Re: What motors are you using for your lift?
We have set up two opposing VexPro 2 speed ball shifting transmissions.
One has 2 CIM’s the other is only used as a shift on the fly ratcheting system.
It lined up so nicely putting the transmissions together..
Gear ratios of 8.33:1 and 3.6:1 on a custom 3d printed 1” diameter spool and strap guide system.
Per the JVN calculator, our low gear should move our 60” lift system fully in approximately 2 seconds with a 40lb. load and a stall load of 570lbs at 10amps. The high speed, which I doubt we will use much, runs the loaded lift at less than a second with a stall load of 250lbs at 19 amps.
It is “overkill” and so is the lift system that goes with it..
We will be adjusting speeds this week to fine tune the lift. Sure do not need to launch those totes into the stands..
Good luck to everyone this year!
Aloha!
