Introduction of excavator boom and stick production process.
Long reach excavators work in the harshest conditions you can imagine. Our ultimate goal is to extend the dependable service life of the product. All long reach fronts are shot blasted to ensure the steel surface is thoroughly clean and free from contaminants and rust. In addition, this process presents the steel with a textured surface that provides excellent adhesion for the prime coat of paint.
