Excavator Boom Cost

General Information

Excavator boom cost many idea and thoughts of the producers. The integral bending boom is the main form of the boom of backhoe excavator. The downward bending form is mainly used to achieve a large excavator depth. The boom consists of upper and lower straight sections and three sections bent in the middle. The boom is welded as a whole. In terms of structure, the integral bending boom is a left-right symmetrical closed medium empty box welded structure. Generally, the hinged parts of the upper and lower ends are steel castings, and the three sections in the middle are high-strength and high-quality steel plates.

Stiffened plates are generally welded inside the excavator boom, especially at the hinge with the boom oil cylinder, to further strengthen the local strength and ensure that the boom has high bending and torsional strength as a whole.

Due to the bending and processing technology, the bending boom has inevitable welding deformation and stress concentration at the bending, so the processing technology and strength are very important. In the production process, ultrasonic flaw detection is usually used, and there isn't supposed to be any excavator boom problems, for instance, the excavator rock boom without any small cracks, which will be considered as qualified products.
