What are the classification of construction machinery?

First, engineering machinery is usually classified:

Lifting machinery, transport machinery, earthmoving machinery, piling machinery, stone mining and processing machinery, reinforced concrete machinery and equipment, decoration machinery, pavement machinery, line machinery, tunnel construction machinery, bridge construction machinery, etc.

1. Lifting machinery:

Used for heavy lifting and installation. There are generally four parts: lifting, turning, changing amplitude, and walking. Lifting is the main part. Simple, boom rotation and bridge type three. The main models include tower cranes, wheeled cranes, and crawler cranes. There are also not fully equipped with the above four parts, such as mast cranes, cable cranes, elevators, winches and so on.

2. Transportation machinery:

It is used for the transportation and handling of materials, including continuous conveying machinery, handling vehicles and loading and unloading machinery. 1 The continuous conveying machine can be continuously operated with high productivity. It is suitable for conveying materials along a certain route. The main types of machines include belt conveyors, screw conveyors, vibratory conveyors, bucket elevators, and pneumatic conveying devices. 2 handling vehicles: flexible and versatile. The main models are dump trucks, dump trucks and forklifts. 3 loading and unloading machinery: used for continuous or intermittent loading and unloading of materials.

3. Earthmoving machinery:

Used for excavation, transportation, filling, compaction and leveling of earthwork. Digging machinery, shovel transportation machinery, compaction machinery and peacemaking machinery.

4. Pile Machinery:

It is used in basic engineering and various piles are installed in the ground. There are pile drivers, vibratory pile drivers, pile drivers and cast-in-place pile drills.

5. Reinforced concrete machinery:

For concrete ingredients, mixing, conveying, pouring, vibrating and rebar processing.

The main equipments and machinery include concrete mixing plant, self-falling and forced concrete mixers, concrete mixer trucks, concrete pumps, concrete vibrators, cold drawing, straightening, shearing, bending, welding and other machinery. Prestressed steel tension and other mechanical equipment.

6. Stone mining and processing machinery:

For stone mining and stone processing. Stone mining machinery has wind picks, rock drills and so on.

Stone processing machinery includes various stone crushers and screening machines.

7. Decoration Machinery:

For the decoration of the building surface and processing. There are plaster mixers, mortar transfer pumps, spray guns, etc. for plastering and painting operations, floor polishers for floor processing, and coating sprayers and various electric and pneumatic hand-held machines.

8. Road Machinery:

It is used for paving, compaction, smoothing and kerfing of pavement, airport pavement and plaza floor surface.

There are gravel pavers for bituminous pavement construction, asphalt sprayers, asphalt concrete mixing equipment, asphalt concrete pavers, cement concrete pavement paving machinery for the construction of cement concrete pavements, slitting and seaming machines, and also pavement materials. Preparation, storage, transportation, and pavement maintenance machinery.

9. Line Machinery:

Used for laying railway rails and rails.

The main models include paving machines, track-laying machines, and railway maintenance maintenance machinery (see track laying).

10. Bridge Machinery and Tunnel Machinery:

Used for bridge construction and tunnel construction. There are railway bridges, shields, tunnel boring machines, etc.
