End stop
The end stop operates the limit switch during the down movement of the chain and prevents the chain
from running out of the hoist. In the unlikely event of a failed limit switch the end stop operates as an
emergency stop and lets the clutch slide. It s not allowed to use this emergency stop permanently.
