These "hoists" are not running the 12 volt DC motors used in atv winches; they have 120 volt AC motors. But thanks for pointing out the obvious. I might have missed that fact if you hadn't pointed it out.
Actually, the pulley does not double it's torque rating. Whether you lift 440 lbs in single part or 880 lbs in two part line, the motor sees the exact same load.
Hey, if feel confortable pushing that thing to it's limit, then go ahead; it's your life, not mine. I never said that it CAN'T lift anything, I said I wouldn't TRUST it to lift anything.
I've seen a 2 ton electric hoist literally blow apart. The motor mounting bolts snapped and the motor flew right off the side. The almost 2 ton steel bar on the hook started freewheeling down and by the time the guy on the control reacted to all this and let go of the button, there was too much momentum and when the brake came on, the hook holding the load snapped. The 50 foot long steel bar fell down through the building 10 floors before it hit concrete. It punched a hole through 4 concrete floors before it finally stopped.
That was a high quality, japanese made, purpose built hoist that was lifting the rated load. How much faith do you have in the build quality of that chinese made hunk of junk ? What happens if you are pulling out an engine and a bolt snags ? Now all of a sudden you've gone from lifting within capacity to overloading the hoist by 20 or 30 percent, maybe more. Still trust the quality of powerfist tools ?
You want to school me on motorcycles ? Go ahead, I'm new to this and have plenty to learn. But do you REALLY want to argue about electric hoists and lifting with a Hoisting Engineer ?
