Pushing a loaded cart across a plant or down a hospital corridor a few dozen times a day wears people out and slows deliveries. A battery-powered cart puts a motor under the load and a throttle at the handle, so one person moves weight they could not push on their own. When the loads get heavier still, towable trailers ride behind a tow vehicle and couple into a train.
This collection covers traction-drive carts for indoor delivery, electric material handling carts rated from 500 to 2,000 lb depending on configuration, off-road powered carts on pneumatic tires, and towable trailers in caster steer, fifth wheel steer, and all wheel steer designs with capacities up to 10,000 lb.
