摘要： A modular lift assembly includes a frame, at least one head block connected to the frame, a drum rotatably connected to the frame about an axis of rotation and having at least one winding section, and a drive mechanism operatively connected to the drum for rotating the drum. In various examples, the lift assembly includes at least one loft block internal or external relative to the frame. The loft block is configured to guide a cable from the at least one head block to a load. The lift assembly can further include a load brake positioned along the axis of drum rotation to reduce risks associated with a drive or motor failure.

摘要： A lift assembly having a drum rotatably mounted to a frame and linearly translatable with respect to the frame. A plurality of head blocks are connected to the frame along a helical mounting path, wherein linear translation of the drum during takeoff or take-up maintains a predetermined fleet angle between a take off point from the drum and the head block.

摘要： Braking mechanism and a winch having the braking mechanism. The braking mechanism allows a winch with which it is associated to hold a load once the winch has dragged the load up an incline. The winch includes a motor, a drive shaft selectively driven in opposite rotative directions by the motor, a gearbox, a rotatable drum and a cable wrapped around the drum. The motor provides torque, which through the gearbox turns the drum of the winch. When the motor is stopped, and the load on the cable attempts to pull the cable back off the winch drum, the torque that is fed back from the drum into the gearbox and into the drive shaft engages the brake.

摘要： A brake for use with a shaft rotatably driven for raising a load and for automatically braking rotation of the shaft when the driving means is stopped or fails. Relatively shiftable camming members are employed to apply a frictional braking force against yieldable resistance and means is provided for creating a braking force that is not directly proportional to the amount of the load involved. In one form of the invention, a plurality of pairs of camming surfaces are provided; one pair cooperating to apply the braking force when the load is relatively light and an additional pair or pairs of camming surfaces are provided to resist heavier loads. By this structure, light loads are adequately held by a brake that is, of necessity, designed for relatively heavy loads. In addition, the instant load brake permits the brake to be easily released when the load is lowered without requiring excessive torque to effect such release thereby eliminating brake chatter and reducing wear and heat. The brake shoes of the load brake are urged against the opposite outwardly facing surfaces of a pair of brake plates which in turn are yieldably urged outwardly toward the brake shoes. In the preferred form of the invention, a cam follower is provided which cooperates with a camming surface which is formed to a progressively increasing slope as the angular displacement between the camming members increases, thus insuring easy release of the brake as well as adequate braking of the load regardless of the magnitude of the latter. An automatic adjustment device is also provided which insures that wear within the brake will be compensated for without affecting the behavior of the brake.
