Abstract: A wire clamp device affixed to an outer end of a bar in a wire tightener of the type having a stationary wire holding clamp at an opposite end of the bar. A carrier is mounted on the bar and is also provided with a wire holding clamp. The bar is provided with a jack rack and the carrier has a jack mechanism for forcibly driving the carrier toward the first wire holding clamp so as to pull end portions of two strands of wire held by the two wire holding clamps toward each other. The wire clamp device which also has a wire holding clamp is positioned to hold the strand held by the wire holding clamp of the carrier after it has been drawn towards the first wire holding clamp so that the wire holding clamp on the carrier may be released to allow the carrier to be reset to a position near the wire clamp device, after which the wire holding clamp on the carrier is again activated to grasp again the tightened strand which it had previously held.
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).
