Another sittuation of crane not enough capacity

Any accident foreseen in this frame?

A hydraulic excavator was employed in an underground construction work. Workers are trying to pull it up with another hydraulic excavator. The former weighs 2.7 tons and the latter 11.5 tons.

Now what accident do you anticipate from this picture?

This is the accident resulted!

The larger hydraulic excavator lifted up the small one and tried to swing, when the former lost balance all of sudden and fell off the ground. The lifting operator jumped out of the machine to escape the danger in vain. He was killed, sandwiched between the fallen machine and the wall.

Tips for forestalling similar accidents

1. If an object weighing over 1 ton is to be lifted up, be sure to use a crane, not a hydraulic excavator.
2. When lifting up an object under 1 ton using a hydraulic excavator, observe the instructions set forth in the Article 164 of Ordinance on Industrial Safety and Health Law.
