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.

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.

FAQ of excavator long arm

Q1: Why not have boom and stick cylinders in the plan?
