Back 22

Location of examination

Crane model and type

Details of who carried out the inspection

SWL

Front 23

To whom should the appointed person give all details involving the lifting operation?

Back 23

The crane Supervisor and all parties involved in the lifting operations

Front 24

What advantage is there in increasing the number of falls on a hook block?

Back 24

It can allow heavier loads to be lifted within the confines of the Crane duties chart, so higher lifting capacity.
