LLCR – Toppling of Stacked Boom Section in a Crane Maintenance
Workshop
Incident
On the incident date in June 2007, a group of workers were
dismantling a telescopic boom into its individual sections using
an overhead travelling crane. After stacking a dismantled boom
on top of another boom section, the Crane Operator began to
hoist the chain slings away. As the slings were being hoisted
away, the stacked boom toppled onto a nearby worker. He
succumbed to his injuries.
Summary of Findings
Investigation revealed that the incident occurred primarily
due to the negligence of Man (Crane Operator
and Worker). The Crane Operator did not do his due diligence
to ensure that the chain slings were free from entanglement
before hoisting away. The worker should have positioned
himself in a safe location, away from the lifting zone.
Management
also did not establish the necessary safe work procedure for
the stacking of boom sections. All these led to the occurrence
of this fatal incident.
