How to Wire TWO separate wired Controllers to One Electric Hoist

[Tudunka]

Hi Fellas,

This is my First Post here in this section - So Howdy to all. I have been trolling for a while and like what I read.

I am building an electric elevator using a HF 2000lb 110v, 20a electric hoist that has one cabled remote. I looked at a wireless solution but its very complicated because of the 20a requirement.

Is it possible to connect TWO cable remotes to a single hoist? Can I just purchase a secondary similar cable remote and just connect the wires like the original one that is connected to the hoist now?

Any input is greatly appreciated!

Thank You.

Andy

There was this thread posted some time ago that do it with a micro controller here, more specifically arduino and two SSR... then you can just use any input you wanted... If you are that adventurous to try. I think you can find that project in .....one of those sites...

Mechanically you'll probably have to inventively use relays.. me not that good maybe some one will tell you...

It's just one of those project that have cross my mine as well.. multiple remote to one winch/hoist.

This is the link to that post here...

Hi DogDog,

Thanks for your post. Yeah, a little more than I want to get into, so thats why I figured the simplest way was to just connect another cabled remote.

Any and all ideas are welcomed !

Thanks,

Andy

It all depends on how the hoist is wired. Some of the HF hoist have the capacitor mounted on the motor and some have it in the hand controller. I wired in a second hand remote on my HF hoist but the capacitor is on the motor which made it easy to do.

You can do what pattenp did, he have a great thread and pics (or maybe just great pic on that), but keep in mind (or be aware) when wiring two switch without some sort of isolation. (It's basically Double Pole Double Throw and Center Off switch)... you'll have to make sure no body else press anything on the other end or the other end is at the OFF position.. or Karboom Baby... well maybe just a fire or shock... that is why if you don't use any sort of safety scheme, that is the risk. If you are a one man shop it might be ok.
Not sure what industrial setting does to solve for these cases... pretty sure I have seen them.

Hi Pattenp,

Thanks for your input. I opened up the motor wiring box and there are TWO beige looking cylinder like items in there that look like oversized D batteries. Is that what you are meaning about capacitors?

What do I need to look for in the cable remote?

Can I simply order another similar remote and just wire into the same wire places as the original remote?

Thank You !!!

Yes. I made my remote by using SO cord and a momentary on-off-on switch and used a LB conduit body for the hand control box. My original remote hand box only contains a switch so there was no complicated wiring to do.

Pattenp,

Perfect, just what i'm trying to do. So, if the unit is 110v, requires dedicated 20a circuit.... i've seen some posts where you have to have a 20a switch (remote) so,....

Did you have to do find a toggle switch that handled 20a or did you just use a 10a toggle switch?

Thank You VERY MUCH for sharing your information.

My hoist only requires a 15A circuit so finding a switch wasn't a problem. The switch I got was 15A at 120V also had a 3/4HP motor rating which I believe would work just fine for you. Don't ask where I got it because I don't remember.

Pattenp,

So it looks like you created a junction box with 8 post block (2x 4pair blocks) to simplify the wiring - is that correct?

Thanks,

Andy
