Long Reach Telescopic Arm Two Section Hydraulic Telescopic Boom for 6-36 Ton

The excavator telescopic arm consists of a stable base, a movable sliding section, a wire rope, and a hydraulic extension cylinder. Adjusting the sliding components allows precise control over the digging radius and vertical reach. Commonly used with a bucket, it is ideal for deep excavation projects, handling materials such as soil, sand, and coal.

Constructed with LG700 for the main sections and Q355B for supporting parts, the two-section boom is both lightweight and resilient. Notable specifications:

• 22-ton bucket cylinder for superior power

• Upgraded reel with enhanced spring plates

• Multi-layer reinforcements at bearing points

• LG700 steel box structure for increased strength

• Reinforced pivot end for added durability under excavation stress

• Reinforced Durability – Constructed from high-grade steel, ensuring a balance between strength and weight reduction.

• Deeper Digging Performance – Our arm provides 20 cm additional depth compared to standard designs.

• Vibration Reduction – The double-slider system stabilizes the telescopic cylinder, improving operational reliability.

• Hose Protection Enhancement – A two-layer casing keeps the hydraulic hose secure and limits wear.

• User-Friendly Maintenance – The bucket cylinder is externally mounted, making servicing easier.

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.
