Performance characteristics of China Shandong Hongda concrete boom pump truck

1. The pump truck boom, outriggers, turret and turret support are made of fine-grained high-strength 700~900 Mpa steel plate, box-shaped structure, good strength and rigidity, light weight and low fuel consumption.

2. The electro-hydraulic proportional control boom stretches, the action is stable and can be slightly moved, and the balance valve buffer self-locking function can well protect the safety of the boom system. The stepless speed regulation RZ folding boom system has a fast unfolding speed and can be used for construction in narrow construction sites. Each boom can be operated independently or jointly, which can eliminate any construction dead angle. With remote control device, light weight, easy to carry, only use two handles to operate, the cloth rod can be accurately positioned.

3. Electric proportional constant power variable closed hydraulic system, full power power take-off, no frequent reversing valve group on the main oil circuit, pumping reversing is hydraulic flexible reversing, and the pressure loss is small compared with the open circuit. The impact is small and the operation is stable, which can effectively improve the service life of the boom system.

4. The pumping volume has a stepless adjustment function, which can meet the requirements of different output volumes

5. Using Italian LEONESSA slewing bearing, hydraulic motor + planetary gear reducer drives the boom to 370° slewing, the braking effect is good, there are mechanical limit and electrical limit double protection.

6. The pumping system is signaled by a proximity switch and controlled by a PLC microcomputer. The main electrical components are selected from Siemens, LG, Schneider and other brands.

7. All hydraulic valves and oil pump oil motors adopt high-quality products from well-known companies such as German Rexroth and HAWE. The engine-transmission-drive shaft-transfer box-oil pump-proportional valve-cylinder links are matched reasonably.

8. The boom is stable during pumping, and the tail pipe shakes little, so it can be poured accurately.

9. All operations can be achieved through wireless remote control and wired remote control. Two sets of independent operating devices ensure reliability and safety.

10. In order to prevent accidents, emergency brake switches are installed on the pump truck main control board, the remote control box and the left and right sides of the pump truck.

11. It adopts Japanese Isuzu chassis, Euro IV emission, and has passed my country's 3C strong inspection certification, which is energy-saving and environmentally friendly. There are 14mm reinforcing plates on the top and bottom of the frame, and the actual section height is 348mm, which is our company's specific chassis for pump trucks.

12. Adopt S-type reversing valve, hard alloy glasses plate and cutting ring, and equipped with rubber spring to automatically compensate the end face gap, ensuring good sealing performance.

13. It has the functions of positive pump, reverse pump, jog, etc., plus a discharge device that can be opened quickly, making it very convenient to clean the pipeline. The mixing can rotate forward and backward, which can relieve the jam of aggregate in time.

14. The lubrication of the hopper and the concrete cylinder is automatically lubricated, and it is lubricated when pumped.

15. The main cylinder seal is the product of American Parker Company. The inner wall of the concrete cylinder is thickened and hard chrome layer, which can reliably ensure that the pumping of 20,000 cubic meters will not cause problems.
