The certificate of competency based on the industry standard of construction machinery and equipment is universal for the operation level. At present, the job training of construction machinery carried out by Jianji mainly focuses on three categories: "equipment operation", "installation and disassembly" and "maintenance". The quality supervision department is responsible for the supervision function in the field of manufacturing, and no longer handles the operation certificate of construction machinery in the construction site. Belonging to the post type of special equipment and special operations, trainees should consciously accept the government's special equipment and special operations safety training and obtain the qualification certificate of special operations after obtaining the qualification certificate of post ability training and the operation certificate of construction operation.
