Worker dies in vehicle hoist collapse

February 11, 2020 Mining Editor

The death of a 66 worker in a vehicle hoist collapse in the Northern Territory has triggered a range of safety alerts across vehicle maintainers and vehicle hoist manufacturers and certifiers. The fatality appears to have resulted from the removal of a range of safety components from vehicle hoists.

The Northern Territory regulator confirmed that in October 2019 a workplace fatality occurred, involving a modified vehicle hoist.

According to information available, “a  4 post vehicle hoist was in an elevated position with a vehicle positioned on top of the wheel platforms. The worker was standing under the hoist conducting mechanical repairs. His upper body was between the under carriage of the vehicle and the front section of the hoist when the vehicle unexpectedly rolled forward along the wheel platforms.”

“The forward movement of the vehicle resulted in the front wheels of the vehicle dropping off the front of the hoist. The worker was crushed and trapped between the vehicle under carriage and the front cross beam of the hoist.” the regulator said.

Contributing factors

The safety regulator said the there were a number of contributing factors associated with the incident including (but not limited to):

  • Unsafe modifications to the hoist – removal of wheel stops
  • Poor maintenance and inspection – a number of serious safety issues were identified during inspection of the hoist by a competent person.
  • Unsafe work procedures – inadequate controls to prevent the vehicle from rolling while on the hoist.

Design of vehicle hoist contributes to incident

The Regulator has highlighted that the design of vehicle hoists require workers to position themselves directly under suspended vehicles to carry out mechanical work. It is crucial that all safety components are operational and fit for purpose to ensure worker safety.

Wheel stops are a safety component of the vehicle hoist involved in this workplace fatality. Wheel stops prevent a vehicle from rolling off the ends of the wheel platforms. Tragically the wheel stops were not fitted to the hoist when this incident occurred.

Regulator recommends a range of corrective actions on vehicle hoists

  • Ensure vehicle hoists are installed and commissioned by a competent person in accordance with manufacturer’s specifications.
  • Modifications or repairs must only be conducted by competent authorised persons and records must be kept.
  • Operators must inspect vehicle hoists for defects prior to use.
  • Conduct functional tests of safety components prior to working under suspended load.
  • Operate and maintain hoist in accordance with manufacturer instructions.
  • Arrange inspection by an independent competent person at least annually.
  • Provide adequate training, information, instruction and supervision to hoist operators.
  • Maintain records such as log book for hoist maintenance, inspection and use.
