An excavator telescopic arm consists of a stationary framework, a sliding extension, a steel rope, and a hydraulic telescoping cylinder. The digging depth and operational reach can be optimized by adjusting the number of sliding segments. Paired with a bucket, it efficiently excavates deep areas for material handling like soil, sand, and coal.
The two-stage boom is made of LG700 for robustness, while Q355B ensures a lightweight yet strong structure. Key advantages:
-
22-ton capacity bucket cylinder
-
Enlarged spring plates in the reel for durability
-
Multi-layer bearing reinforcement
-
High-strength LG700 steel box structure
-
Reinforced pivot end to withstand greater excavation pressures
High precision machine of Zhonghe Machinery Manufacturers
Large, floor-mounted double-sided boring and milling lathe:
- Increased Precision and Consistency: The double-sided boring and milling lathe enhances operational accuracy and consistency.
- Post-Welding Process: After welding, the machine bores through the hole, ensuring the parallelism and verticality of the shaft.
- Main Responsibility: This machine is primarily used for post-welding boring of large and small arms and buckets to ensure accuracy.
- Simultaneous Boring: The double-sided boring lathe performs boring on both sides at the same time, guaranteeing even accuracy.

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.
