    Technical Advantage:

    1.Φ230 delivery cylinder and Φ125 oil cylinder, low requirement for concrete. Both to meet the needs of low pressure large displacement pump, but also to achieve high pressure small displacement car replacement’s needs.

    2.According to finite element analysis, dynamic analysis calcuating and testing, based on the accurate data support, materials using high strength low alloy steel plate. All the materials and welds are through 100% NDT,  to ensure that the X type leg and arm frame structure is reasonable and reliable.

    3.The engine speed automatic control, speed change with the displacement in the 1200-1600, low displacement with low speed, large displacement with high speed, this speed range is the largest part of the engine torque, fuel economy and efficiency.

    4.The main valve group adopts double pump double loop control of high and low pressure switch valve block, high and low voltage switch a key to complete, do not need to stop the pump, and the circuit is simple, low failure rate, easy maintenance. The main oil cylinder is supplied by the main oil pump, and the tilt cylinder is supplied by the gear pump with accumulator. The pump displacement can be less than 5 per hour, the maximum can reach more than 100 cu meters. Individual manufacturers by the main oil pump at the same time as the main oil cylinder and the cylinder oil supply, can not achieve a small displacement pump: the main pump displacement is very low, s tube swing also correspondingly slow, can not pump.

    5.Dual synchronous lubricating system. when working, the swing valve control oil drive, when not working, can push the rocker manual lubrication. Circulation port can be a bearing size hopper seat lubrication, synchronization can be sent to the piston pump, the piston’s life increased to above 30 thousand cu meters.

    6.The arm frame adopts the load sensing proportional multi way valve, the movement speed is stepless regulation, the speed is easy, the operation performance is excellent. Not only can realize the remote control, but also can realize the emergency manual operation. Mixing and supporting legs by the gear pump oil, with the pressure relay can achieve automatic mixing and reverse, to prevent large stones stuck blade.
