CE Certification Practical 6-55 Ton Long Reach Excavator Booms For
Hitachi Komatsu Sany Pc200 Cat320
Excavator long reach boom arm has a longer working distance, which
reduces the displacement of the machine and increases the work
efficience at the same time.
All of them would be connected together, so that would be more
convenient for your installation.
Advantages:
- Good panel material
- Full and smooth welding
- High quality connecters
- 24-hours online service
- Provide simulation diagrams
Notice: arm cylinder and counterweight, excavator are not included.

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 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.
Precision:
1. Tolerance within 5-10um
Hole drilling tolerance is within 5-10um, ensure accuracy.
2. Reach deeper and higher
The max work range and the max digging height are larger as the
angle of the boom and arm can reach 163 degrees.
3. High work efficiency and saving fuel
Lighter while taking into account the quality, not only ensures
work efficiency but also saves fuel.
Usually use 40GP container to load product !
