Case 1- Mobile Crane Collapse at Worksite 17

JAN 2012

Background A 50-ton truck mounted variable boom crane toppled over during concreting operations. There were no injuries.

Occupier The Project involved the Construction of a Multi-storey Car Park within a Residential Estate

Observation & Findings

Lifting plan had no indication of the working radius and its respective SWL Electrical wire of the load sensor was damaged when the crane hit tree branches Crane Operator was aware of defective load sensor but continued lifting operation Likely that accident was due to overloading of the crane

Intervention The site was issued with SWO The Crane Operator licence was suspended with immediate effect
