Abstract:
This lift system serves as a powered ladder having a small footprint. The system is divided into two subchasses with a mast fixedly attached to a first subchassis for support of a liftable platform which may carry a human operator. Maneuverability is accomplished by a virtual articulating joint between the two subchasses. The joint comprises hydraulic cylinders operating in conjunction with wheel struts to form a three-point support. Articulation enables the lift system to be adjusted on sloped or uneven terrain to maintain the mast in a vertical orientation. One use of the lift system is to carry a fruit picker into an orchard or vineyard and to position the picker to work efficiently. The lift system may carry a robot and may be controlled either locally or remotely.
