Joining Two Devices. Is it possible?

[SharpTeeth]

Hi everyone. New guy here. I am not an engineer but instead an artist who could use some help. I hope I am posting this in the right section.

I am wondering if it is possible to integrate these two devices below? I want to attach a Garage Hoist to a Grow Light Mover. I’m not sure if they are compatible or can do what I want them to do together. Any help would be greatly appreciated.

The end result I want happen is when the Grow Light Mover stops on one end of the rail, the Hoist will then lower an object, keep it there for about 20 seconds then raise it back up before the Grow Light Rail starts to go back in the other direction. I thought the best way to do this was to buy a second Grow Light Mover and detach and use the "timer sensor” to connect to the Garage Hoist.

So in the end the completed finished unit which would ride along the light rail system will have--- a Grow light Mover with sensor in tact and the garage hoist with it’s own Grow light Sensor. when this whole unit moves to one end of the light rail there will be two separate magnetic stoppers. One for the Grow Light and the other for the Hoist.

Thanks in advance…...


DEVICE #1- “GROW LIGHT MOVER”

Amazon.com

Designed to slowly move on a rail system from left to right. When the unit touches a magnet touch point it goes in the opposite direction. There is also a built in timer that can pause the device for up to 120 seconds.

This is a Bluetooth device. There is an app that is used to program this device.

Here is a video of how the app works_

Right, I wasn't certain about the travel length that would be occupied by the Mover. I pictured telescoping tubes (old-fashioned tv rabbit ears), sliding bars... adding flexibility to the motion and time delay as desired.

Youtube has many videos portraying mechanical devices animated.
Hinges, gears, cams, cogs... Might provide ideas. Example:

So here's the update....

In practice the prototype is working nicely. However it can only pulley up to 2 lbs before the motor/mover starts to hesitate and the pulley starts to push in towards the telescope. I'd like to be able to have it lift at least 20 lbs. The motor/mover unit is able to hold 75 lbs from the bottom. I feel like some hurdles have been overcome but not seeing how to get past the weight issue. Two motors instead of one motor and one pulley would probably help create more resistance but probably not enough.

A counterweight might help when the motor bogs down. Attach an equal weight somewhere to counterbalance the mannequin's weight. Then a tiny motor is sufficient to do the job.

It's hard to imagine where the counterweight should go. I doubt you want it in the aisle. Perhaps attached to the ceiling by a pulley system. For a single pulley the counterweight moves the same distance up-and-down as the mannequin travels.

A spring (as for screen doors, garage doors) might be an alternate.

Ideas about using a counterweight:
* Sandbags among stage curtains make it easier for a human to raise & lower heavy curtains or props.
* Railroad crossing gate has heavy weight on the thicker end, so a small motor can raise & lower the gate.
* A lift bridge (or drawbridge) has enormous counterweights at each end, usually hidden from view.

As always great leads Brad. Thank u. But first question is where would the counter weight attach to? The motor?

Attach rope (cable, chain) to bottom of counterweight (labelled M below). Then a tiny motor is sufficient to raise the load (labelled 'elevator'). Diagram from internet:
