Product Presentation of Excavator Extension Arm
The long arm of the excavator is made of Q355B steel with good
strength and rigidity. The shaft sleeve of the lengthened arm is
generally made of 45 # steel, with 40Cr bushing inside, together
with the lubricating effect of butter, it reduces the shear force
produced when the shaft and the sleeve rotate frequently, thus, the
service life of the shaft sleeve is increased. In the construction
of water conservancy and hydropower projects, it is also a major
project that often uses excavator long arm, which can be excavated
according to the required depth. In water conservancy and
hydropower engineering, the long arm of excavator is called the
king of dredging in engineering. It can be seen that its excavation
capacity is very good and its dredging capacity is stronger. And in
the use of hydraulic engineering can also be lengthened according
to the specific depth of the modified arm length.

Advantages of Zhonghe Long Boom Excavator
1. Less maintenance
Using high quality materials, such as Q355B as default, Q690D
optional, Niningbo connectors, seamless precision pipelines,
graphite alloy copper sleeve, and strong but light bucket cylinder.
2. Strong and sturdy
Built-in reinforcing ribs. Professional welding skills towards the
different bearing positions. Groove preparation(45° edge-mining)
before welding.
3. Tolerance within 5-10um
Hole drilling tolerance is within 5-10um, ensure accuracy.
4. 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.
5. High work efficiency and saving fuel
Lighter while taking into account the quality, not only ensures
work efficiency but also saves fuel.
6. Fillet weld testing
We can determine the quality of a fillet weld joint by performing
NDT and mechanical testing. Macro examinations and fillet fracture
tests give a good view of the profile, fusion and penetration, and
reveal whether there are any imperfections, such as porosity or
inclusions, in the weld. These tests are used to test the welder’s
ability to weld a fillet weld.
