Venting the friction clutch

NOTICE

Interventions in the friction clutch will lead to a loss of guarantee!

Interventions in the friction clutch change the slip torque. Therefore the machine may be damaged considerably.

„ Never intervene in the overload protection.

„ Only use KRONE original spare parts.

Overloading and brief torque peaks limit the torque and transfer it evenly during slipping.

To guarantee the function, friction clutches must be bled before the initial start-up and after a prolonged standstill. To do this, the friction linings must be relieved and the clutch manually rotated.

The friction clutch is designed with a permanently adjusted turning torque M

R

. The torque is applied to the housing of the friction clutch (2).
