Thanks everyone for your suggestions. This is the first bit of success our team has had in years. A lifting robot may not mean much to a lot of you but to us its awesome.
Congratulations on the progress.

This would be an ideal opportunity to learn about adding something to stop the carriage before it hits the top or bottom, and possibly damaging itself. The most obvious would be to use a limit switch at the top and one at the bottom. Other options include distance measuring devices such as an ultrasonic sensor or a Lidar (that is what we used). Each has it's advantages and disadvantages and this is a good time for your team to learn about them.

Once you add the manipulators (arms, claws, hooks, etc.) for picking up the totes, you may find that you will want to relocate your motor so that the spool and strap are centered on the carriage. Otherwise, the carriage may twist as it is lifted, spread the two vertical tubes and become de-railed.

Keep up the good work.
