ABSTRACT:
A damped suspension system for conveyors which has a pair of shock absorbers each of which is associated with an initial stressed spring thereby exerting a balancing effect. In preferred embodiments the shock absorbers are provided with means comprising, for example, a casing and a sleeve wherein the cylinder is executing and up and down movement relative to the sleeve. Casing and sleeve each supporting one end of the spring during movement of the conveyer in a straight line. Since, during an inclination of the cabin of the conveyor, both ends of the spring located on the lower side of the cabin are supported only through the casing, there is no possibility of a releasing. Thereby at least the initial force of the spring located on the raised side of the cabin is effective for a reset of the cabin into its vertical position.
