摘要： An auxiliary brake assembly for use in a hoist, is disclosed. The auxiliary brake assembly comprises a pinion, a fastener, and a clutch assembly. The pinion may comprise a mesh gear disposed proximate a respective mesh gear of a rotor gear. The clutch assembly may be disposed between the fastener and the mesh gear. The fastener may be configured to compress the clutch assembly in the event a cable drum of the hoist is free spinning. The compression of the clutch may lock the pinion and the rotor gear and stop the cable drum from spinning freely.

摘要： A clutch comprising a pump is disclosed. The pump is operatively connected to the clutch such that a clutch slip event will cause the pump to delivery fluid from a fluid source to a region surrounding the friction plates of the clutch. The operation of the pump manages heat that is generated by the dynamic friction of the slipping clutch plates. The pump and associated fluid delivery methods are removably securable to an upstream end of an input shaft of the clutch. This allows the pump and associated fluid delivery methods to be used as modular components, that are easy to remove and replace for maintenance purposes, it also allows easier access to the internals of the clutch for maintenance.

摘要： A clutch assembly for a hoist may comprise a first epicyclic gear train and a first set of friction disks rotationally coupled to the first epicyclic gear train. A second set of friction disks may be in operable communication with the first set of friction disks. Torque may be transferred between the first set of friction disks and the second set of friction disks by means of a friction coupling between the first set of friction disks and the second set of friction disks. A pinion may be rotationally coupled to the second set of friction disks. A splined portion of the pinion may form an output of the clutch assembly.

摘要： A cable angle detection assembly is provided. The cable angle detection assembly may include a housing defining an axis configured to allow a cable to pass partially through the housing such that a first portion of the cable is aligned with the axis. The cable angle detection assembly may include a bracket rotatably disposed within the housing. The cable angle detection assembly may include a guide element mounted to the bracket configured to guide the cable, when in tension, to be wrapped partially therearound thereby allowing a fleet angle to be defined between the first portion of the cable and a second portion of the cable that extends tangentially away from the guide element.

摘要： A clutch comprises an input shaft, an output shaft, a biasing member and a plunger. The biasing member is arranged to provide a biasing force that allows torque transfer from the input shaft to the output shaft via one or more input friction plates and one or more output friction plates. Axial displacement of the plunger relative to the output shaft may cause the biasing force to vary to adjust the maximum torque setting of the clutch during reeling-in or reeling-out of a winch cable around a winch drum. A winch assembly may be provided that includes an arm in operable connection with a winch drum. The arm is displaced as the effective radius of the drum varies during reeling in or reeling out. Displacement of the arm can be communicated to the plunger to provide the axial displacement thereof.
