Product Presentation of Excavator Boom
The boom of the excavator is made of Q355B
steel, which has good strength and rigidity. The extension arm
sleeve is generally made of 45# steel, lined with 40Cr bushing.
Coupled with the lubrication of butter, the shear force generated
by the frequent rotation of the shaft and the sleeve is reduced,
thereby improving the service life of the sleeve. It is equipped
with an extension arm between the body support and the working arm.
The extended arm is connected and supported by the oil cylinder,
which increases the work of the extended arm oil cylinder and the
bucket oil cylinder. There are corresponding control systems inside
and outside the cockpit, and one set of oil cylinders is matched
with one set of oil cylinders. Especially suitable for mines,
docks, storage, flood control and emergency rescue and special
occasions. It is a major breakthrough transformation of mining
machinery and has great practical value.

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.
