I don''t dewalt know anything else nonexplosive, that you can pick up with one hand, and that can move five tons one hundred feet--with mini drill press safety, precision, and astonishingly little work. like many good tools the tirfor is a thing of beauty, superbly designed and engineered. with 100 feet of cable (or more) its reach is much greater than a come-along, and this can often make all the difference. its speed is much faster, too, not just the speed in moving something (the lever is double-acting) but speed in setting up press or moving the set-up around. often when you need to move something, minutes if not seconds count. the action is precise. a come-along winds the cable upon itself, and often when the dewalt cable comes under tension the cable wrap slips a bit. the resulting drill jerks can cause all kinds of problems in a situation where precise movement counts, and a sudden shift in load may cause failure somewhere else. finally, the tirfor has a much more effective (and safer) mechanism for smoothly lowering a heavy load. most (ratcheted) come-alongs are very poor at this.
