3.2.5 Start and run up
The machine is started with a hydraulic system up to rated speed to avoid high start-
ing currents. During run-up, the rotor speed is continuously monitored and adjusted
to rated speed. Only after remaining steady at rated speed, the hydraulic system is
switched off, and the main motors are switched on. The overriding clutch, which con-
nects hydraulic motor and electric motor, during run-up works in lock-in operation and
with switch-off of the hydraulic system in free-wheeling operation. This clutch works
wear resisting because of the hydro-dynamic clamping piece lift-off.

Reducing the swing contact pressure
The cylinders with the knuckle eyes on the swing are connected with the ac
cumulator on the hydraulic unit and are continuously pressurized. The function
is continuously active. The initial pressure is set with a manually operated
three-way cock.
