Motors, Electrical & Controls
The motor is the part owners think about most and understand least. Lift speed, battery life, breaker trips and remote range all come back to a few numbers: voltage, current, gear ratio and wire size. These guides explain them with worked examples.
Electricity and water: stray current in the water around a dock can cause electric shock drowning. Dock and lift circuits should be installed by a licensed electrician with the ground-fault protection your local code requires.
