A telescopic excavator arm includes a fixed section, a sliding mechanism, a steel cable, and a telescopic cylinder. By adjusting the sliding components, the reach and excavation depth can be tailored to specific needs. Often paired with a bucket, it is ideal for deep excavation applications such as soil, sand, and coal removal.

The two-section boom is made from LG700 for maximum durability, with Q355B used for structural balance. Unique features:

• High-powered 22-ton bucket cylinder

• Reinforced reel with larger spring plates

• Multi-layer support at bearing points

• LG700 steel box construction for improved strength

• Reinforced pivot end for enhanced excavation performance

1. Durable & Lightweight Build – Designed with high-strength steel, reducing weight without compromising toughness.

2. Increased Digging Range – Our design allows for an extra 20 cm depth over standard models.

3. Stable Hydraulic Cylinder – The double-slider structure reduces shaking, extending component longevity.

4. Reinforced Hose Design – A double-layer casing minimizes vibrations and potential damage.

5. Simplified Component Replacement – With an external bucket cylinder, repairs are fast and efficient.

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.
