ABSTRACT:
A sideloader elevator platform that is particularly structured to serve a cargo opening in the sidewall of, e.g., a truck body. The apparatus includes a platform connected with a novel carriage assembly that is slidable along rails mounted beneath the truck body's bed and transverse to that bed's longitudinal axis. The novel carriage assembly includes hydraulic rams that cooperate with parallelogram linkages for raising and lowering the elevator platform. A novel roller chain drive system functions to move the carriage assembly and platform on the rails between a travel or storage position entirely beneath the truck body's bed and an elevator use position where the platform is extended outward beyond the truck body's sidewall. A novel latch system insures the carriage assembly and platform is retained in the extended position when it is desired to use the platform as an elevator, and insures the carriage assembly and platform is retained wholly beneath the truck body's bed and above the axle centerline of the truck's wheels when in the travel position.
