THE TROUBLE WITH TIPPERS IS......

Tipping vehicles and their mechanisms are described by reference to the single-ram front-of-body tipper with three, four or five stage telescopic rams and the alternative twin-ram systems. The origins of failure of such mechanisms are related to the results of the examination of some 44 twin-ram failures over a period of several years - the very few single-ram failures observed occurred in circumstances where gross misuse or accidental circumstances were recognised. Tipping techniques are described both for tippers and bulk powder carriers, and information provided on the angle at which different materials will slide out of tipper and tanker bodies. Emphasis is placed on the manufacturers stipulation that tipping should be progressive and carried out on level sites. It is suggested that twin-ram tipping systems are more vulnerable to failure than their single-ram equivalent, mainly due to their lesser bending stiffness and the tendency for differential extension of the ram sections to cause one ram to destroy the other.
