Abstract

1365655 Winches HARNISCHFEGER CORP 14 Feb 1973 [24 Feb 1972] 7357/73 Heading B8B A crane winch comprises a drum 44 driven by a reversible hydraulic motor 34 which is interlinked with a spring operated hydraulically released brake 80, such that when winch lowering is normally selected the brake is first released followed by motor energization, when neutral is then selected the motor is de-energized followed by application of the brake and when winch hoisting is selected the motor is reversibly energized, lost motion linkage permitting the brake to remain applied, but a uni-directional clutch 74 allowing the brake to be over-ridden in this direction. The clutch 74 acts between the output shaft 36 of the motor 34 and a brake disc 72 engageable by discs 78 of the brake 80, which is controlled by a two position spool valve in circuit with the brake cylinder, a pump for the brake fluid and reservoir. The motor 34, which drives the drum 44 through shafts 36, 38 and planetary gearing 50, is controlled by a three position selector spool valve in circuit with the motor 34, a motor pump and reservoir. The degree of displacement of the motor spool valve varies the speed of the motor.
