Komatsu Europe launch HD785-8 rigid dumptruck

Komatsu HD 785-8 rigid dumptruck

New 90-tonne dumptruck designed for safety, performance, operator comfort and productivity

KOMATSU Europe have launched the new HD785-8 rigid dumptruck. Based on 100 years of Komatsu experience and know-how, the truck is said to deliver the highest levels of safety, performance, operator comfort and productivity.

‘The new HD785-8 offers excellent operator comfort, great travel performance and the well-known Komatsu reliability of the previous model,’ said Juuso Ahola, product manager at Komatsu Europe.


Built for mine and quarry applications, the HD785-8 is powered by an EU Stage V Komatsu SAA12V140E-7 engine (849kW/1,140hp) and has a payload capacity of 92.2 tonnes.

The EU Stage V after-treatment solution uses dual Komatsu Diesel Particulate Filters (KDPF) whereby most regeneration is performed passively, with no action required from the operator and with no interference to machine operation. There is no Selective Catalytic Reduction (SCR), and Diesel Exhaust Fluid (DEF) or AdBlue is not required.

Key machine metrics for utilization, production and machine health can be accessed remotely via the KOMTRAX telematics system or on the machine itself through an upgraded monitor.

The HD785-8 has a seven-speed, fully automatic transmission with two selectable reverse speeds. The Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS) ensures smooth clutch engagement for a comfortable ride and reduced material spillage.

With a tight turning radius of 10.1m, the HD785-8 provides exceptional manoeuvrability when spotting for loading and positioning to dump. The Auto Idle Shutdown reduces unnecessary idle time and operating costs.

The Komatsu Traction Control System (KTCS), which is standard on the HD785-8, automatically applies pressure to independent brake assemblies for optimum traction in various ground conditions, whilst wet multiple disc brakes on all wheels provide superior downhill brake retarding performance.

Safety is Komatsu’s number one priority and to this end the HD785-8 is equipped with LED lights, ground-level battery, starter and machine lockout disconnect switches, and a newly designed stairway that provides safe access to the cabin. Moreover, Komatsu KomVision is fitted standard, creating a real-time 360-degree bird’s-eye view on the cab monitor and eliminates any blind spots on the rear and sides of the machine.

Operator comfort on the HD785-8 is catered for by a new ergonomically designed cab and a new, fully adjustable, fabric-covered air suspension seat with seat heater and ventilator as standard.

Thanks to the machine’s low-noise engine, large-capacity viscous cab mountings, hydro-pneumatic suspension and independent strut-type suspension on the front wheels, in-cab noise levels are kept at 72dBA.

Radiator cleaning has been made easy thanks to the hydraulic radiator fan with reverse mode, whilst the ground-level jump-start receptacle and service centre with Wiggins fast-fill coupler for engine, transmission, brake oil and coolant refills further facilitates easy and safe maintenance. For safety at height, technicians can attach lanyards to tie-off points positioned around the HD785-8.
