of tipping vehicles with normal control is about 5 tons. It appears, however, that the need is showing itself for tippers of this type designed for a payload of 7 tons. Many of lower capacity are being seriously overloaded.
In this heavier class some models are available hut, with only one or two exceptions, they embody full forward control and herein lies a certain difficulty: According to well-known operators who have to employ such vehicles on difficult sites, much of the load is thrown onto the front wheels. This is of little consequence when a vehicle is laden, but having tipped its load, the rear wheels may then carry insufficient weight to give adequate drive under adverse conditions. Consequently, and not infrequently, agang of men may have to " bounce " the rear of the vehicle in order that it may obtain sufficient grip to move from the -point of tip. With normal drive, and more of the unladen weight at the back, such a contingency seldom arises.
It is quite understandable that vehicle manufacturer S already producing a considerable number of models may not be particularly enthusiastic at being asked to add another to them, but practical operators usually know what they want and those who wish to meet their.needs must obviously bear this in mind.
