We will use winch motors that can backdrive (Fischer Price) and will need a device to prevent backdriving as well. Has anybody come up with an elegantly simple way to accomplish this? We would like it to be a passive device, similar to the clutch in a manual window regulator mechanism.
We'd rather not have to use a cylinder/blocker device because of the weight. Has anybody had experience using an electrically actuated servo to move a latch pawl or something like that?[/quote]

If you take a look at this device it is very simple to stop a motor to back drive. we use this claw to hold onto the 180lb goals and pull them around. Vey strong.
