OPERATION
4.1
General
Before using the chain blocks, observe the marking and select the correct size according to the
load to be lifted.
Prior to each use, the chain blocks must be visually checked for damage or incorrect functioning.
In order to check the load brake for each new lifting operation, raise the load a little first and
stop again before lifting the load completely. In order to operate the brake mechanism, it is
necessary to apply a minimum load
. (See table for technical data)
Use chain blocks only in the temperature range from -10 °C to +50 °C.
Position the chain block between centre of gravity of the load and the suspension point.
Ensure the hooks are seated correctly and the safety latches are engaged.
Also make sure that the load chain is not twisted or has knots or damages.
4.2
Lifting the load
Pulling the hand chain in the direction of the "U" = ‚Up’.
4.3
Lowering the load
Pulling the hand chain in the direction of the „D“ = ‚Down’.
You may need a little more force to release the brake.
4.4
After use
Remove foreign objects or dirt from the load chain and the chain block. Check the load chain, hook
and safety latches to ensure that the chain block can be used again. Store chain blocks in a dry,
clean place.
4.5
Slipping clutch
The slipping clutch is set at the factory to approximately 1.6 times the working load limit and is
exclusively for overload protection of the chain block.
It may not be operationally used or actuated.
The slipping clutch must only be set by the manufacturer or authorized competent persons.
Repeated checks of the slipping clutch adjustment at short intervals (e.g. after rental) impair the
functionality and are therefore not permissible.
