Wireless Controller for 120-V Hoist

A garage door remote should be adaptable for this.

This has about a 50' range...

You'll need to wire a control system that controls the winch, this is for 12v system so you'll need a few relays....

Thanks. We were trying to avoid using relays, but we might not have a choice if we don't find anything specifically for 120V.

you can add a relay if the 16/3 is insufficient

Two of these, one for up one for down, should wire directly into the hoist control circuit. Keep track of which remote is up or down...

Go to www.Digikey.com and type in Remote Control. Then select "RF Receiver, Transmitter, and Transceiver Finished Units"

Just need to make sure you don't key in Up & Down at the same time, Group All on, or key in the 8 second sleep delay

That 120V hoist is rated at what full load current? Could you use a power inverter, and control that with on/off relay that is wireless?

I bet it can be done, but you have more research to do, obviously.

What or who are you lifting? Please make sure that all of the color guard team are clear of pinch points and crush zones when this is in use.

I'd also suggest that you keep the wired remote in place in case the wireless unit fails.

We are lifting several team members. All are teenage girls, 120 pounds or less. We have taken great care to eliminate pinch points and any possibility that fingers, hair, clothing, or anything else could come in contact with the hoist or pulleys we are using. Safety is priority one! If it isn't safe, it's not being approved by the dads for use. We also test everything on ourselves.

This prop will be used as part of the performance, and the remote has to be wireless. If it fails, we're in trouble. We will probably keep the wired remote for safety reasons, but it cannot be used during the performance.

We are using a hoist we purchased from Harbor Freight.

The wireless remote must have two buttons - one for up and one for down. We need them to be momentary, so that the hoist moves when the buttons are pressed and stops when they are released.

I found the this controller, which we are looking into a little further.

You do need a plan for unexpected movement, as it is possible that once starting up or down, the signal to stop movement may not work, for many reasons, even within the hoist controls, not including the wireless component of the control.

Are they going to be suspended, as in flying? ..or supported as in standing on platform?

A counter balanced pulley system might eliminate the need for motors...

...as used in rock climbing...

Suspended, as in flying. The counterbalance won't work because they need to raise and lower themselves and also switch from one performer to another. This is the winterguard version of colorguard - nothing is ever easy.

Maybe some professional help is called for....?

If only we had a budget for this, or were on a stage (we're on a gym floor). We also only have 45 seconds to get our prop through a standard 36" wide door, in place on the floor and fully setup and 45 seconds to tear down and get out a 36" wide door at the end of the performance. He team is assessed penalty points for every second the setup, performance and tear down exceed the time limit of 10 minutes. The performance itself is about 8 1/2 minutes.

The last thing I expected to use my engineering skills degree for was my daughters' extracurricular high school sport. Here is what we built the past couple of years. They didn't use electricity, but some of them were on casters and got moved around during the performance.

It is pretty elaborate, but nothing is too much for your girl, right?

I wish you all the best of luck.

In case a push button sticks closed, or the control contains a stop button, there should be a way to interrupt power to the whole hoist, which could be monitored by an offstage person.

I hear you, and I understand. There are strict rules on involvement of anybody not part of the competitive team. This is a competitive team sport, and we are not allowed to be actively monitoring or helping out in any way during the performance. The performers will never be higher than about 9' in the air. Still high enough to cause injury, I know. Believe me, if it were up to me, we'd deep six this hoist and prop all-together. Unfortunately, it is not my decision. We won't let them use it, if we aren't certain it's safe. I'm actually just as concerned that a parent is going to get hurt moving it around and setting it up. Each prop probably weighs 500 pounds and is 12' tall, and we have THREE of them.

Sounds like a law suit just waiting for a place to happen...but there again I am feeling pessimistic right now.

I couldn't agree with you more. I am not feeling it this season, which is unfortunate because it's my daughter's senior year, and last year on the team. They did win World Championships last year, so at least we have that memory if this year doesn't turn out well. Keeping my fingers crossed that everybody makes it through the year safely.

please tell me there are substantial outriggers of some sort being deployed and that movement of the performers won't compromise any points of the rig?

Try to get through it and enjoy. sound like a workload

Oh yes, we've got VERY substantial outriggers. This thing is industrial! It's made of both galvanized steel and black iron pile (1" nominal size). The outriggers are huge, and the performers are suspended from the center of the rig. There is zero chance of this tipping or buckling. As I mentioned, we test it on ourselves first to make sure it is safe. We all have daughters using it, and none of us wants an injury on our conscious. My bigger concern is actually that one of the parents will get hurt transporting it and setting it up - especially because we are using three of them, and need about 4 fairly strong (and preferably tall) people for each one. I really do have serious concerns that a parent could get hurt.

Hi all. I just want to say thanks to everybody who has expressed safety concerns. I share your concerns and trust me, we are taking every measure possible to make sure that the girls will be safe. Seriously, it is really nice to hear people concerned about the well-being of our kids, and I sincerely appreciate it! Happy New Year everyone!
