A telescopic arm for excavators includes a fixed base, a sliding extension, a wire rope, and a hydraulic telescoping cylinder. By varying the number of sliding sections, the operational reach and excavation depth can be customized. It is commonly paired with a bucket for deep digging applications, including handling soil, sand, and coal.

The two-section telescopic boom is crafted from LG700 steel for high strength, with Q355B used for additional components to maintain a balance of durability and reduced weight. Features include:

• 22-ton bucket cylinder for enhanced digging force

• Strengthened reel with enlarged spring plates

• Multi-layer reinforced bearings for extra durability

• LG700 steel box construction for high load capacity

• Reinforced pivot end to handle greater excavation forces

• Premium Steel Construction – Engineered for both strength and reduced weight, improving efficiency.

• Extended Digging Reach – Our model digs 20 cm deeper than standard alternatives.

• Stable Cylinder Performance – A double-slider design ensures consistent support, reducing vibration-related failures.

• Enhanced Hose Security – A dual-layer casing eliminates unnecessary hose movement.

• Easy Replacement & Repairs – The external bucket cylinder simplifies maintenance tasks.

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.
