A winch including a drive motor, a cable drum, and a gear train assembly coupled to the drive motor and including a planetary gear set having a ring gear positioned in a gear train housing. The gear train housing including a radial clutch mount and an axial clutch mount. A clutch mechanism is selectively positionable at the radial clutch mount, in a first configuration, and the axial clutch mount, in a second configuration. The clutch mechanism is operable to selectively lock and unlock the ring gear to the gear train housing, thereby engaging and disengaging the cable drum from the gear train assembly.

An actuating device is provided for a manually actuatable winch for operating a line. A first end of an actuating lever is configured for interaction with the winch, and the actuating lever is substantially elongate. A line deflection element is mounted on the actuating lever at a predeterminable distance from the first end of the actuating lever. Here, the actuating lever is connected to a resetting device by means of which a predeterminable force is exerted in a predeterminable direction on the actuating lever. A winch may be provided with the actuating device interconnected therewith.

A portable winch and method of use is shown. One advantage of winches shown includes an ability to lower a boom or boom sections into limited access exit pit for winching operations such as pipe bursting. Sectional boom designs shown provide the ability to easily raise and lower a boom large distances without the need for a single long boom. Selected winch designs shown include flexible inserts between the boom and the winch frame that help resist damage from unforeseen shifting of the device during operation. Designs and methods shown also include multiple pulleys on a boom end unit. Fasteners are shown that reduce build up of debris.

A control system for a rescue hoist attached to an aircraft is disclosed. In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; and a second bus extending between the control module of the rescue hoist and the control input device. The first bus is configured to transmit a first signal from the control input device to the control module and the second bus is configured to transmit a second signal from the control input device to the control module, both the first signal and the second signal being generated by the control input device in response to a manipulation of the control input device.

The invention relates to an electric winch crank (1) comprising a main body (3) which includes an electric motor (32); a gripping handle (2) arranged at one end of the main body (3) and able to pivot on same with respect to said main body (3); coupling means (4) to a winch (100), arranged at the opposite end of said main body (3); a transmission mechanism driven by the output shaft of the motor (32) and enabling rotation of the coupling means (4); a mechanical reducer (34) interposed between the output shaft of the motor (32) and the coupling means (4), said crank further comprising a braking system (35) mounted on the output shaft of the motor (32); a control member (23) located on said gripping handle (2) for actuating said braking system (35) via said electronic circuit (31) and a rotating collector (29) comprising a first portion (291) rigidly attached to the gripping handle, connected to said control member, and a second portion (292) rigidly attached to the main body electrically connected to an electronic circuit.

A handheld device is adapted to ascend and descend a cable. The handheld device includes a motor that is mechanically coupled to a gearbox shaft. A drive shaft is connected to the gearbox shaft with shaft drive bearings. A first housing is mechanically coupled to the motor and surrounding the drive shaft. The housing further includes a top side, a bottom side and at least one other side therebetween. A top housing opening and a side housing opening are arranged on the first housing. A cinch brake assembly, connected to the first housing. The cable is fed through the first housing, around the drive shaft, out of the first housing and through the cinch brake assembly such that the cinch brake assembly prevents movement of the cable through the first housing.

A slide-out room system includes a motor-driven sheath with wound cables for extending and retracting the slide-out room. The cables and the sheath are configured such that rotation of the sheath in one direction displaces the cables to extend the room and such that rotation of the sheath in an opposite direction displaces the cables to retract the room.

A fender davit device is disclosed. The fender davit device in accordance with an aspect of the present disclosure includes a fender and a davit comprising a hauling line holding the fender and a winch configured to move the fender by winding or unwinding the hauling line. The fender davit device also includes a hauling line tension maintaining part configured to maintain a tension of the hauling line holding the fender to prevent the hauling line from breaking.

A lift system comprises a drum that rotates about an axis, an elongate member that winds around the drum when the drum rotates in a first direction and that unwinds from the drum when the drum rotates in a second direction, a drive mechanism operable to rotate the drum, and a braking mechanism adapted to inhibit rotation of the drum. The braking mechanism includes a brake disk rotatable with the drum, a movable brake pad, and a ramp that guides movement of the movable brake pad. A method of operating the lift system comprises rotating the drum in a first direction to wind the elongate member onto the drum, rotating the drum in a second direction to unwind the elongate member from the drum, and moving the brake shoe along the ramp to thereby cause the movable brake pad to be compressed against the brake disk.
