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

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.
Q: What material is the telescopic arm made of?
A: The arm tube of the telescopic arm is made of a690 or HG785 material, and the material of other parts is a355B material.
Q: What are your terms of payment?
A: We prefer T/T (50/50) through Ali Credit Insurance as a trial order.
Q: Are you always delivered on time?
A: We can't promise about the sea freight but what we can do is shorten our lead time while keeping the same quality level. So there will not be any problem even if the sea freight is delayed for a couple of days.
