DOCK LEVELER FOR LOADING DOCK WITH INTEGRAL ON-DEMAND COMPRESSOR AND PNEUMATIC ACTUATOR

摘要

A loading dock leveler with: a base; and a deck with a top platform, the deck having an inward end hingedly mounted to the inward end of the base for movement between an upper position and a lower position; an air compressor having a compressor capacity defined as a predetermined volume of compressed air delivered at a predetermined pressure delivered during a predetermined time period; a pneumatic deck lift actuator, comprising a pneumatic cylinder pivotally connected to the base and to the deck for rotary movement wherein the direct communication between the lift actuator inlet port and the compressor outlet, without a compressed air storage receiver tank, delivers compressed air directly from the compressor to the lift chamber at the compressor capacity within a lift actuation time period, and wherein the lift chamber volume divided by the compressor capacity equals the lift actuation time period.
