21m 3 arms mini truck pump with placing boomÂ
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.
