two-section telescopic boom for excavator excavator extendable boom arm
What is an excavator telescopic arm
A telescopic excavator arm includes a fixed section, a sliding mechanism, a steel cable, and a telescopic cylinder. By adjusting the sliding components, the reach and excavation depth can be tailored to specific needs. Often paired with a bucket, it is ideal for deep excavation applications such as soil, sand, and coal removal.
The two-section boom is made from LG700 for maximum durability, with Q355B used for structural balance. Unique features:
High-powered 22-ton bucket cylinder
Reinforced reel with larger spring plates
Multi-layer support at bearing points
LG700 steel box construction for improved strength
Reinforced pivot end for enhanced excavation performance
What are the advantages of our telescopic arm?
Durable & Lightweight Build – Designed with high-strength steel, reducing weight without compromising toughness.
Increased Digging Range – Our design allows for an extra 20 cm depth over standard models.
Stable Hydraulic Cylinder – The double-slider structure reduces shaking, extending component longevity.
Reinforced Hose Design – A double-layer casing minimizes vibrations and potential damage.
Simplified Component Replacement – With an external bucket cylinder, repairs are fast and efficient.

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.
