Hydraulic system

Function

Starting machine travel:

If high pressure is applied to a traveling drive, the brake valve is first moved in the corre-
sponding direction and the oil moves the eccentric gear of the Gerotor in the respective
direction of rotation.

Stopping:

As soon as no more pressure is applied to the traveling drive, the integrated brake valve
returns to its initial position by spring action.
This interrupts the oil flow from the motor.
A braking effect sets in and the excavator stops.
The brake valve is dampened for smooth braking.
This also works on slopes and keeps the excavator in its position.
