Flexibility and strength for versatile assignments

Our all-round forwarders have a compact size that allows them to manoeuvre easily, even in tighter stands, while the strong transmission and powerful crane allow them to work with high productivity.

In other words, they are the ideal choice for those who work in both late thinning operations and lighter final felling.

Customise your load space for increased productivity

Komatsu forwarders offer flexible load areas with customisable solutions that increase your productivity. With the FlexBunk option, you can easily customise the bunks to match your specific work requirements.

If you choose the optional LoadFlex package instead, you get a flexible and efficient load space with optimised capacity. The articulated bunks are easily adjusted with the forwarder's crane, allowing you to customise the width of the load space for each individual job. What's more, the changeover is very fast, so you're ready to go from transport to production quickly.

The hydraulically height-adjustable stakes make crane operations faster and also contribute to better fuel economy.

The transmission for tough conditions

Komatsu forwarders are built for good off-road performance, but for particularly tough conditions, something extra is sometimes needed. That’s why we offer the XT transmission for some of our forwarder models.

A Komatsu 855 with the XT option is equipped with a more powerful bogie with hub reductions. The hub reductions are a great advantage when working in difficult conditions, such as steep, snowy or wet terrain, as they increase the service life of the bogie and thus the reliability of the machine.
Komatsu grapple

Handle timber like a pro

Komatsu grapples are designed to deliver high productivity in tough environments. With a large opening and good retraction properties, the grapples make it easy to gather, straighten and grip timber quickly and efficiently.

The 11 different models, including specialised variants for bioenergy and heavy-duty applications, ensure there is a grapple for every need. Their robust design and high durability make them a reliable tool, helping you to work more efficiently and profitably.

Some of our forwarder options

Komatsu 855

Flex Bunk - Complete flexibility

Flex Bunk is our flexible bunk system that can be customised to meet your specific needs. The standard version includes fixed stakes and a standard bunk width, but with several options available to allow you to easily tailor your load space.

Hydraulically adjustable stakes provide faster crane operations and improved fuel economy. Using the widening kit, the width of the load space can be easily adjusted using the crane as required*.

Komatsu 895

Load Flex - Premium load performance

The Load Flex option optimises both flexibility and load capacity. The cleverly designed bunks allow you to easily adjust the width of the load space for each job. Narrow, medium or wide - the articulated bunks are quickly adjusted using the forwarder's crane.

The wide load space provides a low centre of gravity for increased stability and smoother off-road driving. The option also includes hydraulically adjustable stakes, for more efficient crane operation and lower fuel consumption.

Comfort Ride 2021

Komatsu Comfort Ride

A forwarder operator spends many hours a day in the cab, making a pleasant and comfortable work environment extremely important. Komatsu Comfort Ride efficiently dampens jolts and vibrations, ensuring an ergonomic work environment. This in turn contributes to higher productivity and better profitability.

The new generation of Komatsu Comfort Ride comes with comfort-enhancing features like adjustable sideways firmness and automatic side levelling at standstill and at low speed. The elevated unloading mode now also works at low speed, to make it smoother to reposition the forwarder at the landing. Great news for all forwarder operators!

Komatsu Smart Crane

Smart Crane

Since such a large share of a forwarder operator's working day involves crane operation, increased efficiency offers great potential. Smart Crane provides the operator with advantages such as simpler crane operation, less physical strain and higher productivity. Advantages that benefit both profitability and the operator's wellbeing. Everything to make it as easy as possible for the operator to focus on what is truly important – moving timber to the roadside.

SpeedShift

Speed Shift

Speed Shift is a smart gearbox solution with dual hydrostatic motors, with the forwarder automatically changing up a gear as the operator increases speed. This enables the machine to accelerate continuously within the full speed range without any additional operator intervention. In this way, the engine can work at optimal engine speed most of the time, which saves fuel and provides a quiet and more comfortable work environment.

The automatic gear changes enable increased transport speed where ground conditions allow. This can include, for example, relatively flat access roads in otherwise hilly terrain that can be covered at faster speed. The longer the forwarding roads, the greater the benefit offered by Speed Shift.
