Telescopic Boom/Sliding Arm Specifications
The sliding arm serves to excavate deep wells, foundation pits, tunnels, and sewage pipelines, among other municipal projects.
Since our inception in 2018, we have gained over 6 years of industry experience. Our production line engineers have more than 10 years of expertise in crafting and customizing long arms for various excavator models.
This product is suited for all excavator types, and we provide OEM services as needed.
We implement an advanced manufacturing process that complies with global technological standards.
We hold all installation measurements for most excavators, allowing us to customize this long arm specifically for your needs.
Prior to welding, a large milling machine is used to mill the edges of the steel plate (taper processing), enabling deeper penetration of the weld, thus enhancing structural performance. Reinforcement plates are installed inside for added strength.
Should you need it, we can incorporate additional pipes for specific applications.
The arm cylinder of the long boom allows you to use your original arm cylinder to cut costs; if you need a new one, we can arrange that for you.
Certain components can be fortified with thicker plates or by overlapping additional plates for heavy-duty usage.
Our welding process uses shielded gas welding, with a shielding gas composition of 80% argon and 20% carbon dioxide, recognized as the top standard.
EXCAVATORS WITH A TELESCOPIC ARM
(UPPER ARM SLIDING TYPE)
1. Thanks to the hydraulic sliding system in this model, the arm contracts and expands (‘telescopes’) speedily, providing high working efficiency.
2. Sliding mechanisms using rollers on the slide surfaces makes adjustment easy and prevents vertical and horizontal vibrations of the arm, which in turn minimises the wear which shortens arm life.
3. With the arm extended, the excavator can dig to the same depth as machines three (3) classes higher, so this becomes a useful attachment for restricted job sites where a wide working range is needed.

What is the purpose of beveling the long arm/tunnel 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).

FAQ(Some frequently asked questions):
Q1: Are you a manufacturer?
A1: Yes, Zhonghe Machinery manufactures various excavator attachments, including demolition arms and different types of buckets. We focus on a blend of high-quality steel and reasonable prices for success.
Q2: How long is the sliding arm for a conventional 20-ton excavator machine?
A2: Our 9-meter sliding arm allows for digging more than 8 meters or close to 9 meters without lowering the arm.
Q3: What length does the 10-meter sliding arm in our product price list refer to?
A3: The 10-meter designation represents the maximum digging depth of over 10 meters, not the arm's length.
Q4: What are the advantages of our sliding arm?
A4: First, our double limit design reduces vibrations. Second, we use a wear-resistant block design for better maintenance and longer service life. Third, it utilizes more original accessories, which saves costs. Finally, we have double-layer oil seals on our cylinders to lower failure rates.
