When i was at my first job in a factory as a trainee, they decided to remodel a manufacturing line and had to move some 40t hydraulic presses. They hired a crane, and the crane guy did the proper mounting of the presses. A 20cm steel beam through the mounting holes of the press, attached to the hook of the crane with these nylon carrying ropes. All fine.
As he lift the press through a hole in the roof, the steel beam just fucking breaks into two pieces. The whole 40t press falls to the ground from a height of 3 meters, leaving a crater of 50cm in depth in the concrete. The broken off piece of the steel beam slams into the driver cabin of the crane, which luckily was reinforced with a steel cage behind the window. This cage saved the crane operator’s life.
We were on a smoke break and watched everything. Fucking crazy.
Never step under heavy load hanging from a crane. Never ever.
