Abstract

The tipping mechanism consists of a stop which has a guide slot in its cam component, and which is attached so as to swivel on the chassis. The stop is connected to the piston of a control valve operated by a lever. A further lever is linked to the vehicle body, to which a cam follower is attached and is spring-loaded into such a position that it is in contact with the cam component. An arm is attached to the piston rod of the cylinder having an adjustable bolt which is so arranged that the lever is tipped upwards against the operation of the spring, when the cylinder is extended.
