Komatsu HD785 Maintenance Manual PDF
The Komatsu HD785 is a massive haul truck built for moving large quantities of rock and other bulk materials for building and infrastructure projects. Even in the worst of weather and road conditions. You may load up to 91 tons onto this machine.
The dump truck can travel up to 65 kilometers per hour thanks to its high-powered Komatsu SAA12V140E-3 engine, which generates a net of 879 kW (1196 hp). With its large frame (heaped capacity of 60 cubic meters), enhanced performance, and high production levels, all at comparatively cheap running costs, this vehicle is a steal. In addition, this dump truck has enhanced energy economy and uses reasonable amounts of diesel fuel compared to other vehicles in its class.
The VHPC system allows for the administration of the vehicle’s operating modes; the vehicle’s interior boasts greater comfort; there are two reverse gears; the body is spacious; the vehicle has a fairly short turning radius.
All of the Komatsu HD785’s components are mounted on a box-section chassis with an integrated front bumper fabricated from specialized high-strength steel grades.
The truck’s independent suspension, which uses pneumohydraulic cylinders and has fixed throttles, dampens noise and vibrations. The dump truck’s Komatsu HD785 model has a 1308-liter fuel tank, completely hydraulic steering with double-acting cylinders, and multi-disc devices on all wheels (“in a circle” – oil cooled and hydraulic drive).
To further lessen the machine’s ecological footprint, the Komatsu HD785-7 has a lead-free radiator and an EPA-approved Tier 2 Komatsu SAA12V140E-3 engine. A further benefit is that there is less noise both within and outside the cab.
The maximum torque for these trucks is 5080 Nm at 1300 rpm, and their net power is 879 kW / 1196 hp at 1900 rpm (ISO 9249 / SAE J1349).
Water-cooled, turbocharged, intercooler, electronically controlled direct injection, and a gear pump-driven positive lubrication system are just some of the features of this 12-cylinder V-shaped diesel engine’s 30.48-liter capacity. It has a 140 mm bore and a 165 mm stroke.
These engines’ fuel injection and regulator systems are state-of-the-art and electronically regulated for maximum efficiency.
