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.
Technical staff:
Our chief engineers have experience customizing different kinds of
long stick excavators over 10 years.
We have customized more than 100 heavy-duty long excavator booms for powerful excavators (crawler or floating platform), like
