Forward and Reverse Linear Motion over a 24 foot span
Forward and Reverse Linear Motion over a 24 foot span
(OP)
First post here (just as an FYI) and, yes, I did try the search function before posting. Did find some similar postings but not exactly what I was looking for.
Any suggestions for a small drive motor that can move in forward and reverse directions with the flip of a switch?
I have a device that will be suspended from an overhead rail system. There will be two rails 10' (centered) apart from each other - like an overhead crane system. The device will weigh about 1000 lbs (max) and will experience about 1000 lbs of resistance force in each direction - picture a bulldozer moving light weight dirt.
The system will start at one end of a 24' long rail and move to the other end. Then it will rest until the operator sends it back to the original start position.
I will need two motors - each motor should be able to move 500 lbs of dead weight (weight of the device) and be able to overcome the resistance force of 500 lbs linearly.
I am not very familiar with electric motors, so I am asking for help and/or suggestions for this one. I am NOT opposed to other drive line (hydraulic, pneumatic, etc)suggestions either. I have the rest of the system designed out - just need to figure out the drive system so I can finalize the design.
I have a max budget (design and build) of $10,000 but would prefer being way under if possible.
Any/All help is appreciated.

Dave's question is 1a on the list of most important questions.
How much accuracy is required?
The above question is 1b.
19 more to go.

Unless you are lifting the weight that should have little effect except as to how acceleration is limited by the mass.
I'd select a 1 HP setup to cover for unforeseen changes. System stiffness is also a consideration to avoid stick-slip/shuddering. Coordinating the two supports will either take a mechanical connection or use two motors and use a servo system.

Now - why can't i reply directly to threads or quote anyone? Is that a time-here thing?
