52M Concrete pump truck is combined with high reliability, economy, safety and durability. It has reasonable collocations for the chassis system, power system, control system, hydraulic system and pumping system. With the characteristics of flexible foldable arms, little space occupying support legs, easily movable chassis, equipped with H/L pressure switch, high outlet pressure, the whole concrete pump truck is more flexible, reliable, stable and safe. It is the top-choice concrete equipment widely used in tunnel, airport, seaport, high-speed rail site, beam field, bridge construction projects and so on.
JIB SYSTEM
- It is based on the finite element analysis, dynamic analysis and test, and the accurate data 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.
- Arms with speed stepless adjustment, pressure compensation and load sensing proportion control system ensure the arm running freely and excellent operating performance.
Hydraulic System
- PUSH oil pumps and valves from TAIFENG ensure the concrete pump truck high efficiency, long service life, high stability and excellent continuous working performance. World famous Oil pipes and Joints with superior performance enlarge the system flows and avoid oil leakages.
- Pumping system is open circuit, no shock, no peak value and ideal temperature control.
- Oil cylinder piston rod seals adopt imported combined seals with good sealing effect and strong waterproof performance. Piston seals adopt multiple durable piston rings.
- Swing oil cylinders adopt piston cylinders sealed by 0K seals with good sealing and buffering effects, ensuring long time and stable working.
LUBRICATING SYSTEM
- Lubricating system adopts fully automatic oil supply and multiple filtration technology, effectively extending the service life of wearing parts.
- Oil pumps on arms adopt axial piston pumps with load sensing variable. The output could be according to the actual working needs, reducing power loss and system heating
Electric Control System
- Siemens relay, high reliability and automation.
- Panel control and wireless remote control devices are both equipped and easy to operate. Shanghai Jijing remote controller imported from Germany accord with the principles of human engineering design with beautiful shape, easy operation and flexibility.
- Multiple alarming devices ensure machine working with high security.
- Oil energy-saving control: Energy-saving control technology, researched and developed by our company, ensures the output power of engine matching automatically along with load changing, making fuel loss to a minimum.
- Friendly man-machine interface: High humanized man-machine interface could quickly enter the information page you want to browse and get all the information you need.
- Safe operation control technology: Effective error-proof operation control design ensures the system more reliable and safe.
