I posted the following in the schematics section but I also wanted to post it here if that's allowed

Hi
We have been contacted to remove an old platform lift in a stage. It is a Cemco unit with an in ground jack and an ESI controller. It is equipped with electromagnetic brakes that keep the platform from drifting while not in use. Does anyone have the schematics for this type of brake or is there a manual way to lift the brake.
Thanks in advance for any help
Chris
