Operation
7.3

Brake and pawl

The brake remains closed (stuck) if:
The ratchet lever hoist is uncharged without lowering the load, i.e. in case of vertical lifting/lowering when
a load is "transmitted" to another hoist or in case of horizontal pulling/tensioning.
The load hook is pulled against the housing and got stuck there
The chain does not move, the load cannot be lowered.
Remedy:
Charge the ratchet lever hoist again
Release the brake by setting down the load
OR: Turn the switching pin to position "Lowering" and release the hand lever with a strong jerk in direction
"▼".

Transmission of loads

When loads are transmitted from one hoist to another, the hoist that gets the load is not possible to lift or
lower as the brake is closed at the time of transmission.
Proceed as follows in such cases:
Lift the load with the hoist (A).
Suspend the load from the hook of hoist (B)
and lift it unil the load hangs securely in the
hook, but do not uncharge the hoist (A).
Effect movement lowering with hoist (A) until
hoist (B) takes over the complete charge/load.
Now hoist (A) is uncharged and the brake is
open again.
