CHARACTERISTIC
Easy to maintain
70 Ton Pipelayer SP70Y structural parts inherit the excellent and stable quality of SHANTUI mature products.
The wiring harness is branched with seamless corrugated tubes and shunts, with a high degree of protection.
The core electrical and hydraulic parts are imported products, with stable and reliable quality and high reliability.
Operating performance
The control of the working device consists of variable amplitude control, hoisting control and counterweight control. The hydraulic reversing valve is controlled by a pressure-reducing pilot control valve, which is simple in control, flexible and labor-saving, has good fine-tuning performance, and is easy to install on the 70 Ton Pipelayer SP70Y body.
The hook and the boom are controlled on a joystick, and the counterweight is controlled by a separate joystick, which is convenient and quick to operate under various working conditions, achieves good jog performance, ensures the accuracy requirements of users, and improves work efficiency.
The hydraulic motor of the hook and boom winch has extremely high volumetric efficiency, and the excellent balance valve eliminates the secondary slip of the winch and the jitter of the empty hook. In addition, the clutch in the hitch winch implements the free-drop hook function.
Working adaptability
70 Ton Pipelayer SP70Y chassis has good stability, low average fuel consumption and high economy.
The boom has a wide working range and the hook lifts quickly.
Large bearing capacity, large lifting weight and high work efficiency.
The hook, boom and counterweight can realize stepless speed regulation and combined movement.
Both the hook and the boom winch adopt three-stage planetary gears for deceleration and torque increase, with high safety factor and high mechanical efficiency.
The machine is equipped with a torque limiter system to monitor the running status in real time to ensure safe lifting.
Power Systems
The Chongqing Cummins bulldozer engine installed in 70 Ton Pipelayer SP70Y adopts high-efficiency fuel injection pump, which has the characteristics of high performance, mature and stable quality, high social ownership, strong component versatility, and low maintenance cost.
