Vehicle container unloader for use on sloping ground

摘要

The equipment has control systems to register the inclination of a container (2), and can lift it differentially and securely above the load- carrying surface (1) of a vehicle. The inclination of the loading or resting surface is maintained during the lifting operation, and the vehicle is then driven away from under the raised container. The load is lowered under control in the same attitude as it was in at the beginning of the lifting process, and is levelled when at least three of the supports (3.1,3.2) finally become unloaded. The use of the equipment on slopes of up to 4 degrees, is also discussed.
