How to change a Pulling Winch to a Pulling and Holding Winch?
(OP)
I am planning to adapt to my electrical winch a hydraulic motor. My electrical winch is only for pulling (Not Include Brake) I thing that adapting a Hydraulic Piston Motor it could work not only for pulling but also for holding if I include a contra balance or holding valve, therefore I believe that wouldn't have to use a hydraulic brake to hold the load. Is this proposes right?
I understand that gear motors doesn't work to hold without mechanical gearing or brake because motors have internal clearances which will allow rotation to occur even when the holding valve not leak. Is it the same in Piston Motors?

It depends on how critical the application is. Load to hold and for how long. Just for example, if the load drifts a foot in 30 minutes is that a problem? Must the load not move at all for any length of time?

Would you sleep under it?

Ow, I just pulled a muscle in my brain.
Seriously, when I read "winch" I thought of something pulling horizontally, not hoisting. Still a valid point, but more generally - will loss of holding cause risk to human life and/or safety?

Depending on how big is your application you have to choose for a clutch unit able to sustain the load.
Remember that you are not going to be ale to go in both ways – you are going to have only two functions: hoist and hold.

Also many of the electric brake companies make brakes that will bolt in between the motor and motor mount.
