Checking function of slipping clutch without load
1.
Without load, run bottom hook block to top or bottom hook position.
2.
Allow clutch to slip in top or bottom hook position for a maximum of 3 sec. The chain
must not move, the motor must rotate.
WARNING
Danger of bodily injury and material damage
Slipping clutches and brakes may only be adjusted by a qualified person.
➢
The motor must be at a standstill during all work on the slipping clutch.
When starting to adjust the slipping clutch, the chain drive must be off-loaded! We
recommend consulting our after-sales service. Before being adjusted, the function of the
slipping clutch must be checked.
7.3
Adjusting slipping clutch - without load
The slipping clutch can be tested easily with the FMD1 slipping clutch testing device, and
adjusted if required without any danger to the structural steelwork.
125%+15% of maximum working load is the specified value for the slipping clutch.
The function of the chain hoist must be tested with maximum working load at least once a
year. Adjusting the slipping clutch with this testing device does not replace this test!
