Hydraulic system - 6000

11.3 Description

Lift

The lifting motion occurs when the pump motor (M3) is run. Lift speed depends on load weight.

The non-return valve prevents leakage through the pump. When the load is in the lifted position, it is held in place by the non-return valve and the closed electric lowering valve (Y41).

Lower

By opening the electric lowering valve (Y41), the load is lowered and the maximum lowering speed of the forks is regulated by the flow control valve.

A pressure limit valve (overflow valve) prevents overload and protects the pump motor from overpressure. A hose rupture valve is located at the cylinder to prevent the load from falling uncontrollably in the event of a hose rupturing.

Operating pressure

Operating pressure at rated load is 190 bar.

Pressure limit valve

The pressure limit valve opens at 210 bar.
