Unloading of boom cylinder
Two mechanics are unloading a boom cylinder weighing 73 kg from a service truck together. One is handing it over, standing on the truck body, while the other is receiving it on the ground.



Various Points of Hazard
1. The two workers stand on places of different height. The fact means the center of gravity of the boom cylinder shifts forward. For this reason, they may let if fall on the ground by mistake.
2. The weight may overpower the two workers, who may let it fall on the ground, unable to hold it any longer.
