High speed winch

  1. Jul 24, 2008 #1
    I am trying to figure out how to build a high speed winch. I need to be able to lift about 350lbs at a rate of 10 feet per second. I also need to be able to control the speed. I have power on site. I have been looking at a 3 hp 12 v dc motor and try to gear it to get the speed I need. Am I going the right direction?

    To lift 350lb at 10ft/s will require the use of at least a 6.4hp motor. At that power with 12V the current required will be at least 400AMPS. Sounds a bit impractical. Perhaps go for lower speed or higher voltage.

    Usually winches like this are hydraulic. Is that a possibility or is electric the only route available?

    I can only use electric for this project.
