We can special order 40" or 50" linear actuators which can move 200 pounds. One configuration looks similar to a hydraulic system, the other uses a traveller on a rail. If either of these are of interest, please contact us via the RobotShop Support Center and request a quote for whichever you want. We would need your tel#, full name and address to create an account.
For the 40" versions:
RB-Fra-00 “FA-200-IP66-12-40” (40" tubular actuator)
RB-Fra-00 “FA-200-TR-24-40” (40" track actuator w/ wired hand controller)
The limit switches are not adjustable out of the box. You might consider one on either side or just one towards the center. In either case, the counterweight will be needed.
