 Efficient and reliable pumping
• High configuration imported pump and motor ensure the reliability and stability of the hydraulic and electrical systems.
• The imported hydraulic oil filter ensures the cleanness of the hydraulic system and long service life of the hydraulic components.
• The adopted latest closed and variable hydraulic system of constant power has the full power takeoff, featuring 3MPa less in pressure loss, and saving the energy by 10%.
• The unique product in the hydraulic system-SN valve reduces the impact when changing the direction and settles the common issue of vibration of the pump, increasing the stability of the machine.
• The adopted S type change valve and new center pumping system feature higher efficiency, longer service life and more convenient maintenance.
• Keep the inclination of the optimized hopper in the best position, and adopt the automatic rotation device which could keep the hopper from blocking by the stone.
• Delivery pump, reducer piper and glasses board and cutting ring adopt the high-abrasive material, prolonging the service life of the wearing parts.
Load sensing electro-hydraulic proportional control valve features excellent fine mobility and quick response.
• Intelligent experience
• X outrigger and one side operation.
• High and low pressure change freely.
• Multiple boom folding methods such as ”R” and “RZ” type features large placing area.
• The imported grease and oil automatic lubricating system prolongs the service life of the machine and features easy maintenance. The system could automatically lubricate the key points with hydraulic oil.
• The automatic withdrawing technology of trough in concrete piston ensures easier and faster replacement of the piston.  
• Precise remote control and receiving device could get 150m remote control, decreasing the operation labor and ensuring the safety of the worker.
• Intelligent electric control box records the working pressure and temperature, and the engine rpm of the truck pump, ready for check and repair. Meanwhile, it adopts the energy saving technology.
• The warning device equipped on the placing boom realizes the information quick delivery among the workers, ensuring the safe and efficient operation.
• The application of night viewing gradienter and outrigger wide light ensures the safe operation of the machine.
