Pipelayer AST SP25Y

Easy maintenance: The structural parts inherit the excellent quality properties of SHANTUI's advanced products, with excellent stability of quality indicators; Seamless corrugated casing pipes are used for laying electrical wiring, branch pipes for branching wires, providing a high level of protection; The main electrical and hydraulic elements adopt imported products, ensuring stable quality and high reliability. Performance characteristics: The control of the working equipment includes reach change control, lifting control and counterweight control, the control is realized by controlling the hydraulic changeover valve with the pilot-operated pressure reducing valve, ensuring simple and easy operation with the least expenditure of effort, good fine adjustment capability, convenient installation; The load hook and boom are controlled by the same control lever, the counterweight is controlled by a separate control lever, which makes the work in different operating conditions more convenient and faster, with a large slow movement capability, making it possible to meet the user's requirements for accuracy and increase work efficiency; High volumetric efficiency of hydraulic motors of cargo and switch winches and high-quality balance valves solve the phenomenon of secondary sliding of winches and empty shaking of unloaded; and the clutch of cargo winch realizes the function of free lowering of the hook. Adaptable ability to work: High chassis stability, low average fuel consumption, high efficiency; Large working range of the boom, high lifting/lowering speed of the cargo hook; High stability of movement under load, large lifting capacity, high working efficiency; Stepless speed control and joint action of the cargo hook, boom and counterweight can be realized; Increasing the torque of the cargo and switch winches, a three-stage planetary gear is used inside the gearbox housing, having a high level of safety, high mechanical efficiency; The machine is equipped with a torque limiter system, this allows real-time monitoring of the operating status, ensuring the safety of lifting.
