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).
