What is an excavator piling arm?
The excavator piling arm is a device on the excavator used to install and operate poles, such as reinforced concert piles, steel sheet piles, etc. It is usually used in combination with a vibrating hammer with a large arm and a small arm guard. The excavator piling arm is powered by the excavator's hydraulic system and can insert piles vertically into the ground to fix or reinforce the structure.
Standard Configuration
1 set boom and arm, 3 stop valves, 9 high‑pressure hoses.
Advantages of Pile Driving Arm
1. Standard material Q355B; Q690D high‑strength steel available upon customer’s request.
2. Straight‑type boom design, lighter self‑weight to achieve higher pile‑driving and extracting force.
3. Sectional boom pipeline layout for easy transportation & field maintenance.
4. Reinforced plates & thicker plates at crack‑prone positions.
5. Optimized opening angle 160°, lifting angle 88‑90°, avoid collision against slew motor.
6. Under‑mounted bucket‑cylinder design to counteract reaction force, reduce counterweight requirement & save fuel consumption.
7. Two optional styles: Mainland style (pipes on top) and Southeast‑Asia inner‑sleeve style
Piling Types
Steel Sheet Pile, Concrete Pile, Photovoltaic Pile, U-Shaped Pile, Casing, Channel Steel Pile
Different sheet piles apply to various construction scenarios
1.Sheet piles and channel steel piles
Steel cofferdam for bridge construction, support for sewage pipelines, permanent river‑bank reinforcement, foundation caps for real‑estate projects, roadside landslide prevention, basement and sewer construction.
2.Casing
Used together with rotary drilling rigs to avoid hole collapse during drilling, widely applied in bridge building and real‑estate construction.
3.Concrete piles
River bank reinforcement and solar power project piling work.

ZHONGHE triple quality control system
1.The first system is the technical design drawing review mechanism.
2.The second system is the semi-finished product review mechanism.
(each process has a detection testing for the previous process)
3.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 the installation 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
