New hydraulic system increases productivity and reduces fuel consumption

Komatsu Forest have launched a new, unique hydraulic pump system – 3PS – that effectively helps increase productivity and improve fuel economy. The new triple pump system is the first hydraulic system that enables forest machine operators to perform several tasks at the same time, thereby increasing production. Operators can quite simply harvest more in less time.

Since the new hydraulic system has three hydraulic pumps split into several hydraulic circuits, high hydraulic power availability is always guaranteed. This enables the operator to use several hydraulic functions at the same time without the machine being limited by the availability of hydraulic power and hydraulic flow.

Parallel to this, the energy efficiency of the new triple pump system results in fuel savings for the machine owner as fuel consumption per processed cubic foot is considerably lower compared to a harvester without a triple pump system.

The new 3PS hydraulic pump system is based on three hydraulic pumps wherein the transmission pump is separate from the other two pumps, which are only used for the machine's working hydraulics. The working hydraulics are split into two circuits, a high-pressure circuit and a low-pressure circuit. For processing tasks that require a great deal of oil – or hydraulic power – the two circuits are combined for maximum power and performance. The low-pressure circuit is otherwise used for hydraulic functions with lesser needs, so that the 3PS system does not produce unnecessary hydraulic power. Hydraulic power demands are also coordinated with the diesel engine's power output and system power is regulated by the MaxiXplorer control system.
3PS is featured as standard on the new Komatsu 901, Komatsu 911, Komatsu 931, and Komatsu 951 harvesters.
