  • Publication number: 20140008591
    Abstract: An apparatus for applying tension to flexible items, including wire, barbed wire, cable, or rope, are described herein. A stationary clamping member is fixedly attached to a first end of a guide bar, extending outwardly therefrom, while a non-stationary clamping member is movably mounted to the guide bar. The first flexible item is secured in the stationary clamping member, while the second flexible item is secured in the non-stationary clamping member. A tensioning assembly, such as a ratchet-like assembly engaging notches in the guide bar, is adapted to move the non-stationary clamping member away from the stationary clamping member, thereby tensioning one or both flexible items. Once the flexible items have been tensioned, they can be connected together while under tension.

  • Patent number: 8528379
    Abstract: An apparatus and method for applying tension to flexible items, including wire, barbed wire, cable, or rope, are described herein. A stationary clamping member is fixedly attached to a first end of a guide bar, extending outwardly therefrom, while a non-stationary clamping member is movably mounted to and extending outward from the guide bar substantially parallel to the stationary clamping member. The free end of a first flexible item is secured in the stationary clamping member, while the free end of a second flexible item is secured in the non-stationary clamping member. A tensioning assembly, such as a ratchet-like assembly engaging notches in the guide bar, is used to move the non-stationary clamping member away from the stationary clamping member, thereby tensioning one or both flexible items. Once the flexible items have been tensioned, they can be twisted together to form a connection without losing tension.

  • Publication number: 20130112929
    Abstract: The present invention discloses a chain load binder in the field of mechanics, which addresses the problem existing in conventional load binders for which larger goods could not be reliably bound by ropes such as ribbons. The chain load binder of the present invention comprises a body, a handle, a tooth stop plate, a catch, a chain and a rotation shaft. The body is linked with a first hook. A spring is provided between the tooth stop plate and the body, which tends to press the tooth stop plate against the ratchet wheel. A positioning member is further provided at the body. The two ends of the spring can act against the positioning member and the tooth stop plate respectively. The positioning member is separate from the body, so that both the body and the positioning member can be easily processed.

  • Patent number: 8424846
    Abstract: An overload warning system for a winch hoist of the type that includes a drum that rotates about a drum shaft, a handle that is received in a socket, wherein the handle can be used to turn the drum, and a movable frame that is located between the socket and the housing. The socket is coupled to the drum shaft. There is a shear pin with one end embedded in the frame and the other end embedded in the socket, the shear pin defining a relatively weak shear zone located between the frame and the socket. There is an elongated opening defined in the socket and a projection projecting from the frame and into or through the elongated opening. If the shear pin fails under rotational load applied through the handle, the socket will rotate relative to the frame until the edge of the elongated opening contacts the projection. The socket movement provides tactile feedback that the shear pin has failed, while maintaining control over the hoist operation via the handle.

  • Patent number: 8152139
    Abstract: There is disclosed a load binder device (10) for tightening, a load, for example during transport on a truck. The device is connected to hooks (80, 102) for securement to suitable anchor points and has an actuating lever (20) and lashing wheels 40. The actuating lever includes a pushing plate (32) which engages ratchet teeth (41) of the lashing wheels to rotate them. A stop plate (56) engages with the ratchet teeth and allows the lashing wheels to be rotated to tighten the load but prevents the wheels from rotating in an opposite direction to release the load. The actuating lever can be released from the lashing wheels by lifting the pushing plate and can be moved into an unlocking position in which cam-like lobes (24), forming part of the lever, force the locking plate into a disengagement position for releasing the lashing wheels to allow the load to be released.

  • Publication number: 20030111650
    Abstract: The invention relates to a tension ratchet with a belt magazine, for rapidly fixing a good to be transported to a vehicle, an object to a support, or several objects to each other. The tension ratchet (30) is combined with a belt magazine (1) which receives the entire idle belt supply during use and during storage and ensures rapid tying down/releasing of e.g. a transport load, due to constant availability for use; as well as tidy storage. The belt magazine (1) is arranged in such a way that it lies flat on the lower arm of the tension ratchet (30) in order to reduce the construction height, with a vertical belt winding up shaft (15) for receiving a belt to be wound up in horizontal rotation. The belt runs into the tension ratchet out of the belt magazine on its back side in the winding position, rotates about 90° in said tension ratchet and is then led out through the load tensioning roller (8).

    Abstract: A rope pulling device includes a come-along (20) having a frame (30) on which are mounted an anchor end grip assembly (200) and a load end grip assembly (300). During operation, the anchor end grip assembly is locked on the rope. A hook (100) is carried on the spindle (62) of the ratchet assembly (60). A lever assembly (50) drives a pawl assembly (80) which rotates the ratchet assembly in the forward direction. The hook causes rope to move through the unlocked load end grip assembly and to wind about the spindle. When the spindle is full, the load end grip assembly is locked. A lock assembly (70), which prevents counter-rotation of the spindle is released, allowing the spindle to be reversed and emptied. Slack rope is then passed around the hook, and wound about the spindle for approximately two turns. The load end grip assembly may then be released and the spindle may again be filled with rope, thereby pulling the load (400) closer to the anchor (500).
