What would be the best design for a chain elevator system for an arm? I don’t know very much about chain systems, but I have seen it used often in the FIRST Tech Challenge. Also what is the average height that a chain driven raising system can raise to. :confused: Thx in Advance, Doombot

personally i find that the height is unrestricted, but the the number of stages that could actually function using linear slides is limited. i use a setup similar to: http://www.vexlabs.com/conlift.shtml and: http://www.chiefdelphi.com/forums/showthread.php?t=41125&highlight=chain+lift+picture h…

Thanks for the idea. Would you suggest using one chain kit or two?

i only have one right now, but i do need another, and also you may want to buy the vexlabs linear sliders to make the motion easier to create. i have 2 sets of these to allow for 2 stages

I built one last year and it was a pain but when it wirked it worked great and when it sucked it sucked bad. I would suggest that if your moving a up a foot then buy 2 and 1/2 feet of chain or about 2.5 times your travel distance.

if you are going to use chain to lift this arm, I highly unrecommend it. Chain is used in bicycles and in motorcycles, but it is never used in high power machines like cars and trucks. As said in the Inventors guide insert, Chain transfers 95% of the energy from the driving axle to the driven axle,…

Important Considerations when Building a Chain Lift: [LIST] *]The Vex chain is made of plastic, and has a limited tensile strength. (If you pull on it too hard, it will snap.) *]Using 2-chains in parallel means that each chain shares 1/2 the load. Using 3-chains in parallel means that each chai…
