Hie;
At our site we have a 10ton overhead crane. Twenty years ago, it had emergency braking system that was only operation in the case of an electrical power failure. We did not establish why was this system disabled. Now we want to resuscitate it but have no specs. Does anyone out there have an idea of where I can get one.

Jingas,

I would recommend going back to the manufacturer to begin with as they know the parameters for the emergency brake circuit.
