Global Case

Advantage

With the special chassis for the development of rural market and the 2.3 meters width, it can easily adjust to and pass through the narrow and sludge rural roads. Using flexible four arm design, fabric ranges 20% higher than three-arm. At the same time it also applies the unilateral support technology in order to easily perform in a narrow construction site.
● The construction is especially for the new rural middle-low levels.
● The manufacture of short arm frame designed for high-speed rail construction.
● The design of national IV emission standard for energy conservation, and environmental protection
● Hydraulic automatic reversing of pumping system is for simple maintenance.
● 18-35 meters arms can move up and down, in accordance with high-speed rail laws.
● X-legs is designed to lead more safe and stable operation.
● Extremely high performance price ratio and use reliability help the party make profits.

Specification

Chassis and power system: Using truck chassis of Chinese FAW, Beiqi Foton, Dongfeng, featuring strong carrying ability, good dynamic performance and low fuel consumption; you can choose the installation of power alone or the chassis power, the Separate power of independent research and development possesses the features of fuel economy, reduce energy consumption, easy maintenance.
Pumping hydraulic system : full hydraulic control of the hydraulic system , oil pressure transfers signal, making the operation become more simple and reliable, improving swing cylinder commutation speed and reducing the impact of change , meanwhile the speed of large cylinder change is instantly accelerated, the move can full the concrete cylinder, making the process of material continuity and evenly.
The boom and pumping hydraulic system: the arm uses the load-sensitive proportional control system, so as to control the speed of the boom freely and achieve excellent operating performance; it can achieve infinitely variable remote control but also achieve an emergency manual operation in case of emergency; legs and the oil boom switch directly to avoid the misuse and ensure the working security.
The boom: By the finite element analysis, dynamic analysis and experiment and on the basis of accurate data, materials adopt the high strength low alloy steel plate, and all materials and welds passed by 100% non-destructive testing so as to ensure the rational boom structure and high reliability.
Note: Preferring to choose the matching tops diesel engine: Yuchai, Cummins, Revo.
