Product Presentation of Excavator Boom
The boom of the excavator is made of Q355B steel, which has good strength and stiffness. The extension arm sleeve is generally made of 45 # steel and lined with 40Cr bushing. In addition, the grease lubrication reduces the shear force generated by the frequent rotation of the shaft and sleeve, thus improving the service life of the sleeve. An extension arm is arranged between the main body support and the working arm. The boom is connected and supported by the oil cylinder, which increases the work of the boom cylinder and bucket oil cylinder. There are corresponding control systems inside and outside the cabin, and one set of oil cylinders matches one set of oil cylinders. It is especially suitable for mines, docks, warehouses, flood prevention and emergency rescue and special occasions. This is a major breakthrough in the transformation of mining machinery and has great practical value.

Advantages of Zhonghe Excavator Long Arm
1. Less maintenance
High quality materials are used, such as Q355B (default), Q690D (optional), Ningbo connector, seamless precision pipe, graphite alloy copper sleeve and solid but lightweight bucket cylinder.
2. Firm and durable
Built in stiffeners. Professional welding skills for different bearing positions. Groove preparation before welding (45 ° edge mining).
3. Tolerance is within 5-10um
The drilling tolerance is within 5-10um to ensure accuracy.
4. Deeper and higher
The maximum operating range and the maximum digging height are greater because the angle between the boom and the boom can reach 163 degrees.
5. High working efficiency and fuel saving
It is lighter while considering the mass, which not only ensures work efficiency but also saves fuel.
6. Fillet weld test
We can determine the quality of fillet welds by performing non-destructive testing and mechanical testing. Macro inspection and fillet weld fracture tests can well observe the weld contour, fusion, and penetration, and reveal whether there are any defects in the weld, such as pores or inclusions. These tests are used to test the welder's ability to weld fillet welds.
