Review on 🔧 WARN 101575 Handheld Portable Drill Winch: 40 Ft Synthetic Rope, 750 lbs Pulling Capacity - Gray by Sean Maples

After reading some reviews I was concerned that this winch would be very slow but if you have a high torque, high RPM drill it is quite fast. The ratio of shaft revolutions to spool/drum revolutions is 77.6 to 1, so I was doing 41.9 spool/drum revolutions per minute with my 3250 rpm cordless drill. The drum is 1.79 inches in diameter when empty, which translates to a circumference of 5.625 inches or about 19.6 feet per minute when unloaded. Winding speed increases as the winding progresses because the cable being wound (which is 5/32nd of the diameter) increases the circumference of the drum by almost 1 inch for each complete layer of winding. So, using a drill at 3250 RPM with no load, the first 8.44 feet of tension on a fully extended line will have a feed rate of 19.62 feet per minute due to the larger drum/spool circumference; the next 9.91 feet will progress at 23.05 feet per minute and the last 11.38 feet at 26.47 feet per minute. Pretty fast for a winch powered by a drill. Of course, since there is no such thing as a free lunch in physics, the maximum pull force decreases by the same percentage as the speed increases. Thus, the pulling force decreases with each step around the circumference of the drum/spool. The first 8.44 feet will tow the rated top speed of 500 pounds; the next 9.91 feet will drag 17.5% less, or 412.72 pounds; the next 11.38 feet will drag 14.9% less, or 351.39 pounds. If you need to pull the load along the entire length of the rope, you must ensure that the load does not exceed the maximum allowable pulling force over the entire length of the pull. For example, you can load a 500 lb. pull for the first 8.44 ft., and then as the girth increases, the winch overload clutch shuts off the engine because that load exceeds the 412.72 lb. load limit. exceeds. So if I need to pull something that puts constant stress on the rope for the entire length of the rope (30 feet), I shouldn't exceed 350 pounds lest the load limiter shut off the motor when it reaches the limit. last 11.38 feet of thrust. I could always use a pull block to double all load values by halving the winch's maximum pull distance to 15 feet and halving its pull speed (FPM). As a general rule, if you plan to tow a permanent load on a fully extended single line no more than 8.4 feet, it should be no more than 500 pounds if you tow it over 8.4 feet, but no more than 18.3 feet , then the load should be no more than 413 lbs and if you are doing a full 30 foot cable pull you cannot exceed 350 lbs. Obviously pulling is different than vertical lifting. Depending on pitch and friction, this winch can easily pull a rolling object that weighs well over 500 pounds as long as that object does not put more than 500 pounds on the winch. Well, if you intend to ignore the manufacturer's warnings and use this winch as a vertical lift, then yes, a 500-pound object is the limit you can lift (and only 8.44 feet). Of course, your mileage may vary based on load weight, but I pull about half the rated weight horizontally on a rope for 20 feet, it only takes a minute to do the job, and the load limiter has never tripped since I've been that far below the maximum load limit for this distance. I don't know about you, but I can definitely take a minute not to use my muscles to pull 250 pounds in 20 feet.
