This was a test of a friend’s homemade servo winch to see how well it would coupe with a vertical deadweight lift, it did really well and lifted itself all the way up to the hook. Got a bit warm but no burning smells or fires, very impressed.

This was a converted high torque steering servo, with the rope attached directly to the servo motor spindle and using a simple on / off / on switch to control the power to the DC motor for both in and out direction. Hope you enjoy the video.
