Overhead Crane Controls:
20 Ton Bridge Crane unexpectedly moved and seriously injured workman, Napa, CA,
- Pipe fabricator (PF) seriously injured by 20 ton crane hook and pulley when crane moved without command.
- Manufacturer stated in their operation manual for the wireless remote controls that stray signals could cause a crane to move unexpectedly and that all installations should be tested for stray signals.
- I discovered that the FOUR cranes in the building had the same brand and model of wireless remote controls.
- PF clearly did not command the crane movement, evidence was found that other cranes in the plant had reported rouge movements.
- The owner had a Crane Mechanic try to fix the problem on multiple occasions, which reoccurred again after several months.
- My investigation found that the default settings of the remote control came from the factory with the automatic scan feature enabled so that when an operator performed a specific unusual task the automatic scan function would scan and lock on to another crane control IF it was transmitting. This was the cause of the apparent rouge (stray ) signals
