Heavy Duty Excavator 18M Piling Boom and Arm for 35-50 Ton Excavators for Foundation Construction

The angle between boom and horizon can reach 88°,The angle between boom and arm can reach 160°

1. Comparing with the same length pile driving arm, ours can pile higher.

2. Adopt 90 degree elbow joint to avoid hose bending and increase it service life

3. The box has built-in transverse and vertical reinforcement ribs to improve pile driving boom tensile strength

4. Seamless precision steel pipe

5. Centralized lubrication system

6. three layers with four passes welding

7. The boom seat sleeve adopts all in one molding process

8. Graphite alloy copper sleeve

9. Hydraulic pipelines section design, convenient for later maintenance

10. Multi-layer reinforcing rib plate at the stress place, more firm, integrated molding

11. The back bushing of the pile arm is wrapped by the whole board to avoid falling off

Post-welding Testing
Accuracy Testing
Weld bead testing

Operation Testing

The first system is the technical design drawing review mechanism
The second system is the semi-finished product review mechanism,(each process has a detection testing for the previous process)

The third system is the finished product testing.
(Before painting, the overall inspection is carried out to check whether the design size matches the welding size, and whether theinstallation size meets the design requirement.)
To sum up, every single ZHONGHE product has been passed the above three-stage inspection system to ensure that is qualified before shipping.
