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.


More power for sustainable productivity

We have a brand new engine installation conforming to the latest emission legislation (Stage V). It also offers you many other advantages, such as an all new AdBlue system, a new exhaust system and hydraulic tappets. Despite the new larger engine installation we’ve managed to keep the same slim design with good all round visibility and views of the machine – right down to the wheels.

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 24 km/h without stopping to change gears – increasing productivity and saving fuel.

Excellent operator environment

The cab is spacious with plenty of legroom and numerous storage solutions. The large windows offer fantastic visibility upwards, downwards and to the sides and make crane operation easier and more relaxed. The cab has a low noise level and a driver’s seat that offers superb comfort and a large working range. Naturally, Comfort Ride cab suspension is available as an option.

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.


The machine is ready for installation of MaxiFleet, the world's first fleet management system for forestry machines. A unique tool that enables searches, compilations and presentations for all the machine and production data that your machine generate, with the powerful MaxiXT as the informations source.
