Hydraulic
Hydraulic system
A double axial displacement pump supplies the open loop hydraulic system, allowing all functions to be operated simultaneously. To minimize peak pressure, an automatic working pressure cut-off is integrated into the pump. All filters are electronically monitored. The use of synthetic environmentally friendly (biodegradable) oils is possible.
Swing
Consists of roller bearing with external teeth, swing drive with fixed axial piston hydraulic motor, spring-loaded and hydraulically released multi-disc holding brake, planetary gearbox, and pinion. Both swing modes are possible – speed control or free swing. A multi-disc holding brake acts automatically at zero swing motion, with swing speed from 0 – 3 rpm continuously variable.
