Machinery Safety & Hazard Guidance

Tip Truck Hoisting Systems

Tip Truck Hoisting Systems


Background: AS1418.8 – 2008 Cranes, hoists and special purpose appliances originated in 1989. It was revised in 2002 at which time section 5 – Requirements for Earthmoving Equipment, and section 6 – Side Boom Pipe Layers were added. The document was revised again in 2008.


Section 4 – Tip Truck Hoisting Systems was part of the original document.


It is our experience that the requirements set out in this section of the standard are very rarely all found on a machine. As a result we regularly receive questions regarding the requirement for load holding valves, safety props, emergency stops and hold to run controls on tippers
