Checking the requirements

 

The following requirements must be met in order for the chain hoist to be mounted.

 

Checking the load capacity

─     The supporting structure (steelwork, building, crane installation) from which the chain hoist is to be suspended must have a sufficient load capacity.

 

The load capacity of the supporting structure is derived from the weight of the chain hoist, the maximum load capacity of the chain hoist, the weight of the trolley (if applicable) and possibly the additional weight of the chain as well.

 

*   For the weight of the chain hoist, refer to the table.

*   If the hook path of the chain hoist is longer than 3 metres: Add the additional weight of the chain.

*   Check the entire supporting structure as to whether it will support the expected load.
