Construction machinery refers to the heavy equipment and tools that are typically used on construction sites to perform a variety of tasks. These machines are designed to make construction tasks faster, easier, and more efficient. Some common examples of construction machinery include:

1. Excavators: used for digging, grading, and leveling the ground
2. Bulldozers: used for pushing and leveling large amounts of earth and other materials
3. Backhoes: similar to excavators, but with a smaller digging bucket and the ability to dig in tighter spaces
4. Cranes: used for lifting and moving heavy loads
5. Concrete mixers: used for mixing and pouring concrete
6. Pavers: used for laying asphalt and other surfaces on roadways
7. Compactors: used for compacting soil and other materials
8. Dump trucks: used for hauling and transporting materials to and from the construction site
9. Loaders: used for moving and loading materials, such as dirt, sand, gravel, and debris
10. Graders: used for leveling and shaping land surfaces

These are common examples, and many other machines are used in construction such as scrapers, rollers, asphalt pavers, skid steer loaders, telehandlers and much more. Depending on the nature of the construction work different machines can be used.
