need a 110V winch
I'm in need of a 110V winch that will lift 5-6000 lbs. in a reasonable amount of time. I'm building a freight elevator for my shop and had thought of using a 12V winch but they show only like 5-7 ft. of lift per minute for one in the "Reasonable cost" line, (2-300 dollars), that seems pretty slow. The ones I would like in the 110V, with faster lift times, remote and all that are in the 12-1600.00 dollar class. Is there a less expensive way to do this? I really don't want anything to do with E-bay or any of the online auction stuff, I still like to go to a store, junk yard, where ever and look at something, then buy if it looks good. Frank.

Hrvey; In the real world I would never lift anything half that heavy, but just wanted the added in safety factor of not stressing things to the limit. Or do winches already have a built in safety margin? Frank.

need a 110V winch
Thanks for all the info. I'm going with a 3000 lb. rated cable wrap enclosed worm gear drive hoist W/3 hp. belt drive electric motor. Ok, get your calculators out. Final ratio is 215/1 between the cable drum and the 3450 RPM motor. This gives aprox. 16 RPM of a 4 1/4 in diam. drum driven by the 3 hp motor at 3450 RPM. This should work out to 13.5 inches per wrap on the 4.25 in drum at 16 RPM equaling aprox 18 ft. per minute of lift. I need 10 ft. of lift, my calculations work out to 34 seconds to lift the 10 ft. with this setup. Did I do any of this right? Please coprrect my calculations if I'm wron, I'd rather know now than after the thing is hung in the building. Thanks, Frank.

EW; Yup, the helmet is on. And Yup, did the first/second/third wrap research. I only need nine wraps on the drum for twn ft. of lift. The drum is plenty wide for nine wraps of 3/8th's cable. Frank.

Yes, I've always felt a lot of comfort here, most of you even agree with some of my most goofy ideas. Murf, I had been thinking about some sort of a safety brake or catch thst may allow my insurace agent to get off the double dose of Prozac. Surely there has to be an engineer or a math wiz or two here to check my calculations and maybe even my sanity. Frank.

KT; It's just like Allstate around here, again I'm in "Good Hands".
Joel; Thanks for the links on Otis, I'm sure it was him that they featured on the History Channel a while back about his elevators. My shed has enough overhead clearance for a loft floor at about 10 ft. above the concreet to provide 1400 sq. ft. of storage with enough head room for a 6 ft. tall person to walk around without having to duck.
EW; Would you recommend a helment for may head and butt both?
Probably 20 yrs. ago the local grain elevator took a busload of farmers in to the Chacago board of trade for a day. While touring the building I was fascinated by a bank of elevators that started at about the tenth or so floor and went up to however high the building is. The elevator cars were not enclosed by the typical elevator shaft, they seemed to be just along a wall and you could watch all of the mechanical parts work. I remember that at the very bottom of the shaft's there were several huge coil springs probably four ft. tall, I suppose they were to be a last resort in case of a catostropic free fall. I wonderd how far the car would bounce back up if that happened. Likely some adult diapers would be in order too. Frank.

Murf; I like your idea on the opposed spring loaded planks, I had a somewhat similar idea in mind but I think you improved a bit on my design.
KT; Probably 15 yrs. ago I got volunteered to be the head of a crew at our church made up of very capable volunteers from our parish to design, build and contract for an elevator to be installed in our new handicap entrance. It was interesting to do this simply for the learning experience about public passenger elevators. We had to by the rules of the Arch Diosesis (somebody correctly spell it for me, please) get three bids on the elevator. We turned down the two lowest, not by much in favor of a local person who had a good reputation for church and school elevators in our aeria. Yes there are many interlocks and safety devices to check on door closings, overload sensors, on and on, but all for good reason. It has worked almost flawlessly to this day. Little did I realize at that time that today in 2007 I would be one of the primary users of this elevator. A local welder has access to used forklifts of most any quality. I've looked at his typical "Inventory", most have more oil on and under them than is still left in them. They are cheap, yes, but a woodshop and a leaky old forklift just don't mix too well. I also looked into a new systwm incorporating a hydraulic lift, but I just don't want any oil within leaking or spurting distance of some hardwood lumber that is now, Cherry for example pushing six bucks a board foot. Thanks again for all the help, I think i've pretty much decided on the basic design and will stick with the cable wrap hoist I described earlier. Frank.
