Product Presentation of Excavator Extension Arm
The extended arm is generally made of Q345B steel, which has good strength and rigidity. The bushing is generally made of 45#+20# steel, inset with 40Cr bushing and lubricated butter, which greatly reduces the shear force generated by the frequent rotation of the shaft and bushing, thus increasing the service life of the bushing. The lengthened arm is generally a box-type structure, that is, it is composed of two upper and lower cover plates and two left and right wall panels. The internal buffer bars must be welded, and the buffer bars must be opened with elliptical holes so that the stress generated by the lengthened arm during welding and working can be better released, and the damage to the lengthened arm can be avoided.

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. Mechanical tests
Various mechanical tests of boom welded samples. Also known as destructive tests, they can be used for design purposes and to determine whether variables used to produce welded joints are acceptable. Mechanical testing allows us to determine material properties including yield strength, ultimate tensile strength, ductility, notch/impact toughness, fracture toughness, and hardness.
