What is an excavator telescopic arm
An excavator telescopic arm is a specialized extension system comprising a rigid base, a sliding mechanism, a steel rope, and a hydraulic actuator for controlled movement. The adjustable sliding sections provide an extended working range and deeper excavation capacity. When equipped with a bucket, it enables efficient soil, sand, and coal extraction in deep excavation scenarios.
The two-section boom is constructed with LG700 steel for strength and Q355B for additional support, making it lightweight yet highly durable.
High-performance 22-ton bucket cylinder
Reinforced reel featuring enlarged spring plates
Robust multi-layer bearing assembly
Sturdy LG700 steel box structure for enhanced strength
Strengthened pivot joint for superior load resistance
Premium Steel Build – Crafted from high-grade reinforced steel, making it strong yet lightweight.
Increased Excavation Depth – Reaches up to 20 cm deeper than competing models.
Smooth Cylinder Operation – A dual-slider setup enhances stability and reduces component failures.
Advanced Hose Protection – Double-layer casing prevents excessive movement, improving durability.
Effortless Component Replacement – The externally mounted bucket cylinder simplifies repairs and maintenance.
| Excavator (ton) | Max Depth (mm) | Effective Length (mm) | Bucket Capacity (cbm) | Cylinder (ton) | Cylinder (ton) |
| 12-15 | 10000 | 8170 | 0.2 | 6 | 0 |
| 20-25 | 12000 | 8700 | 0.4 | 20 | 0 |
| 20-25 | 14000 | 10680 | 0.4 | 20 | 2 ton |
| 30-35 | 16000 | 12080 | 0.6-0.8 | 22 | 1 ton |
Application of Two-section Telescopic Arm
Deep Excavation Projects – Designed for foundation digging, underground construction, and mining operations.
High-Reach Demolition – Facilitates safe and precise removal of tall structures.
Tight-Space Maneuvering – Operates effectively in confined construction areas.
Waterway Dredging – Enhances efficiency in river, canal, and harbor maintenance.
Heavy Material Transport – Streamlines handling of bulk materials like gravel, coal, and sand.
Forestry & Farming Applications – Supports log transportation and large-scale agricultural tasks.
Since 2018, Kaiping Zhonghe Machinery Manufacturing Co., Ltd. has been dedicated to producing high-performance excavator boom arms and attachments, such as long reach booms, demolition arms, and custom buckets. Our products are trusted by customers in over 60 countries worldwide.
Operating from an 18,000 m² factory in Guangdong, we utilize advanced manufacturing technology and a highly skilled team of over 100 employees, including 50 professional welders and 30 experienced designers. With an annual output of 600 units, we focus on precision, durability, and customer-driven solutions.
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.
