Sailplane Winch Solenoid Safety Buzzer
Miami Mike writes:Recently our club’s winch went out of control and destroyed a glider. The operator took his foot off the pedal but the motor kept running, folding the glider’s wings and slamming it into the ground. Fortunately the winch had a cutoff switch and we were finally able to stop it. It happened because our winch only had one solenoid and the contacts inside had gotten stuck together. We now have two new solenoids wired in series, and I’ve designed a small device to help prevent this sort of thing from happening again.
