Full-hydraulic crawler-type self-moving trestle
A full-hydraulic crawler-type self-moving trestle comprises a main trestle body, a front end trestle approach, a pier, a rear end trestle approach, a hydraulic pump station, a trestle approach hydraulic oil cylinder and a hydraulic control system. The two ends of the main trestle body are each provided with a main lifting hydraulic oil cylinder, and a crawler-type walking device is arranged on the lower portions of the main lifting hydraulic oil cylinders, and a walking steering hydraulic oil cylinder is arranged on one side of the crawler-type walking device; and the other end of the walking steering hydraulic oil cylinder is fixed to the pier. The full-hydraulic control is adopted, automation degree is high, and operation is convenient and reliable; conversion between transverse moving and longitudinal moving is rapidly achieved through a walking steering system; investment of manpower and other auxiliary machines is small; labor intensity of a worker is reduced; the working efficiency is improved; truss type guardrails are designed on the two sides of the trestle; and safety of a vehicle in the passing process is ensured.
