  • Cheap winch/power transmission ideas

    I'd like to build a lift table to raise lawn mowers and snowthrowers to a good working height. I've sketched out a few ideas, using a die lifting table as a design, but mine will be significantly lighter duty (like 200lbs max capacity). I just want something that can do the awkward lifting that is tough to do alone.

    However, I need a power source to raise the table. die-lifting tables ive seen have airbags, which are pricey, so are hydraulic or pneumatic actuators. I thought of getting an electric winch from Harbor Freight, but they're all 12 volt, so i'd need a transformer.

    Another idea is a gear reduced, reversible motor with a length of acme threaded rod, but i dont know where to find a cheap motor like that.

    I was wondering if anyone had an idea for cheap power transmission in an application like this

    How about a auto floor jack or bottle jack. Both under $25.00

      Bottle jack is a good idea mcskipper, but its overkill and it would take alot of pumping to raise the table.

      I take a lawnmower on/off a table about 15 or more times a day, to test start it and so on. I was trying to think of a rapid, relatively low power source that could push the table up or down in a few seconds

        Why not start with a Harbor Frieght motorcycle lift?

          jack

          Sir,

          How about some sort of scissors/platform arrangment with an air cylinder and some sort of quarter-turn valve(s) for letting the air in and out??? It should be fast and easy to do.

          Regards,

            What about a hand winch something like this one: http://www.northerntool.com/shop/too...5596_200395596

              Check HF or some other cheap outlet for hydraulic log splitter and rip the hydraulics from that. In here I can get one for 200 EUR (incl. 23 % VAT, so without tax that is like 200 USD). This way you get electric motor, the hydraulic pump, hydraulic valve and a long stroke piston (1000 mm seems to be common) with 5-6 tons of force.
              Amount of experience is in direct proportion to the value of broken equipment.

                For only 200 lbs I'd be thinking low tech; along the lines of a block and tackle system. From floor to waist high we're talking 3 or 4 seconds, and moving less than 5 ft of rope.

                Assuming you have a suitable overhead attachment point of course.

                  You could incorporate the B&T into the lift along with a crank to take up the rope. The typical hunter's B&T is usually a 500# cap so that may just do the trick.

                    Years ago, I built an elevator for a friend's beach house so he could get upstairs in his wheelchair without assistance. I used 4" PVC pipe with a plastic piston inside to lift the platform nine feet from the ground to the raised deck.

                    The power was supplied by the city water system by opening a valve to fill the cylinder. Another valve drained the cylinder when he wanted to come down. The waste water was piped to a sprinkler in the yard.

                    I used a counterweight on a cable to balance the weight of the platform, so only the live load (about 200 pounds) was moved by the cylinder. The platform was cantilevered off a frame with boat trailer rollers that ran up and down a stout wooden beam.

                      Why not some threaded rod and a half inch variable speed power drill?
                      I bet you already own the drill.

                        Enco has Acme threaded rod (3' length) and nuts for reasonable cost.

                          If you can find an old bumper car jack that will give you plenty of lift, a very old VW jack had a long threaded rod and a little right angle gearbox at the top for the handle.

                              Possibly a simple ramp up one side and down off the other.??

                              Dunno, but just a thought.
