First, where do you work? If it is a tower crane in a coal mine, you should go to the Municipal Safety Supervision Bureau for an operation certificate.
If you are working on a construction site, go to the Construction Engineering Safety Supervision Station of the Municipal Housing and Construction Bureau for consultation (he will explain the relevant training places to you during the consultation). If it is training, the relevant conditions are required: (1) at least 18 years old, meeting the age requirements stipulated by relevant types of work; (2) Having passed the physical examination in the hospital, and having no diseases or physical defects that prevent them from engaging in corresponding special operations; (3) Junior high school education or above; (four) other conditions that meet the needs of the corresponding special operations.
The general training period is one week, and it takes about two months to issue certificates after passing the training.
