Custom Long Reach Excavator Reach, OEM ODM 8-30 Meters Extended
Boom Arm for CAT Hitachi 6-120 ton Excavator Long Arms
The long-reach Excavator Arms provide numerous advantages compared
to standard excavator arms. The inclusion of the Zhonghe Excavator
Long Boom allows excavators to achieve greater depths, heights, and
distances, thereby offering enhanced flexibility and versatility.
Moreover, the long arm of the excavator enables more precise
operations in confined spaces, thanks to its smaller digging radius
compared to larger excavators.
The Zhonghe Long Reach upgrade package significantly enhances the
excavator's capabilities, resulting in improved efficiency and
effectiveness across a wide range of projects. These projects
include deep foundation excavation, industrial demolition,
precision dredging at greater depths or heights, large-scale
excavation projects, barge unloading, tank cleaning, municipal
engineering, railway construction, river dredging, river cleaning,
and any task where standard boom and stick assemblies are
impractical or inefficient.

For Materials:
The primary material of the boom and arm is Shaogang Q355B and
Q690D, the Hydraulic tubes are national standard precision
seamless, and the pins are 40MuCr, The high-pressure hoses consist
of four layers of steel rings, while the grease pipe is a
single-layer hose. The bushing, driven into the base of the boom,
is made of graphite alloy copper sleeve.

Our company Kaiping Zhonghe Machinery Manufacturing Co., LTD is
specializing in manufacturing various types of bucket and other
related spare parts. We have different kinds of attachments, such
as: buckets, ripper, grapple, quick coupler, hydraulic crusher,
boom and arm,bulldozer shovel, bulldozer ripper, loader bucket,
loader grapple etc.
Our production process:
1. The extended arm plate is precision-cut using a plasma cutting
needle to ensure accuracy.
2. Before welding, the plate edges are milled (tapered) using a
large edge milling machine. This allows for deep penetration of the
weld into the steel plate, enhancing the overall performance of the
structure.
3. Flaw detection tests are conducted using specialized instruments
after welding.
4. After welding, a double-sided large-scale floor-standing boring
machine is employed for precision boring. This ensures the
long-reach arm concentricity during operation and extends its
service life.
5. Following grinding, a sandblasting process is carried out to
achieve a specific level of roughness and cleanliness on the long
arms. This enhances their strength, hardness, and corrosion
resistance.
Usually use 40GP container to load product !
