Excavator Telescopic Boom Telescopic Stick For River Port Dredging Work

A telescopic arm for excavators comprises a fixed base, a sliding assembly, a steel wire rope, and a hydraulic cylinder. Modifying the number of sliding bodies allows for flexible excavation depth and working range. Combined with a bucket, it excels in deep pit digging for materials like soil, sand, and coal.

The two-section boom is primarily made of LG700 for strength, with Q355B ensuring lightweight stability. Distinctive features include:

• A 22-ton bucket cylinder for maximum force

• A reinforced reel with expanded spring plates

• Multi-layer reinforced bearings for longevity

• LG700 high-strength steel box structure

• Strengthened pivot end for handling extreme loads

• High-Strength, Lightweight Design – We use premium high-strength plates that enhance durability while minimizing the excavator's load.

• Superior Digging Depth – Compared to competitors, our telescopic arm reaches approximately 20 cm deeper for the same arm length.

• Enhanced Cylinder Stability – A double-slider design in the telescopic cylinder reduces vibrations and provides additional support, lowering the risk of cylinder failure.

• Optimized Hydraulic Hose System – The double-layer casing for the bucket cylinder hose eliminates pipeline vibrations and simplifies hose replacement.

• Convenient Maintenance – The external bucket cylinder placement allows for quick and easy replacement and maintenance.

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.
