An apparatus serves to grip a cable for delivery into a borehole in a surface of a mine passage in connection with an actuator, such as a drill mast having a carriage capable of being advanced and retracted along the drill mast. A pusher is formed from a pair of jaws for engaging the cable. The jaws may be biased toward a first position for engaging the cable during an advance of the carriage, and automatically movable to a second position for releasing from engagement with the cable during a retraction of the carriage. The pusher may be pivotally mounted to a carriage capable of being advanced and retracted along a drill mast, which movement may cause the jaws to self-actuate for engaging and advancing the cable during an upstroke and release therefrom during a downstroke. Related methods are also disclosed.

A portable pulling device and method therefore, the portable pulling device including a chassis frame, a power source, anchoring elements, a spool, a rope or cable attached thereon, and a centrifugal clutch with a chain or belt drive system allowing the ability to pull out the rope when the power source is at idle. The device further contains frame propulsion components such as wheels, skis, or tracks to facilitate movement of the pulling device into and through a confined area such as a forest or a barren area.

A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a composite cable having a high-performance termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

A miniature handheld electric traction device including a shell, a power supply part, a power motor, a reduction gear set, a braking part and a winding drum, wherein the power motor, the reduction gear set and the winding drum are arranged in the shell; the power motor is linked with the winding drum through the reduction gear set; a surface of the winding drum is wound with a traction rope; the reduction gear set includes a planetary gear; the sun gear of the planetary gear is coaxial with the winding drum; the power motor or the motor shaft of the power motor is inserted into the inner ring of the winding drum; the motor shaft is linked with the planetary gear.

A skate drive system for a catwalk having a skate and a clamping assembly. The system includes a primary actuator and a secondary actuator. The primary actuator is configured to apply a drive force to first and second cables to move the skate along a trough of the catwalk. The secondary actuator is configured to apply a tension force to at least one of the first and second cables independent of the primary actuator to actuate the clamping assembly from an unclamped position to a clamped position.

A hunted game winching assembly for drawing hunted game through uneven area includes a winch has a cable is wrapped therearound when the winch is turned on to rotate in a first direction. The cable is drawn off of the winch when the winch is urged to rotate in a second direction. A harness is releasably coupled to the cable and the harness is positionable around hunted game. In this way the winch can draw the hunted game toward the winch when the winch is turned on the rotate in the first direction. A pair of handles is each of the handles is coupled to and extends in opposite directions from the winch. Each of the handles can be gripped to positioned the winch between a user and the hunted game.

A locking strap system including: a locking strap assembly having a retracting and winding device with a main body, a winding shaft rotatably mounted on the main body, the winding shaft able to wind, in series, a length of webbed strapping, the webbed strapping able to be wound and alternately retracted sequentially based upon forces imparted on it wherein the webbed strapping when released is wound around the winding shaft via springs, a ratchet wheel which is rotatably mounted on the winding shaft, a pawl for selective engagement with the ratchet wheel for causing the springs to reduce a torque exerted to the winding shaft and hence reduce a retracting the force exerted to the webbed strapping, and wherein the locking strap system is configured to provide a safe means to secure a rollable object to prevent uncontrolled relative movement; the webbed strapping removably couplable to the rollable object.

The invention is directed to portable winch systems comprising a winch that is powered by a rechargeable first power source operably connected to the winch and a second power source operably connected to the rechargeable first power source and/or the winch. In certain embodiments, the system comprises a frame and/or housing to which one or more of the winch system components is mounted. In some embodiments, the portable winch system comprises a mechanism to mount the system to a hitch receiver of a vehicle or other object and/or mechanisms for transporting the system, such as casters and/or handles.

A mobile winching system is provided, whereby a preferred embodiment describes a motorized winch and power source mounted on a small frame that includes wheels, a handle, and a means for securing the winch system during operation. This mobile winch system provides a way to transport and operate a winch in areas that are otherwise inaccessible by traditional vehicle mounted winches.

An electrically propelled towing apparatus includes a housing, in the housing being provided a reel, a stator, and a rotor configured to drive the reel; a mounting cavity is defined in the housing; and the stator is exposed and fixed in the mounting cavity. With elimination of the conventional housing of drive motor, the invention improves heat-dissipation effect.
