Product Description-------Excavator Telescopic Boom
What is an excavator telescopic arm?
The telescopic arm of an excavator is a flexible tool that increases its operational scope. By extending and retracting, it allows for effective digging, lifting, and other tasks across various construction and demolition applications.
What are your advantages?
Advantages of telescopic arms:
1. Our telescopic boom consists of three sections crafted from
BS900E and Q355B, balancing lightness and durability.
2. It features a solid 6mm thickness for added strength.
The use of nylon sliders and steel pulleys, along with centralized
lubrication, enhances performance.
3. An external hose pulley on the bucket cylinder makes hose
repairs and replacements simpler.
4. The design effectively separates hoses from the main rope,
reducing friction and wear.
5. With a dual-rope mechanism, the arm will not extend if the primary rope breaks, ensuring safety.

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:
- Construction in Limited Areas: The telescopic arm is perfect for construction tasks in areas with limited space to maneuver.
- Deep Digging Projects: It excels in deep digging projects, such as basements and underground utilities.
- Demolition in Urban Settings: The arm allows for efficient demolition in densely populated areas without excessive repositioning.
- Tight Quarters Excavation: It is well-suited for excavation in tight quarters where traditional arms may struggle.
- Utility Installation: The telescopic arm can reach areas that are challenging to access for utility installation.
- Repair Work on Elevated Structures: It is effective for maintenance and repair work on elevated structures like bridges.
- Heavy Lifting Tasks: The arm’s reach allows it to lift heavy materials in areas that are difficult to access.
- Environmental Restoration: It can be used in environmental restoration projects where precise digging is necessary in confined 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.
