Dangerous sittuation on the slope of mountain

Any accident foreseen in this frame?

This is a worksite for building a construction road. A hydraulic excavator is pulling hewn logs with a chain to remove them from the site.

Now what accident do you anticipate from this picture? 

This is the accident resulted!

The tugged logs were sent leaping and went down the slope on the valley side. Linked with a chain, the upper structure of the machine was then widely swung, then lost balance and rolled over. The operator was crushed under the fallen machine.

Tips for forestalling similar accidents

1. Use a special purpose machine for transport of logs such as skid loaders.
2. Operate a construction machine within its maximum capacity.
3. Fasten a wire rope securely to the logs.
