A winch engagement apparatus that is configured to be operably coupled to a strap winch on a flatbed trailer wherein the present invention provides a technique to rotationally move the shaft on the strap winch so as to tighten a strap. The present invention includes a housing wherein the housing has a first side and a second side. A passage is present through the housing and extends between the first side and the second side having openings at each end thereof. The passage is configured to surroundably mount a portion of a shaft present on the strap winch. Engagement levers are present wherein the engagement levers are pivotally secured to the housing. The engagement levers includes a hole engagement edge that is operable to penetrate a hole formed on the shaft portion in order to operably lock the housing into position so a rotational force can be applied.

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 electric winch crank having a main body which includes an electric motor; a gripping handle arranged at one end of the main body and able to pivot on same with respect to the main body; a coupling means to a winch, arranged at the opposite end of the main body; a transmission mechanism driven by the output shaft of the motor and enables rotation of the coupling means; a mechanical reducer interposed between the output shaft of the motor and the coupling means, the crank further comprising a braking system mounted on the output shaft of the motor; a control member located on the gripping handle for actuating the braking system via the electronic circuit and a rotating collector having a first portion rigidly attached to the gripping handle, connected to the control member, and a second portion rigidly attached to the main body and electrically connected to an electronic circuit.

The invention relates to a crank arrangement (100) for operating e.g. a winch comprising an elongate crank arm (10), a hollow driving head (29) comprising an external engagement profile, a handle part (40) and a locking plate (25) arranged at an outer end of an actuator element rotatably taken up within the hollow driving head (29). Hinged lever arms (11 A, 11B) extend in parallel on external opposite side walls of the crank arm (10) and comprise protruding means (18A,18B) for, when at least one hinged lever arm (1 A, 111B) is gripped, actuating upon the actuator element rotationally connected to the locking plate (25) such that the locking plate (25) will perform a rotational movement to assume a first position in which the locking plate (25) is aligned with the engagement profile of the driving head (29), whereas when the at least one hinged lever arm (1 A,111B) is released, the locking plate (25) will be rotated to assume a second, locking, position in which it is misaligned with the engagement profile (30) of the driving head (29), means limiting the rotational movement of the actuator element being provided. The locking plate (25) can be rotated to assume the first position via a one-hand grip.

A winch handle (10, 20) locking system comprising a winch handle (10, 20) with a bit (11, 22) adapted to mate with a socket (11, 12) in a winch (10). The bit (11, 22) employs a first magnetic member, a magnet guide (23), interacting with a second magnetic element, a permanent magnet (12), inside the socket (11, 12). The magnet is fixed to the winch (10) at a position allowing the winch handle bit (22) to mate with the socket (11, 12) and securing a desired attraction force between the winch (10) and the winch handle (10, 20). Furthermore, a magnetic sensor (25) is placed at the magnet guide (23) in the bit (11, 22) and sends a trigger signal to electronics in the winch handle (10, 20) when the bit (11, 22) is fully mated into the socket (11, 12). An NFC antenna (24) in the bit (11, 22) is tuned to pick up a unique signal from an NFC tag (14) inside the socket (11, 12) of the winch (10) to allow the electronics in the winch handle (10, 20) to uniquely control a motor connected to the winch (10).
