A modular powered hoist design comprises: 1) a multifunctional baseplate, which forms a foundation of the powered hoist design and comprises part of a guide system for a lifting media, and 2) an integrated lift/guide assembly, securing a liftwheel therein, that is attachable to the baseplate through attachment features formed within the baseplate. Embodiments allow for different components of a powered hoist to be interchanged in the case of material incompatibility or to provide higher guide performance (such as accommodating different safety factors). Moreover, in manufacturing, embodiments allow for the use of overlapping product parts across different powered hoist product designs, thereby reducing overhead-related costs.

A heavy equipment recovery winch system includes a winch assembly mountable to a drive end of a heavy equipment vehicle, a hydraulic assembly and a fairlead assembly. The hydraulic assembly is mounted to a portion of the heavy equipment vehicle and the hydraulic assembly is operatively connected to the winch assembly. The fairlead assembly is mountable to the drive end of the heavy equipment vehicle to assist with guiding a cable from the winch assembly.

A winch includes a coupling A, a coupling B, a rectangular spring, a gear wheel, a gear rack, a friction ring, and a transmission shaft, etc. By increasing the distance between the adjacent internal teeth of the two-stage planet carrier, it ensures that the three-stage sun gear can be smoothly inserted into the two-stage planet carrier even if the elasticity of spring A is reduced, such that the engagement width between the three-stage sun gear and the two-stage planet carrier can reach the normal requirements. With the design of sliding gear ring and spring C, it can greatly reduce the phenomenon of mis-engagement when the external teeth of the three-stage sun gear enter the internal teeth spacing of the two-stage planet carrier, protect the teeth integrity of the three-stage sun gear and the two-stage planet carrier.

The invention relates to a drive device (1) for the spool (6) of a winch. The drive device (1) comprises a drive motor (2) having a drive shaft (5), a transmission (3) and an output shaft (4) that drives a spool (6). The transmission has a first drive connection (10) between the drive shaft (5) of the drive motor (2) and the output shaft (4) to the spool (6). The first drive connection (10) drives the output shaft (4) over a first rotational speed range (DB1) in a first gear. According to the invention, a second drive connection (30) is provided between the drive motor (2) and the output shaft (4), wherein the second drive connection (30) drives the output shaft (4) over a second rotational speed range (DB2) in a second gear. The second drive connection (30) is designed to be separate from the first drive connection (10) as a parallel drive path, and is driven by the drive motor (2) together with the first drive connection (10). If the output shaft (4) is driven by the second drive connection (30), the power flow of the first drive connection (10) from the drive shaft (5) to the output shaft (4) is interrupted.

A vehicle winch mechanism includes a drum, a motor and transmission, at least one drum and motor side support, at least one battery, and a motive trickle charge mechanism. The drum pays out and takes in a line. The motor and transmission drive the drum. The side supports couple the drum, the motor, or both to the vehicle. The battery provides power to the motor. The motive trickle charge mechanism charges the battery. In one embodiment, the motive trickle charge mechanism includes a permanent magnet, an enclosure housing the magnet, and two or more sets of conductive coils wrapped around the enclosure and electrically coupled to the battery. The enclosure houses the magnet such that the magnet freely moves and changes orientation within the enclosure. The coils of an individual set of coils are aligned along parallel planes, and the coils of separate sets are aligned along intersecting planes.

A method and system for storing items using a hitch adapter secured to a trolley that moves along a vertically oriented track is disclosed. In one embodiment, a winch raises and lowers the trolley and hitch adapter by retracting and deploying a cable that is secured to the trolley. A bicycle carrier may be secured to the hitch adapter for storing bicycles, and for raising bicycles when not in use.

A control device that controls an electric hoisting machine includes: a tension sensor that detects tension of a pulling member; a mode input unit that inputs a mode switch signal to switch between a winding mode and an unwinding mode; and a control unit that controls the operation of a electric motor. The control unit, when set in the unwinding mode, controls the electric motor in accordance with a detection signal from the tension sensor to cause the rotating body to be inversely rotated when the tension of the pulling member is not less than a predetermined threshold value, and to prevent the rotating body from being inversely rotated when the tension of the pulling member is lower than the predetermined threshold value.
