Cable or chain conveyor, has motor output regulated by system comprising hinge fastener for driven wheel and output reducing control mechanism

摘要

Motor output is regulated by a system comprising a hinge fastener for the wheel (4) driven by this motor (5), the driven wheel being movable in the same plane as the wheel next to the output side of the cable or chain (14). The driven wheel is secured to the frame. The system also includes a control mechanism for reducing motor output when the driven wheel is being in moved in a direction opposite to the pay-out direction for the cable or chain. The cable or chain extends around at least two spaced apart pairs of wheels, at least one wheel in each pair being driven by a motor mounted in a frame.
