Hey all....from a glance, does anyone know if this 2 ton hoist is wired for 3 phase? I think it is, but I'm not sure. It has 4 wires coming into it, 2 red, one black, one green. The green is grounded to the frame. the 2 reds and black connect in the middle between those 2 transformers. I believe this is wired 3 phase delta, but I'm no expert. I tried the 3 connections to 240 single phase, and i got the contact transformer thing on the right to click up and down when using the hanging control switch. A different configuration just gave me a hummm. I want to try and test this hoist, using capacitors, without shelling out money for a vfd or rotatory converter. Let me know please.

Have a photo of the data plate? If 3 phase a VFD will not work either a rotary phase converter, or static one, or better yet, get 3 phase, :D but that one would be too costly.

Contactor looks like three phase to me. I found a like model number on eBay that lists it as three phase as well.

For sure that is a definite purpose 3 phase reversing contactor. Small transformer is for the control pedant and possibly the brake. There is a brake as part of the hoist or motor. Brake does not disengage unless the contactor is energized one direction or the other. Really going to need three phase for this.

BTW, the only transformer is the part with 209717-1 printed on it. The other two "transformer looking" components are the contactor coils.

Phase converter is not a great idea. It will lift the bare chain no problem but will struggle or fail to lift on a rated load. If used, the control transformer must be wired to the "power company" legs and not to the generated leg.

A RPC would be fine but a static converter would result in 1/3 loss of HP. The NEC prohibits control wiring being on the generated leg.

Having once bought a Budget hoist that was 3 phase, thinking it was 115 volt because some ******** put a 115 volt plug on it, I now know the easy way to tell is to look for the start cap. Luckily for me it was only $25., figure worth that in parts for one of my single phase ones if I ever need some. Or if anyone is looking for a 440 volt 3 ph hoist for cheap, PM me, tested it, it does work on 3 ph.

Maybe, but I would want a RPC with at least three times the rated HP for the reversing and heavy starting loads of a hoist. If you are trying to use this hoist on the cheap because you got it for a good price, you might want to reconsider it's "bargain" value.

Two tons is a lot of hoist, do you need that much? Is the rest of the structure up to those loads? If the answer to those questions is yes, then spend the money to make it work correctly.

As a person who has wired and run a 3phase hoist on a rotary converter in my own shop, my advice is that its undesirable. Inching a hoist under load involves a lot of inrush due to starting under load, and that's not where a rotary converter shines. I was unaware the NEC had any jurisdiction over rotary phase converters other than standard wire/breaker/amperage sizing and "protection" specifications for variable and fixed loads.

There are 120vac 1ph hoists out there but they are $$$$.

I got it super cheap, $20. I don't even need the lift, I'm not lifting anything close to 2 ton, and my shop floor joists will not carry anything close to 2 ton. My main goal was to see if I can get this thing working to sell, or just to get my feet wet with 3 phase, and to have another toy laying around ha.

I messed with it last night, and got it working. I disconnected the 3 wires running to the motor, and wired 2 hot and the 3rd leg on a 10uF cap, it tried but didn't budge. The only other cap I had was 1000uF so i wired that up and she came to life. Electromagnetic relay is busted, the plastic frame is cracked on the "raise" side, so that contact wont engage, so at the moment it will only lower the hook ha, not very useful. I will look into trying to fix the relay or see if i can get one for cheap (454ragtop maybe?)

So after verifying the motor itself worked, I wired it back into the relay, had the 2 real legs running to the 220 transformer, and tried it out with the hanging switch, once again only "down" worked. Opened the control switch up and the one wire came loose, but even after reconnecting that and checking in the hoist, the up side wouldn't work, leading me to believe the relay is shot.
