Affordable telescopic boom attachments for heavy machinery Durable telescopic boom solutions for construction sites
Product Description-------Excavator Telescopic Boom
What is an excavator telescopic arm?
An excavator telescopic arm is a versatile attachment that provides extra length to the boom. This adaptability enables operators to navigate complex job sites and perform tasks that would otherwise require repositioning the entire excavator.
What are your advantages?
Advantages of telescopic arms:
1. The three-section telescopic boom is made from lightweight yet
durable BS900E and Q355B materials.
2. A robust thickness of 6mm enhances its overall durability.
It includes nylon sliders and steel pulleys, with centrally
lubricated hoses for efficient operation.
3. The external pulley on the bucket cylinder allows for easy hose
maintenance and replacement.
4. This design separates hoses from the main rope to minimize
friction and maintenance needs.
5. Featuring a double-rope system, the arm remains secure even if the main rope experiences failure.

Three Section Telescopic Arm Configuration
1. A set of telescopic arm
2. Two high-pressure hoses
3. Two pins
4. One clamshell bucket
5. One two-way foot switch
Some installation instructions for telescopic arms
Our designs allow for interchangeable use of digging buckets and grab buckets.
The first one is clamshell bucket ,usually use for Subway deep digging project .
The second one is the grab bucket , compare to the clamshell bucket , the grab bucket have power
,can grab the stone.
The last is the standard bucket , use for telescopic boom the bucket need do the special design .

Telescopic Boom Arm Engineering Case
The telescopic arm of the excavator is suitable for the following working conditions:
- Limited Area Construction: The telescopic boom is ideal for construction tasks in areas with limited space.
- Deep Excavation Projects: It excels in deep excavation projects, such as basements and underground utilities.
- Demolition in Urban Environments: The boom allows for efficient demolition in densely populated areas without much repositioning.
- Tight Space Excavation: It is ideal for excavating in tight spaces that may be difficult to access with a conventional boom.
- Utility Installation: The telescopic boom can reach areas where it is difficult to access utility installations.
- Repair Work on Elevated Structures: It is very effective for maintenance and repair work on elevated structures, such as bridges.
- Heavy Lifting Tasks: The extension of the boom enables it to lift heavy materials in hard-to-access areas.
- Environmental Restoration: It can be used for environmental restoration projects that require precise excavation in tight spaces.

What is the purpose of beveling the long boom arm plate?
Most welding machines commonly used in the industry have a penetration depth of only 3mm. Since the thickness of our long arm plate is at least 8mm, without beveling, the welder would not be able to fully penetrate through the entire joint. This would result in weak welds, leading to issues such as weld cracking in the future.
We employ mechanical beveling, whereas other factories rely on manual beveling (as shown in the figure).

High precision machine of Zhonghe Machinery Manufacturers
Large Floor-Standing Double-Sided Boring and Milling Lathe:
- Improved Accuracy and Consistency: The double-sided boring and milling lathe enhances the precision and uniformity of operations, ensuring consistent results.
- Post-Welding Processing: After the welding process, the machine performs overall boring, ensuring the parallelism and perpendicularity of shaft holes.
- Primary Applications: Primarily used for post-weld boring of the boom, small arm, and bucket, ensuring the accuracy and proper alignment of the boom.
- Simultaneous Boring on Both Sides: The lathe performs boring on both sides at the same time, guaranteeing identical precision and consistency on both sides.

FAQ(Some frequently asked questions):
Q: Are you a manufacturer?
A: We are a manufacturer/supplier of excavator arms and attachments. We have a super large factory. The factory area is several times that of our competitors. It is the largest excavator attachment factory in Guangdong Province. It has complete production equipment and its products have been exported to more than 60 countries around the world.
Q: Why does the telescopic arm have the difference between a shell bucket and a grab bucket?
A: Generally, shell buckets are easy to use for silt and sand, and
can dig a large volume with higher efficiency. However, in general
sand and stone work, shell buckets have no digging force and are
limited by the opening, so the efficiency of shell buckets will be
reduced. Grab buckets are more suitable for this kind of work.
However, due to the overall weight of the grab bucket, the volume
of the grab bucket is generally smaller than that of the shell
bucket, but in work with more stones, the advantages of grab
buckets are more obvious.
Q:Is it better to use a single cylinder or a double cylinder for
the shell bucket equipped with a telescopic arm?
A:We always use the double cylinder design and never use the single
cylinder design. It has the advantages of low failure rate,
convenient maintenance, and less oil leakage. What are the
disadvantages of the double cylinder? The first is that the shell
bucket with a double cylinder is heavier, and the synchronization
of grabbing is worse. The overall weight of a single cylinder is
lower, and the synchronization is better, the grabbing efficiency
is higher, but the failure rate is higher.
Q:What is the material of the telescopic arm?
A: The arm tube is made of BS900E, and other parts are made of
Q3558, which is lighter and more durable. We use a thickness of
6mm.
