An excavator telescopic arm consists of a stationary framework, a sliding extension, a steel rope, and a hydraulic telescoping cylinder. The digging depth and operational reach can be optimized by adjusting the number of sliding segments. Paired with a bucket, it efficiently excavates deep areas for material handling like soil, sand, and coal.

The two-stage boom is made of LG700 for robustness, while Q355B ensures a lightweight yet strong structure. Key advantages:

• 22-ton capacity bucket cylinder

• Enlarged spring plates in the reel for durability

• Multi-layer bearing reinforcement

• High-strength LG700 steel box structure

• Reinforced pivot end to withstand greater excavation pressures

• High-Tensile Material – Fabricated with high-strength plates, ensuring longevity and reduced equipment strain.

• Unmatched Depth Capacity – Offers 20 cm deeper excavation ability than standard competitors.

• Dual-Slider Efficiency – This system minimizes telescopic cylinder vibrations, increasing its lifespan.

• Hydraulic System Protection – The double-layer casing prevents premature pipeline wear.

• Quick & Simple Maintenance – The externally placed cylinder allows for seamless 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.
