Yes, its can be a dangerous machine, the handle can easily be unbolted for safety and a housing cover can be made if you are industrious. I operate it from the opposite side.
The motors and belts come from a wholesale supplier but they are standard electric continuous duty motors with cradle mounts. this model is 1/3HP. We can supply you with belts, motors and pulleys if you have a GPF 1 juicer and want to motorize it. The pulleys we use take A style belts. length is dependent on mounting distance.
We are manufacturing new carts/stands that will have caster and mounts for our juicers. they will include a spot to mount an electric motor. Or you can keep it manual crank. It takes about 3 seconds to revert back to manual crank by removing the rubber belt.
The benefit is having the two options to manually crank in off grid applications or if power is out, or motorize it and get to making some serious juice.
