The crawler crane utilises the full benefits of LSC technology: the combined movement of individual functions without mutual interactions or influences in all load situations ensures perfect positioning. Furthermore, the crane also benefits from jolt-free lifting and no lowering of loads at the start of the movement. The crane's design as a two-circuit system with two high-pressure self-regulating pumps for different pressure levels increases the demand-specific supply to the actuators, which makes the machine even more efficient. This ensures excellent load capacity in all working conditions. The superb low speed behaviour and the smooth, even running characteristic of the Linde motors is particularly noticeable when it comes to lifting and lowering the hook.
The individual valve sections in the control plates of the VT modular family can be actuated fully hydraulically or electro-hydraulically. The two types of control can also be combined in one control plate.
Thanks to the electronic controller, selected functions can also be operated by remote control or partially automated. Sophisticated safety systems are also possible, which can be implemented via locking mechanisms or through proportionally slower reactions from individual actuators in given situations.
Even without the use of position sensors, the machine can be equipped with the functions of the LSC+ system. In particular, this includes switching between rough control or fine control, or overriding the LS signal if load-dependent machine reactions are required. The maximum efficiency of single actuators is achieved, when they are controlled purely via the pump with fully open directional control valve pistons.
