Linde components are robust, field-tested and designed for a long service life even in heavy duty applications. The example design depicts the propel drive system in a closed circuit, which provides precise, controlled directional stability and wear-free steering, especially with regard to soil protection. The saw is driven by a separate drive in an open circuit. The other machine functions are realized using a LSC valve block which distributes exactly the demanded flows.

Thanks to the parallel architecture of the LSC System and the block's modular design, based upon infrastructure modules and sub plate-mounted valves, one MCV provides a common basis for differently equipped machines. In a machine with an open circuit drive system design the other components do not change greatly: The MCV block can simply be extended with the required valve sections and pump fittings if necessary. The rest of the components remain the same, which simplifies storage and reduces the training requirements of service personnel.

Beyond that, the modular design offers the ability to customise machines even in the field.

Thanks to the LSC system, no actuator stops unexpectedly or reacts unpredictably when the system's demand exceeds the diesel motor power. Keeping the actuator responses proportionally identical makes the machine safe to control in any situation. LSC also prevents open circuit propel drive systems from unforeseen turning due to obstacles such as tree stumps. If an obstacle causes the system pressure on the drive side to increase, the oil does not flow to the other side - both drivetrains continue running at the same speed.

A layer-brazed valve block distributes the volume flows in the processing head. It is characterised by an extremely compact design and excellent electro-hydraulic actuation behaviour. Linde is also the perfect partner for other forestry machines, as well as wood processing and handling machines.
