Bridge crane collapse (14 March 2024)

A 10-tonne bridge crane collapsed at a workshop while being operated by two workers. The crane was being used to conduct bucket flips in a manufacturing process for front end loader buckets. The process involved rotating the buckets to complete work on the underside. A bucket weighing approximately 7-tonne was being flipped using the crane when the crane and attached bucket collapsed to the floor. No one was injured in the incident.

Safety information

Consider ‘reasonably practicable’ control measures to manage the risks associated with operating bridge cranes.

Ensure:

  • the rated capacity of the crane is not exceeded, refer to the operator’s manual or crane specifications
  • the weight of the load is calculated prior to being hoisted
  • a test lift is conducted to ensure load security and stability
  • when slinging loads, consideration must be given to:
    • the weight of the load
    • reeve and angle factors
    • size of the load
    • slinging technique
    • hoisting clearances
  • the crane hook is positioned over the load’s centre of gravity to avoid dragging or snigging the load
  • lateral tolerances or side loading of the crane are not exceeded
  • an exclusion zone is set up around the plant and any loads
  • workers do not perform work on a suspended load
  • the workpiece (load) is placed on appropriate supports and remains detached from the crane while undertaking work
  • crane attachments are securely attached and used to perform the tasks in the manner they were designed for by the original manufacturer
  • the path of travel is clear from obstructions when a load is hoisted by a crane, and the load remains under control
  • workers receive adequate training and instruction
  • workers are supervised by a competent person
  • workers hold valid high risk work licences for the bridge crane if the crane is operated from a cabin or a remote if it has more than three powered operations
  • instructions and work procedures are translated for culturally and linguistically diverse (CALD) and migrant workers
  • workers complete a site induction prior to commencing work
  • a risk assessment is completed prior to commencing work
  • safe systems of work are developed and followed
  • appropriate personal protective equipment (PPE) is worn
  • lifting equipment such as slings are inspected before and after use and discarded if damaged or if wear tolerances are exceeded
  • crane pre-start and operational checks are carried out to check for defects and to ensure the crane is safe to use.
