Is Anyone Using Motors to Hoist themselves off the platform on the bar?

[bigqueue]

We do the actual lifting with a Van Door motor....but we position our hook with the lift motor.

I think our system is pretty straight forward.....but I have a question. Does the VAN door motor have a thermal overload protection PTC in it? Does anyone have the specs on it, and how it cuts out. (vs load?)

Thanks,

hey,

how powerful is the Denso-Window motor, and which motor do you guys think of the most strong one. Can a single Window Motor lift the whole robot up(130 lbs), if no than which one can. I know this is a lat to be asking this.

We had a mechasim that uses a single window motor to move an pivoted arm, with a light grabber, but when we hold on the ball the thing wont go up. But it works pretty good when not holding on ball. Also the arm is about 56 inch, but if we put the ball at about 30 inch it work okay. THe arm is mounted on a 60 teeth sprocket(drilled through and bolted) the window motor has a 20 sprocket so basically a 3:1 ratio. Any comments to help us on this, fast replies will be appreciated.

The window motors seem to have a lot of play. We used them for our arm last year to grab tubs. I see a lot of people using the van door or globe motors.. I think these are better choices. We are using the van door motors.

We only get one and two would be a waste of weight anyways.

Yes, some calculations from the end of the pole to the bar revealed that our pole moves at around 8 feet per second. However, since it is located rather high (approaching 5 feet), it takes pretty much a second to hit the bar with correct positioning on the floor.

here are some videos of the pole in action
