Garfield-Palouse High School
Agricultural lift for people with disabilities
We will invent the Paraplegic Agricultural Lift (PAL), a remote-controlled lift that will provide three axes of motion and be capable of raising a person from ground level to the cab of a combine or other hand-operated equipment. PAL will be able to lift 600 pounds, de-rated at 300 pounds. The electrical system will consist of a remote-control system and a solid-state switching circuit utilizing an N-channel FET, H-bridge with feedback control loops, and include limit switches.
