deep foundation work hydraulic telescopic arm excavator telescopic stick

An excavator telescopic arm comprises a fixed section, a sliding component, a steel cable, and a telescopic cylinder. Adjusting the number of sliding bodies allows for an optimal digging radius and depth. Typically paired with a bucket, it efficiently excavates deep pits for materials like soil, sand, and coal.

The two-section telescopic boom is constructed with LG700 for durability, while other parts use Q355B for a lightweight yet strong structure. The design features:

• A 22-ton high-power bucket cylinder

• Enlarged spring components in the reel

• Multi-layer reinforced bearings

• A box structure made of high-strength LG700 steel

• A reinforced pivot end to endure higher excavation forces

• Lightweight & Durable – Made from high-strength steel, our design reduces excavator load while ensuring durability.

• Greater Digging Depth – Our telescopic arm extends 20 cm deeper than competing models of the same length.

• Double-Slider System – The dual-slider structure in the telescopic cylinder minimizes vibration and enhances stability, reducing failure rates.

• Reinforced Hose Protection – A dual-layer casing for the bucket cylinder hose eliminates pipeline vibrations and extends its lifespan.

• Easy Maintenance – The externally placed bucket cylinder allows for quick access and convenient replacement.

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.
