Wood elevator

[chuck172]

I'd like to build a plateform operated by an electric winch to raise loads of firewood and/or groceries up my deck.
The deck is 6' high. My wife wants a button not a crank, so no genie lift.
Anyone have any plans for this?

Sir
Always go with the wifes idea, electric button. A 120 volt winch could supply the power to lift a homemade frame, as long as it is not used to transport a human. Then it is a human elevator and you do not want to go there. The only problem with a winch could be cable snags. Electric chain hoist will stand up much better, electric actuator could work if you can multiply the stroke. The frame should be capable of holding 500 LBS. Check wheel chair lift platforms and go from there.

Hi Chuck,

I built just such a thing last year for a buddy who was recuperating from an accident and needed a way to get up into his house without climbing stairs. Below are three pictures. but they don't show much detail. As it happens I was planning to take more detailed pics soon, so I'll try to do that this weekend and post more.

Basically it is a diamond plate platform with triangular frames on each side. Pairs of roller bearing dolly wheels are mounted top and bottom on both sides. These ride in tracks made of two pieces of 1x2 channel welded together to make an "H" shaped track. This way the platform is captive and precisely located on the tracks. An electric winch does the lifting, with the cable running up to a block visible on the left top of the second picture, then back down to an anchor near the winch. This gives a 2:1 reduction. A cable leads from an eye bolt at the top of each triangle frame, then up and over pulleys mounted in the top frame, where they connect together at the 2:1 block.

There are several other nifty details that I need pictures to explain. Everything was spec'd for about 1800 lb. capacity. It has worked great from the start - my friend never carries anything heavy up stairs anymore.

Very nice spurlocktool. Gives me lots of ideas.

Check with forklift dealers. You can sometimes get masts from light duty forklifts & electric hydraulic pump & controls for pretty cheap money. Many battery powered & will work for quite a while during power outages. Something like Ebay #320574010639 with bad traction motor etc. An engineered product like this has less catastrophic failure modes than a jury rigged lift. MikeD74T

Now that's thinking outside of the Box Mike! Great idea:thumbsup:

spurlocktool,

Nice work on the lift. I would like to build something similar to lift Zero turn mowers up to working height. The base would have to be wider than shown. Do you have any basic plans, and detail descriptions?

Thanks JJ,

I'm heading over to take detailed photos this afternoon, and will write up a post this weekend.

Spurlocktool, Does your lift have any brakes? The reason I ask is that I was a juror on a case where a person was injured on a similar but larger scale lift. A few years later I worked briefly for Giant Lift Company welding lifts. On their chain operated lifts were hardened serrated cams that were held open by chain tension that would grip the giuide rails if the chain failed or even just accumulated slack. In the civil suit above the car was suspended from an electric chainfall, the car got stuck in the floor opening then suddenly fell free with about 5' of slack in the chair. The occupant was half out of the doorway at the time. The top of the car broke his back & would have cut him in half if there'd been more slack. Car had no brakes.
I do admire the quality & ingenuity of your work. MikeD74T
