Construction vehicles are specialized machinery and equipment used in the construction industry for various tasks such as excavation, grading, transportation, and material handling. Some common types of construction vehicles include:

1. Excavators: large machines with a long arm and a scoop or claw on the end, used for digging and moving dirt and other materials.
2. Bulldozers: heavy machinery with a large blade on the front, used for pushing and leveling dirt and other materials.
3. Backhoes: smaller version of excavators, with a digging scoop on one end and a backhoe on the other, often used for digging trenches and foundations.
4. Loaders: vehicles with a large scoop or bucket on the front, used for moving and loading materials such as dirt, gravel, and debris.
5. Graders: heavy machinery with a long blade on the front, used for leveling and smoothing surfaces such as roads and parking lots.
6. Cranes: large machines with a tall tower and a long arm, used for lifting and moving heavy loads such as steel beams and precast concrete.
7. Rollers: heavy machinery with a large drum on the front, used for compacting soil, asphalt, and other materials.
8. Pavers: equipment used to lay and smooth asphalt or concrete, on roads and other surfaces.
9. Dump Trucks: vehicles used for transporting loose materials such as dirt, gravel, and debris to and from construction sites.
   These construction vehicles are essential for the efficient and effective completion of construction projects. They are operated by skilled operators and are designed to handle the heavy loads and demanding conditions of the construction industry.
