Hello, I am currently designing a lightweight waterproof winch system using off the shelf electrical or hand winches. My problem is that most electric winches that are waterproof are too heavy (design weight limit ~10lbs) and have a much higher force rating than needed (design max force ~500 lbs). A hand winch could be used, but the process needs to be automated and it will probably take too long to couple it with an appropriate sized motor an enclose it in a sort of pressure housing. Does anybody have an idea where I can find small scale IP rated winches? Or have any easy way to automate a hand winch? Thanks!
