Truck-Mounted Line Concrete Pump / Concrete Truck (ZLJ5120THB)
Ａ, Hydraulic system
①The vehicle adopts double-pump double-circuit open hydraulic system, the main pump oil circuit and S valve swinging oil circuit are independently, this simples the system, prolong the service life of components, gain higher reliability and is convenient for checking and solving faults.
②For switching needs of the pumping circuit, the pilot operated directional valve with external control pressure-reduced effectively avoids shock during switching; the result is a steady and reliable system.
③Pumping circuit is protected by a relief valve; moreover the oil pressure of the main oil pump can be shut off automatically when system is overpressure, so the main hydraulic pump can acquire multistage reliable protection at on time.
④The switching circuit driven by the constant pressure pump can realize big switching strength and energy-saving at the same time.
⑤All pipes are cone sealed; it can ensure high reliability on sealing of tube connections.
⑥The adoption of high and low voltage reverse valve avoids troubles of pipe dismantling and oil filling.

Ｃ, Mechanical (mixing) distribution valve system
①The design for key parts of hoppers, S valve and etc. Adopts I-DEAS program to finite element calculate its load condition, calculate construction rigidity and stress concentration. The optimized hopper and S valve system can effectively avoid the following phenomena like hopper distortion and shaft break of S valve during conveying under high pressure, 2000 Zoomlion pumps that were put into market have well proved that.
②The mixing mechanism is particularly designed that hydraulic motor is completely separated from bearing seat, thus the motor will not be influenced in case of sealing failure. Meanwhile, large capacity motor is equipped to ensure that the mixing moment is enough, and normal mixing would not be disturbed even when materials are in bad conditions.
③Wear parts like glass plate and cutting ring etc. Have long service life up to 20000 m3. Service life of Zoomlion glass plates and cutting rings are 50% longer than other companies in domestic industry in the competition in construction site of Shenzhen Post and Telegraph Building.

| Imported rubber hose | |
|
1, Rubber hoses are imported from foreign companies. Joints are of international standard imported ones, thus avoid system leakage. |
|
| optimized design of boom structure | |
|
1, Small impaction 2, Smaller dither amplitude 3, Crake is controlled to the utmost. 4, Good artistic and tenacity in material welding. |
|
| glass plate and cutting ring | |
|
1, It can bear high-strength work, meanwhile can prolong service life of wear parts, and reduce impaction to booms. 2, Maybe you have noticed that the pumping frequency of Zoomlion new truck-mounted concrete pump is different from other brands, that is the reason why it can bear high-strength work but prolong service life of wear parts and reduce impaction to booms. The cost it saved is not only a little. You may also have noticed that the delivery pipes, taper pipes, glass plates and cutting rings are all made of anti-weary materials, thus greatly improve their service life and reduce the maintain cost. It has been proved by customers that the service life of glass plates reach 130000 m3, and straight pipes reach 30000m3. |
|
| Piston fast-replace technology | |
|
1, Time saved in fast-replacing of piston turned into money. Zoomlion new truck-mounted concrete pump has two shining points: the first one, it shortens the time of piston-replacing from 120 minutes to 15 minutes; second, maintenance period of hydraulic system is shortened.

|
| hydraulic system | |
|
1, Suitable positioning.
2, Mall impaction, oil temperature of non-peak pressure system is just right, and it reduced leakage to the utmost. |
|
| Motion graph of hopper, distributing, pumping and mixing | |
|
1, Further match the pumping, distribution, hydraulic system and power, fully exerts its efficiency. The systems can work steady, and the cost was obviously reduced.
