Yesterday I passed a mechanic under the raised back of a large tipper truck that was full of soil. I did not notice a prop of any sort. Are these designed into the mechanism? Not a work issue for me, just for my own knowledge.

Some years ago I dealt with a client who had two workers crushed to death by working under unpropped tippers within 18 months. The first was his own lorry driver attempting an unauthorised repair on the side of a motorway. The second was a contractor's driver on a construction site earthmover who reported a fault with his tipper and then went missing. He was later found under the tipper. 'Nuff said?

Morning,

Although modern rams are designed not to fail, there is a chance of this due to pneuamtic failure, fluid leaks, electrical failure etc. etc.

Some tipper bodies do come with a built in prop however if you are repairing / servicing someone elses truck how can you ensure that these are o.k.? Especially with tippers who work in rough terrain like on quarries etc.

Our procedure is to empty the load first if possible and then secure the body with 2 tipper props. These are available from one of the UK's biggest tipper body manufacturers (other suppliers are available) and hence are specifically designed for the job. If the body cannot be emptied then you need to ensure the load is less than the SWL of the prop (s) See link:

We treat these as a Loler item and hence, due to the safety critical nature, these are tested every 6 months. Having spoke to the other main truck dealers this seems to be industry standard practice.

HSE guidance (INDG434) is to always use a body prop where there is not one fitted and these specific props are photgraphed in the guidance document, so you can't go far wrong going for these.

Don't forget tilted cabs which should also be propped if they can't be opened and locked fully. This causes more fatalities and major injuries in the Motor Vehicle Repair industry.

Best Regards
Ian
