Automatic control method, of tray angle in a tip-truck delivering gravel during road works, uses information on gravel, pouring requirements and speed of vehicle to control angle or tray or opening of doors

摘要

The gravel delivery is controlled by a computer which accepts information on the gravel being carried and the tipping rate required, and takes operating data such as road speed from the truck. The tipping rate is then indicated or regulated by adjusting the angle of the truck (2) tray (1) and/or opening of the delivery doors (3). A video camera (9) shows the gravel laid behind the truck. An Independent claim is also included for the gravel delivery machine.
