Crane Load Falls (KV107)


What Happened?

At 9:45 a.m. on May 16, 2017, Employee #1 and Coworker #1, employed by a construction erection company, were working at a multiemployer job site. Employee #1 was assigned to install precast concrete docks plank and was waiting for the load to arrive for installation. Coworker #1 was operating a lattice boom crawler crane and delivering a concrete plank measuring 30 feet long. The crane stalled. When Coworker #1 restarted the crane, the boom descended rapidly, and the load landed on Employee #1. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for a fractured ankle.

Contributing Factors

Improper body positioning. At no point should anyone ever be under a suspended load.  

What Can We Learn?


Using the Self Check tool would have helped the employee identify his tasks step by step and safe body positioning away from a suspended load.

Questioning Attitude would have also made the employee think about what the worse outcome could be by placing himself under a load.


The employee was caught in the trap of Overconfidence. Employee #1 should have never been under a suspended load.
