What are the lifting machinery in the special equipment catalog
Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipes, elevators, hoisting machinery, passenger ropeways, large amusement facilities and special motor vehicles in the field (factory) that involve life safety and greater danger . Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects. Its scope is specified as a lift with a rated lifting capacity greater than or equal to 0.5t; a rated lifting capacity greater than or equal to 3t (or rated lifting torque) Tower cranes greater than or equal to 40t·m, or loading and unloading bridges with a productivity greater than or equal to 300t/h) and cranes with a lifting height greater than or equal to 2m; mechanical parking equipment with a number of floors greater than or equal to 2 floors.
In the above paragraph, we see that cranes with a rated lifting capacity greater than or equal to 3t and a lifting height greater than or equal to 2m are all special equipment. This is why we say that cranes of more than 3 tons are required to be inspected.
Cranes above 3 tons are special equipment
Among the cranes, there are two common types of cranes: bridge cranes and gantry cranes:
1. Bridge crane
General purpose bridge crane
Explosion-proof bridge crane
Insulated bridge crane
metallurgical bridge crane
Electric single beam crane
Electric hoist bridge crane
2. Gantry crane
General gantry crane
Explosion-proof gantry crane
Rail-mounted container gantry crane
Rubber-tyred container gantry crane
Quayside container crane
Shipbuilding gantry crane
Electric hoist gantry crane
Loading bridge
Erecting machine
Other cranes belonging to special equipment include:
1. Tower crane
Ordinary tower crane
Power station tower crane
2. Mobile crane

Crawler crane
Container reach stacking crane
Railway crane
3. Portal crane
Portal crane
Stationary crane
4. Lift
Construction lifts
Simple lift
5. Cable crane
6. Mast crane
7. Mechanical parking equipment
For the safe production of enterprises, the state stipulates that special equipment needs to be submitted for inspection and filing, and relevant units must strictly abide by the national regulations.
