HOISTER FOR PREVENTING EXCESSIVE TENTION

摘要

The invention of the joist member is pulled with the cable or wire, in addition to the torque wrench to the handle of the joist group pulling a wire and so on, and the net while verify this, a proper tension, so as to idle when the maximum load is acting in tension device and that relates to a tension-proof coverings to prevent damage,; And a pair of National Sport University, The National Sport University pivotally mounted to the saw-tooth gear and the relatively small driving gear one of the large diameter to the outside of the National Sport University is axis-connected wire bobbin and the combined turning vain to the axis of the wire bobbin and the the drive gear in forward, reverse and neutral lever handle and selecting the possible redirection coupled key provided to the, ningham a is provided to the National Sport University applied releasably to the saw-tooth gear to prevent the loosening of the wire bobbin ratchet agent in groups comprising joists,; The handle end of the lever handle, a display portion and the control knob, and install the torque wrench to set the limits to the tension,; And the eastern consisting of a ratchet gear built-in disc brake to the wire beam frown be rotated is limited in one direction by the ratchet pawl assembly in the National Sport University,; And Lee Dong - kwan rotating part forming the surface in contact so that the one-way rotation to the wire beam frown screwed disc flange to one side of said first portion in one side,; And the lever handle is inserted in the outer peripheral surface portion provided with the rotation Lee Dong - kwan first lining and the idling direction changing lever Tangier while interposing a gear on the side of the intermediate flange on the disc, the control panel is assembled into the second lining net,; It formed thereby positioning the elastic member interposed elastic supporting the plurality of lining guide which is brought into contact with a second lining of the operating unit assembly configuration a spring cam, including parts of repression is fixed to the wire beam frown into a cam bolt through a washer and tension-proof jeongseongi there are excellent results to provide.
