need a 110V winch
Frank, a 'safety mechanism' doesn't have to be rocket science.
Although I wouldn't want to stake my licence on it, as an Engineer I can tell you, a couple of stout hardwood beams with ratchet dogs carved into them, and a pair of ratcheting bars that engage the dogs on the beam would be more than enough to do the trick and only let the car drop as far as the last dog the ratcheting bar slid over, maybe a couple of inches at most.
My suggestion would be two horizontally opposed hardwood planks under the car, sliding back and forth in a track in the center of the car with a spring between them pushing them outwards and into the notched beams.
Of course I still stand by my original suggestion too. For about the same cost as fabricating an elevator you buy a used forklift that would be useful for far more than just getting stuff up and down off the mezzanine.
Best of luck.

EW, the person my commnet was meant for understood it. all that mattered.  Could be he has more brain ability than some.
Frank, on topic of elevators in hotels, did you hear about the old guy who took his family to town. His wife and daughter went off looking at dresses: he and he son stood watching the elevators. An older weathered lady got on one and the lights flashed and the bells rung (EW they really did do this) and the doors reopen to find a much younger, fairer skin lady stepped off. To which he said to his son, quick, get your Maw! BTW EW, did it work?
Frank, a few years ago there were companys who made small elevators that could be either used inside or out side for Churches. The best I can remember the price was low and the capacity may be too low for your use, but that may be an option for you. They were designed to suit wheel chair use.
Murf, I truly agree with insurance agents not being clear. Many have no idea what they are selling. Then some don't want you to know what they are selling. Then some times you can get a straight answer from a company holding a gun to their head as you probably already knew. It can be amazing where you find the important part of a contract. kt

Frank,
When I worked in the foundry, pouring molten metal, we used chain hoists to lift the ladles. Dropping 3000 pounds of 2800 degree molten metal is something that you don't want to happen.
The chain hoists have e-brakes built right into them. Should something in the hoist fail, the chain won't drop.
I know a chain hoist would cost a bit more than a simple cable hoist --- but the hastle of designing and building an emergency stop brake is eliminated.
Chains do wear out over time, but on an elevator such as yours, I'm guessing that a chain would last at least 100 years.
Murf,
When I finish my new building, I plan on having an overhead loft much like Frank's........and I'll be installing an elevator as well. Forklifts are great, so long as there is room enough to move one around. But if I had enough room to move a forklift around, I wouldn't need a loft.

Joel, I understand what you're saying about space, but think you're missing a few salient facts.
In the original post Frank said "I'm in need of a 110V winch that will lift 5-6000 lbs. in a reasonable amount of time.".
My first thought is that unless Frank's in better shape than me he's going to need a forklift or something similar to it just to load the lift itself. I doubt too many here are up to humping 5-6k pounds around by hand anymore.
Secondly, I doubt a forklift would be any larger in footprint size than an elevator would be.
Finally, a forklift can be stored elsewhere and not take up 'prime' storage space, an elevator is sort of tough to move around.
Best of luck.

Murf,
I agree. Loading the elevator can be a job. Unloading the elevator would be even more difficult, as there would be no way of using a forklift in the loft.
I plan on pouring my floor with a depressed area for the elevator, so that the floor of the elevator will be level with the shop floor, making it possible to roll a pallet jack right in. Keeping that depressed area clean and dry will be the only challenge, as it won't be possible to simply sweep it out.
A pallet jack can be lifted into the loft, right along with the load, making it necessary to keep just one pallet jack on hand. Pallets are the only way to go with this system, as there's never any lifting involved.

We do something similar, but the pallet jack permanently resides on the mezzanine and there is a shelving unit that stands against the wall where the lifting is done. When something has to go up or down that is too heavy to be moved by hand, the shelf unit is carried out of the way with the forklift, and the stuff moved up or down, then the shelving put back.
We can't afford to waste that much space by having a permanent elevating device taking up room that can't be used for anything but moving heavy stuff up & down on rare occasions. The commonly used stuff is all on grade, the only stuff upstairs are long term storage, light stuff, and the bulk tanks for oil, & etc.
Besides, in Ontario, as in most every other jurisdiction in North America, a permanently installed elevating device has to by approved by the Government as well as UL or a comparable safety authority. Lot's of hoopla for naught.
Best of luck.

Murf,
You are correct about the regulations and other red tape involved, but such regulations only apply to employers. Private individuals are not regulated in such ways....at least not here.
Even so, I would hard-wire the hoist, and then install an electrical lock-out switch panel on the wall, with padlocks on both the panel and the switch. This would prevent any children from playing on it, except at ground level.
It is true that the elevator would take up some valuable space on the shop floor, but the trade-off is well worth it. The additional 1500 square feet of floor space above, is well worth the lost 48 square feet (6'x8') of floor space the elevator cage will consume.

Joel, I think you will find that ANY lifting device is required to be certified as safe by UL or others.
The licensing of passenger elevators is a whole other matter.
In my case the few square feet of floor space was worth far more than the $1,500 I paid for the forklift, the additional uses are just a huge bonus over & above getting stuff to & from the mezzanine level.
Best of luck.

The government may not require inspection if in private use but any insurance company that insures such a building would have hard time with such if not UL approved and installed by license contractor. That I have very little doubt of. Then if that was not done and by chance some one got hurt due to it they probably would not be liable even if they were not aware such was there as more than likely they have a line in the contract such must meet such standards. kt
During lunch stopped by my house and was going to look at hoist in the New Northern Tool Catalog due to this thread, did not find any electric hoist in there. Did I miss them or is there a legal issue pulling them or did they just not sell for Northern?

need a 110V winch
When I was rebuilding Katrina-land I partnered-up with a huge Florida-based vertical conveyor manufacturer (notice I did not say "elevator" . The Gulf Coast has some homes that may have to built up as high 38 feet, so some means of transport was necessary.
We found that:
Private "personal lifting devices" i.e elevators have to be inspected by certified elevator inspectors once a year.
"Material and cargo vertical conveyors" do not need inspections. They do not any safety devices whatsoever. Ours had double cables.
We were selling "cargo lifts" for residential use which were not governed by laws necessarily. The buyer was told they "are not allowed (wink, wink) to permit anyone to ride the lift---and sign here that you will not use it for that."
Millions of products are used everyday that do not carry UL listings.
