There have been several incidents where workers have suffered fatal or serious injuries when carrying out inspections or undertaking maintenance/repair work underneath raised tipping or tilting trays on trucks and trailers.

Truck Tipping and Tilting Trays

Tipper safety bar

Possible causes

  • this item of plant has the potential to suffer mechanical failure, slow leaks of the hydraulic lifting system, or inadvertent activation of the valve/control system which can cause the tipper tray to fall.

Action required

  • all work must be carried out by a competent person
  • never carry out any work or inspection between a raised tipper and the vehicle chassis rails, unless the raised tray is supported by a safety bar correctly applied or the tipper is supported by mechanically designed props or stands. Do not use wood to support the tipper
  • ensure that a safe system of work is developed and implemented prior to the work being undertaken to minimise the need for a person to be working under a tipper tray
  • ensure that limiter cables are protected from inadvertent activation by the use of shrouds or guarding
  • ensure that controls for the raising and lowering of the tipper tray are clearly marked and protected from inadvertent operation
  • never rely on the lifting equipment, cylinders or valves to support the tray in a raised position
  • carry out regular inspection and maintenance of the hydraulics and mechanical parts. Ensure that any worn or damaged parts are repaired or replaced.
