US Patent:
3943714, Mar 16, 1976
Filed:
Jan 23, 1975
Appl. No.:
5/543612
Inventors:

Abstract:
A valving arrangement for a winch motor powered by air or other pneumatic uid. The valving arrangement includes normally closed valves in the working fluid lines which are held open by air in the pilot fluid lines. In the event of a rupture or break in the pilot line, a normally closed valve is allowed to close, thereby stopping the winch and preventing it from overrunning its travel limits.
