One extremely important part of any powered winch
(or windless) is the solenoid (relay). I am concerned whenever I use a solenoid controlled winch
due to a previous bad experience. My solenoid's contacts stuck closed and the solenoid control switch could not stop the winch motor. It was a mad scramble to get to the winch circuit breaker to stop the errant winch and prevent serious damage to life and property.
This only happened to me once, because after that harrowing experience (trying to get to the circuit breaker while the winch is still running) I installed a kill switch that would disable all power to the winch and was easily accessible by the user.
When you add solenoids to any winch project
, ensure the contacts can handle the load current
without sticking. Even properly sized solenoids, can become pitted from use which results in unexpected sticking.
I cringe each time I see someone lowering a mast
to step it with a solenoid controlled winch. This would be a very nasty time for a solenoid to stick! You may want to consider placing a safety
watch person at the circuit breaker for that winch. Ignorance is bliss until it becomes an accident
