Plus the long arm excavator production is generally used 3D computer-aided design system to do stress analysis and motion simulation, in addition to proficiency in processing equipment, staff skills and practical application of knowledge, experience, and material selection, production process and other aspects of the long arm of the excavator structural strength, performance and quality has a major influence. Technology and processes in general: computer design --- CNC Cutting (manganese plate) --- bending machine bending stereotypes (horse parts) --- professional mechanic welding boring boring ---- ---- large extended arm mount and piping installation ---- ---- bucket cylinder installed anti-stress test product blaster ----- ---- ---- hot spraying thoroughly examined before delivery ---- qualified factory . Plus the long arm excavator into a two-stage, three-stage, four-part, two-stage mainly applied to earth and sand, concrete and other building transportation, highway slope repair and dredging river dredging and building foundation, rivers, deep groove, etc. Earthwork excavation work and the like; three-stage, four-section is mainly applied to the dismantling of high-rise buildings and other operations, such as building body of the company's standard size excavator arm, strengthen the size of arm, plus the long arm of the two-stage, three-stage or multi-stage demolition arm, is widely used in terminals, subway construction, river clean-up, house demolition and other construction industry, the production of standard excavator bucket, rock bucket, shell type bucket, cleaning bucket, tilt bucket and a variety of special-bucket, grasping forceps device, grasping wood, ripper, cylinder, quick-change connectors and other construction machinery spare parts manufacturers.
