Komatsu 855

Powerful yet compact

Komatsu 855

The Komatsu 855 makes it easy to deliver. With its power, nimbleness and smart solutions, the Komatsu 855 is a forwarder that offers you long-term productivity in all situations.


Smoother and faster transport

Komatsu Mini Steering Wheel means more space in the cab and a more comfortable driving experience. SpeedShift (Option) enables you to drive the machine at any speed between 0 and about 23 km/h without stopping to change gears – increasing productivity and saving fuel.

Efficient loading

The crane has a long reach and a high net lifting force, a reliable pillar and hose routing solution and a Combi outer boom. Tiltable crane pillar (option) for efficient loading in steep terrain.

Flexible bunk with high load capacity

The Komatsu 855 has a large bunk characterised by its flexibility and many options. One is FlexGate, the gate that improves visibility and flexes out of the way if struck by the crane. This simplifies loading and minimises the risk of machine damage. Another is FlexBunk, which with its hydraulic height-adjustable stakes and option to widen the bunk provides a high load capacity.

Easy to maintain

Service and maintenance are quickly and easily conducted. All daily service can be performed from ground level via easily accessible service hatches and the dipsticks are quickly and easily checked. The engine hood is electrically powered and the filters are strategically located together for easy access under the hood. The forwarder has many conveniently located service hatches.
