The issuing of this alert was prompted by an incident where a service technician received serious injuries when he fell 6 metres from a scissor hoist that he was working in.
He had elevated himself in the scissor hoist to repair an overhead crane that had been stopped. However the crane that he was repairing overturned the scissor hoist after a second crane that was operating on the same runway hit it.
- Repair work was being conducted on a runway with two cranes
- There were no actions undertaken to ensure that the second crane did not come into contact with the crane that was being repaired
- The actual handrail of the scissor hoist had been elevated to a point that was above the structure of the crane
- Risk assessments need to be conducted before work starts on a multiple crane runway
- Safe work procedures need to be implemented prior to the commencement of work
- Anti-collision measures need to be fitted to the cranes to ensure a collision doesn’t take place
