Two-stage hydraulic telescopic arm Excavator long reach telescopic boom for CAT Komatsu
What is an excavator telescopic arm
A telescopic arm for excavators includes a fixed base, a sliding extension, a wire rope, and a hydraulic telescoping cylinder. By varying the number of sliding sections, the operational reach and excavation depth can be customized. It is commonly paired with a bucket for deep digging applications, including handling soil, sand, and coal.
The two-section telescopic boom is crafted from LG700 steel for high strength, with Q355B used for additional components to maintain a balance of durability and reduced weight. Features include:
22-ton bucket cylinder for enhanced digging force
Strengthened reel with enlarged spring plates
Multi-layer reinforced bearings for extra durability
LG700 steel box construction for high load capacity
Reinforced pivot end to handle greater excavation forces
What are the advantages of our telescopic arm?
Premium Steel Construction – Engineered for both strength and reduced weight, improving efficiency.
Extended Digging Reach – Our model digs 20 cm deeper than standard alternatives.
Stable Cylinder Performance – A double-slider design ensures consistent support, reducing vibration-related failures.
Enhanced Hose Security – A dual-layer casing eliminates unnecessary hose movement.
Easy Replacement & Repairs – The external bucket cylinder simplifies maintenance tasks.

Application of Two-section Telescopic Arm
Deep Digging Projects – Facilitates excavation in projects requiring extended reach.
Building Teardown at Heights – Supports controlled demolition of multi-level structures.
Space-Constrained Excavation – Performs efficiently in tight or restricted sites.
Hydraulic Dredging Work – Used for clearing silt and debris from rivers and ports.
Efficient Bulk Material Transfer – Essential for managing aggregates and scrap materials.
Forestry & Large-Scale Farming – Useful for lifting and transportation in rural industries.
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.
