The invention discloses a full-hydraulic control derrick trailer which comprises a trailer frame, a wheel axle assembly, a ladder assembly and a hydraulic control system. The trailer frame is dividedinto an upper layer, a middle layer and a lower layer and sequentially comprises a main frame body, a limiting beam and a lifting beam from bottom to top. The limiting beam is fixedly connected with the main frame body, and the lifting beam is fixedly connected with the middle of the limiting beam. The hydraulic control system comprises a supporting leg oil cylinder, a lifting oil cylinder, a steering oil cylinder and a hydraulic station. The supporting leg oil cylinder is used for supporting and lifting a trailer frame, the limiting beam is hinged to the two ends of the lifting beam through the lifting oil cylinder, the wheel axle assembly is installed on the main frame body and controls steering through the steering oil cylinder, and the hydraulic station is fixed to the main frame body.Kinetic energy is provided for the supporting leg oil cylinder, the lifting oil cylinder and the steering oil cylinder. The ladder assembly is fixed on the main frame body. The trailer adopts full-hydraulic automatic operation, the operation is convenient, trouble and labor are saved, and meanwhile, the trailer frame can be disassembled and assembled so that the trailer is convenient to process and transport.
