What is an excavator telescopic arm
An excavator telescopic arm consists of a rigid main body, a sliding extension, a steel rope, and a hydraulic telescoping mechanism. Changing the number of sliding sections enables a customizable digging range and depth. When combined with a bucket, it facilitates deep excavation work for materials such as soil, sand, and coal.
The two-section boom is engineered using LG700 steel for high strength, while Q355B offers additional support for a lightweight build. Key characteristics:
22-ton bucket cylinder for superior performance
Enlarged spring plates in the reel system
Reinforced multi-layer bearings
LG700 steel box frame for optimal strength
Strengthened pivot point to withstand heavy excavation forces
High-Quality Steel Composition – Built from reinforced steel, achieving both strength and reduced mass.
Superior Depth Capacity – This arm provides 20 cm additional reach over similar products.
Cylinder Vibration Control – A dual-slider mechanism maintains smooth operation and minimizes breakdowns.
Double-Layer Hose Shielding – Reduces movement, enhancing the longevity of the pipeline.
Convenient Maintenance Access – The external bucket cylinder ensures easy replacements and servicing.

FAQ(Some frequently asked questions):
Q: Are you a manufacturer?
A: Zhonghe machinery offered a wide range of attachment parts for excavators and dozers. Such as long reach arm, demolition arm, telescopic arm, standard bucket, rock bucket, cleaning bucket, tilting bucket, etc. We know that the perfect combination of high-quality cast steel products and a moderate price is the key to the success.
Q: Is the length of the telescopic arm the total length or the digging depth?
A: The length of a two-stage telescopic arm refers to the digging depth. For example, a 14-meter telescopic arm means that the maximum digging depth is 14 meters, so it is called a 14-meter telescopic arm. The actual arm length is not only 14 meters.
