Much of the recent interest in tipping stab ity has been generated by the decision of construction materials giant Lafarge Aggregates to introduce 30 new &kill, tippers into its haulage fleet. However, part of the tender process, trailer manui turers bidding for the order had to show products met the IRTE Class A standar( tipper safety at a stability "shoot-out" he on the tilt-table at the Qinetiq test track ii Surrey last year. While all three contend Wilcox, Stas and General Trailers all the Class A standard, the order eventuE went to Wilcox. But why tilt test to the IF standard in the first place?
According to Lafarge's national trans' manager (Readymix) Nick Elliot explair "Basically the absence of other benchmarks, which are known by the industry accepted by manufacturers, meant the was only one option.
We believed it was important to have recognised standard or specification to aim for; something that was repeatable different tests." However he adds, "We concluded that 7° was an ideal maximu point, in addition, it is our belief that a tip leaning further than 7° of side tilt is beyo limits of safe practice."
