Abstract: A power winch with changeable connection position includes a first connection line and an induction line connected between a power source and an electric control box, which are connected to a second connection line for grounding the electric control box, and a third connection line is connected to the power source for grounding. These lines are connected to the exterior of the electric control box and the power source to facilitate a quick detachment from the electric control box and the power source.

Abstract: In an integrated structure of a power source of a power winch and an electric control box, the electric control box of the power winch is integrally combined with the top of the power source by a support frame, and an outer cover is provided for axially covering the electric control box and the power source and locked and connected to a front shell wall, so that the electric control box and the power source are completely hidden in the outer cover without any exposure. In other words, the electric control box is combined with the power source by a hidden assembly mode, so that the electric control box can be securely assembled without any risk of being shaken or falling off. In the meantime, the electric control box is hidden in the outer cover, and thus it will not be affected by weather at all.

Abstract: An easily changeable assembly type power winch includes a power source, a deceleration device, an outer casing, a rope wheel, a first support frame and a second support frame. After the power winch and two cross plates are assembled to form a basic assembly, a rope outlet board and an electric control box are assembled with the basic assembly to form the power winch in a horizontal assembly mode or an upright assembly mode, and these two assembly modes can be switched quickly to achieve the effects of reducing the manufacturing cost, improving the convenience of assembling, and broadening the scope of application.

Abstract: In a release mechanism of a brake device used in a power transmission process, a motor supplies power, an output shaft of the motor is connected to the brake device, the brake device is formed by at least one friction disc and a brake disc, and a lining is installed on a side of the brake disc facing the friction disc, and a side is acted by an elastic member and attached with the friction disc to produce a braking effect. The release mechanism is connected to the brake device and capable of eliminating the braking effect of the brake device when needed, so that a machine can be operated to complete a stroke to improve the safety of use.

Abstract: A winch capable of externally connecting motor is to selectively assemble and increase an externally connected motor (a third motor) on a winch driven by a set of motors so that a driving device disposed inside a driving device box of the winch is driven by dynamic power supplied from three motor at the same time to provide greater pulling force and faster pulling rate for a rope wheel of the winch, thereby providing wider scope of application. Moreover, the externally connected motor (the third motor) can be disassembled when there is no need such that dynamic power is provided by two motors so as to save power and energy resource.

Abstract: A power winch for motor vehicles includes a display panel for displaying the operation status of the power winch and letting users know whether or not the power winch is situated at an electrical connection status for use, the voltage of a vehicle power supply connected to the power winch, whether or not the power winch is connected to the wireless handheld controller normally, and whether a steel wire rope of the power winch is wound or unwound, so as to improve the safety of operation, control, and use. The power winch further includes a storage holder installed on a surface of the power winch for storing the wireless handheld controller to facilitate a quick access or use of the wireless handheld controller, so as to improve the convenience of operation, control and use.

Abstract: A power winch overcurrent (overload) safety device includes a display panel with an overcurrent (overload) warning display zone. Simultaneously, amperages used in the power winch is set with an upper limit current setting value, and a current actual value is set for an actual amperage. The current setting value and the current actual value are displayed on the display panel. A first plug socket is plugged by a plug head of a controller to perform operating of the power winch, and a second plug socket is further disposed on the electrical control set of the power winch and connected to a circuit set for the current setting value in the electrical control set, and which using for the plug of a current regulator to regulate the current setting value.

Abstract: A cord protector is combined with a cord to protect the cord. An outermost end head of the cord would revolve and is fixedly connected to the cord through a collar. The cord protector is assembled by a first protection seat and a second protection seat. The first protection seat and the second protection seat are made of flexible material resisting impact. Openings at the bottom of the first protection seat and the second protection seat co-clamp the cord. A top portion of the first protection seat is divided into two through grooves by a cross bar. Two side cord bodies of a revolving combination place of the cord respectively enter the two through grooves of the first protection seat and are joined by joining members. With the composition, it prevents collision between combined rigid components to protect the combined rigid components and operating users, thereby increasing use safety.

Abstract: A pneumatic and manual clutch of a power winch provides an option of controlling the clutch by a manual or pneumatic method. The pneumatic control method just needs to connect a pump connector of an air pump to a pneumatic connector of the clutch properly to start or stop the air pump even when a user is standing at a position far from the power winch and the clutch can be turned on and off by starting or stopping the air pump. Either a cable or wireless remote control can be used to start or stop the air pump, to provide a very convenient operation.

Abstract: A power winch horizontal-push winch, and that the power winch includes a clutch, and an operating handle is turned to move transversely to push a clutch lever through a binding groove to apply or not to apply a force to an insert slot to transmit or not to transmit the power to the cable wheel. The operating handle can change the installation angle or remove/replace the operating handle anytime. The operating handle has a penetrating hole near an outer side for receiving an end hook of a rod-shaped object, and the operating handle may be linked to turn transversely by applying a force to the rod-shaped object.

Abstract: Disclosed is a torque limiting and conical braking assembly for a power winch. In the process of outputting power by a power supply and transmitting the power to a reduction mechanism, a torque limit mechanism formed by a torque shaft, a friction pad, a brake pad, a disc-shaped elastic element, an adjustable positioning ring and a positioning screw ring and a conical braking mechanism formed by a brake block, a disc-shaped rim, a wedge block and a bump are installed, so that when the reverse torque produced by the carrying load of the power winch exceeds the torque bearable by the power supply, the power transmission is cut off immediately and a conical braking effect is produced to protect the transmission mechanism from being damaged.
