ROLETES da carretinha com acionamento ELÉTRICO

I made a 12v electric jack with a windshield wiper motor to operate the trailer's rollers. This system makes loading and unloading the boat onto the trailer much easier and is very helpful for people who can't exert force for some reason, especially elderly fishermen. After removing the tie-down straps, I only need to press two buttons to lower or raise the boat on the trailer. I appreciate your subscription to the channel and thank you very much for watching this video. Denis Medeiros
