Customizable Three-Section Telescopic Arm Excavator Extension Arm Long Reach Boom Special Construction Machinery Part
What is an excavator telescopic arm
A telescopic arm for excavators consists of a stationary frame, a sliding mechanism, a wire rope, and a telescopic hydraulic cylinder. The excavation depth and operational radius can be adjusted by modifying the number of sliding sections. It is often equipped with a bucket for digging deep pits and handling materials like soil, sand, and coal.
The two-stage telescopic boom utilizes LG700 steel, while Q355B is used for other structural components to ensure durability and reduced weight. Features include:
22-ton heavy-duty bucket cylinder
Enlarged reel with reinforced spring plates
Multi-layered reinforcement at the bearing points
LG700 high-strength steel box structure
A strengthened pivot end for improved resistance to excavation forces
High-Strength, Low-Weight Build – We use reinforced steel to improve durability while reducing excavator stress.
Enhanced Depth Capability – Our arm reaches about 20 cm deeper than other brands of similar length.
Advanced Cylinder Support – The double-slider mechanism ensures better stability, reducing vibrations and prolonging cylinder life.
Upgraded Hose System – A protective dual-layer casing prevents excessive movement, making hose replacements simpler.
Effortless Servicing – The external bucket cylinder placement ensures hassle-free maintenance and part 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.
