, technicians can attach lanyards to tie-off points placed around the machine.
