Heavy-duty Two-section Telescopic arm Excavator Telescopic Boom for construction
What is an excavator telescopic arm
This product mainly consists of a fixed body, sliding body, steel wire rope and a telescopic cylinder. By changing the number of sliding bodies, an ideal working radius and vertical excavation range can be achieved. Generally used in combination with a bucket, it can complete deep pit excavation tasks, such as grabbing soil, sand or coal.
The two-section telescopic boom is made of LG700, and other parts are made of Q355B, which is lighter and more durable. We use 6mm thickness.
* 22-ton strong bucket cylinder * The reel adopts enlarged spring piece * Bearing part with multi-layer reinforced * The box is made of LG700 high strength material * The pivot end is reinforced with multiple layers to withstand greater excavation forces.
What are the advantages of our telescopic arm?
1. We use high-strength plates, which are light and durable, and have low excavator load.
2. For arms of the same length, our arm's digging depth is about 20 cm deeper than that of other manufacturers.
3. The double slider design of the telescopic cylinder reduces the vibration of the cylinder and provides support for the cylinder, reducing the failure rate of the cylinder.
4. The hose of the bucket cylinder adopts a double-layer casing design, making pipeline vibration a thing of the past, and it is easy to replace the hose.
5. The bucket cylinder is exposed outside the barrel, which is convenient for replacement and maintenance of the bucket cylinder.
Two Section Telescopic Arm Configuration
1. A set of telescopic arm 2. Eight high-pressure hoses
3. Nine pins
4. A standard bucket
5. A two-way foot switch
6. A bucket cylinder
7. A set Linkage

Application of Two-section Telescopic Arm
1. Deep Excavation: Ideal for digging deeper than standard arms can reach, such as in trenching, foundation work, and mining.
2. High-Reach Demolition: Useful in demolition projects where controlled dismantling of taller structures is necessary.
3. Confined Spaces: Helpful in areas with limited space for maneuvering, such as urban construction or work under bridges.
4. River and Canal Dredging: Extends the reach for dredging operations in rivers, canals, or ports, improving efficiency and safety.
5. Material Handling: Used in handling bulk materials like sand, gravel, or waste in transfer stations and recycling facilities.
6. Forestry and Agriculture: Sometimes applied in forestry for handling logs or in agriculture for tasks requiring a longer reach over uneven terrain.
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.
