Komatsu 931

Strong and smart

Komatsu 931

The new Komatsu 931 is built for truly demanding logging. In severeal decisive areas it provides the benchmark for future needs of maximum production capacity, eco-friendliness and operator comfort – the most important of which are presented here.

Revolutionary 3-pump hydraulics

The 931's immense work capacity is much due to the brand new 3-pump hydraulics, split into dual circuits with separate pressure levels. The system is power-regulated against the diesel engine and offers a class-leading hydraulic capacity of 584 l/min. Unique pressure and flow optimisation enables you to work considerably faster without losing hydraulic power. You can operate several crane and head functions simultaneously with maximum hydraulic power, such as slewing the crane, feeding a log and manoeuvring the machine with optimally low fuel consumption.

Parallel crane

Fast and powerful parallel crane, easy to operate. Mechanical crane tip control. Rapid out, powerful in. Parallel curve. Agile in thinning. Contributes to lower fuel consumption.

Levelling function

The cab levelling function means that you are always seated levelly and don't need to stretch and strain to maintain good posture.
