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).

Abstract: A portable hoist or puller has two facing half shell members housing a chain sprocket rotatably affixed to a drive shaft supported for rotation by a pair of rollers. The first roller is slidably fixed for rotation with the drive shaft while the second is threaded to the shaft. The periphery of the threaded roller is serrated for engagement by a spring detent to inhibit its free rotation. Each roller has a hub portion extending outwardly of the housing to selectively receive a drive tool. A friction disc is disposed between each of the rollers and adjacent housing portion. To apply force to a load connected to the chain trained over the sprocket, the drive tool is coupled to the first roller and rotated causing the sprocket to feed the chain with the rollers pulled against the sprocket. If the drive tool released, the pull of the load tends to reversely rotate the shaft whereby the threaded arrangement causes the rollers to lock-up against the housing.
