| While extracting steel sheet piles, a worker connects the
chuck portion of the Vibrohammer to the steel pile, and starts the machine. |
|
Because the worker turned on the Vibrohammer without securing the hydraulic chuck, the Vibrohammer started shuddering, came off its hook, and fell onto the worker.
|
| Tips for preventing similar accidents
|
| 1. |
Only start a Vibrohammer after securing the chuck and ensuring that it is being firmly pinched. |
| 2. |
Be sure to inspect the safety catch for the hook before starting work. |
| 3. |
Only allow personnel certified to operate a vehicle-type construction machine for foundation work to perform pile extraction work. |
| 4. |
Undergo preliminary training on the proper methods for operating machinery, such as methods of starting up a Vibrohammer from a remote location. |
