Moving parts with a crane
Taking down from a construction machine, a worker is now putting a control valve on a working bench with a crane.



Various Points of Hazard
1. Unless the worker brings the working bench direct under the hoist, the bench may be pulled down toward the worker due to the weight of the control valve.
2. The worker's left hand may likely be crushed under the descending control valve.
