For general engineering construction machinery, only training certificate, construction operation certificate and skill grade certificate are needed.
Special equipment catalogue
Since 20 12, construction machinery is no longer listed as a special equipment catalogue (except for a few models such as tower cranes, construction lifts and cranes).
Do not belong to special equipment
Most types of construction machinery, such as excavators and loaders, are no longer special equipment and do not involve special operations, so they are no longer special operation certificates.
