The invention discloses a switching-type automatic loading and unloading freight lift, and relates to the field of automatic lifts. By adopting the switching-type automatic loading and unloading freight lift, the problem of automatic goods loading and unloading of the freight lift is solved. The switching-type automatic loading and unloading freight lift comprises a chain pulling device, an inner chain, an outer chain, bearing plates and supporting rods; the chain pulling device is connected with a motor through a conductor; lift leading chains are adopted as the inner chain and the outer chain; the inner chain and the outer chain are arranged in the chain pulling device; the inner chain is provided with supporting rod fixing holes; the outer chain is provided with bearing plate fixing holes; one end of each bearing plate is hinged to the corresponding bearing plate fixing holes in the outer chain, and the other end of each bearing plate is hinged to the upper ends of the corresponding supporting rods; and the lower end of each supporting rod is hinged to the corresponding supporting rod fixing hole in the inner chain. The inclination angle of the bearing plates of the freight lift is controlled for goods loading and unloading; the efficiency is high; and the structure is simple.
