Detail Information
mobile diesel concrete boom pump
Instruction:

1.Diesel mobile concrete placing boom pump adopted self-made chassis, no need the number plate. It is the non-standard machine with easier marketing procedure and without high import tariff. 


2.The chassis can be hydraulic driven, speed change, shift and steering by the hydraulic motor, gearbox and oil cylinder, and also can be driven by motor tractor.


3.Through finite element analysis, dynamics analysis, calculation and experiment, on the basis of accurate data support, adopted high strength low alloy steel plate,  all materials and welds pass 100% NDT. Ensure the rationality and reliability of the X-type brace and arm structure.


4.The engine speed is controlled automatically, when the arms moving the rev is 1100-1200rpm, when pumping, the rev changes with the displacement between 1200-1700rpm, low rev with low displacement while high rev with high displacement. The engine torque is the largest during this rev range, so that the fuel is economical and efficient.

Main Parts:
concrete boom pump truck fittings
Hydraulic rubber hose joints
The hydraulic rubber hose joints are products of American Eaton, insuring the safety and no leakage of hydraulic system.
boom concrete pump truck main pump
Main oil pump
Main oil pump adopts REXROTH or Japanese KAWASAKI variable plunger pump to insure system stable and reliable, with functions of overpressure and overflow to effectively protect main oil pump and diesel engine.
boom concrete pump hopper
Hopper
Latest version whole stamping hopper is new optimization on inner line, suction rate improved by 20%, no sticking materials, easy to clean.
concrete boom pump truck pipeline
Pumping Pipeline System
Pumping pipeline adopt composite double wear-resisting materials,wear resistation degree can reach 50,000 cublic meters.(m³)
boom concrete pump truck hydraulic pumping system
Pumping hydraulic system
Overall hydraulic control system and oil pressure signals make operation more simple and reliable,improve the swing cylinder reversing speed and reduce the reversing impact.At the same time,the large oil cylinder reversing moment action could be accelerated and the concrete cylinder would be fully filled, making concrete output continuous and smooth.
concrete boom pump truck jib system
Jib structure system
Jib structure system is based on the finite element analysis, dynamic analysis and test, and the accurate date support.High strength low alloy steel plate,all materials and welding line by 100% non-destructive technology ensure the jib structure reasonable and highly reliable.

Hydraulic system of jib structure and support legs
Electro-hydraulic and manual multiple valves ensure wireless remote control and manual control in case of emergency.

Transfer case
We adopt imported transfer case.
Feartures:

1.Adopted self-made chassis, no need the number plate. It is the non-standard machine with easier marketing procedure and without high import tariff. 


2.The mobile placing boom pump chassis can be hydraulic driven, speed change, shift and steering by the hydraulic motor, gearbox and oil cylinder, and also can be driven by motor tractor.


3.Through finite element analysis, dynamics analysis, calculation and experiment, on the basis of accurate data support, adopted high strength low alloy steel plate,  all materials and welds pass 100% NDT. Ensure the rationality and reliability of the X-type brace and arm structure.


4.The engine speed is controlled automatically, when the arms moving the rev is 1100-1200rpm, when pumping, the rev changes with the displacement between 1200-1700rpm, low rev with low displacement while high rev with high displacement. The engine torque is the largest during this rev range, so that the fuel is economical and efficient.


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 placing boom 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.
