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 power winch overcurrent (overload) safety device is that a display panel further comprises 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, and the current setting value and the current actual value are displayed on the display panel. 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. With the overcurrent (overload) safety device, an operating person can clearly know whether or not towed load is close to overload, and in case of overload shutdown condition, it can be resolved by regulating the current setting value.

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.

Abstract: Disclosed is a torque limiter for a power winch, and a torque limit mechanism is installed for timely cut off the power transmission whenever the reverse torque generated by a carrying load exceeds a torque bearable by the power supply during a power transmission process for transmitting the power outputted from a power supply to a reduction mechanism through a long shaft, so as to prevent the power supply from being damaged by overload. The torque limit mechanism is formed by a torsion shaft, a friction plate, a brake pad, a disc-shaped elastic member, an adjustable positioning ring and a positioning screw ring.

Abstract: An electric car jack includes a spindle, a second middle gear, an elastic ring, an upper lining, a third middle gear, a lower lining, an adjusting and positioning ring and a positioning screw ring that jointly form a torque limiting mechanism with a torque limitation effect and a positioning plate, a power gear, a brake disc, a disc tray, an output shaft and a latching member that jointly form a powerless brake mechanism with a ratcheted braking effect. Both torque limiting mechanism and powerless brake mechanism are compatibly installed in a reduction gear of the machinery part f the electric car jack to maximize their effects.

Abstract: A power winch horizontal-pull clutch device provides dynamic forces from a power source and uses a deceleration device to retard the force transmission to a cable pulley for releasing and rewinding a steel cable on the cable pulley. A connecting slot is formed on a casing of the deceleration device. The deceleration device includes an outer ring body and at least one insert slot formed on an external surface. The power winch includes a clutch device for selectively fixing the connecting slot to the insert slot to transmit the dynamic force from the deceleration device to the cable pulley. The clutch device is a sealed assembly and a control handle is provided for making a horizontal movement to achieve the clutching effect and prevent water, dust or other foreign matters from entering into the clutch device, damaging components, causing failure or malfunction, or clamping an operator's hand or foreign matters.
