Tractors and bulldozers:
Tractors are the most important road construction and construction machines, which have many applications. The primary purpose of the tractor is to push or pull all kinds of loads. All kinds of mechanical equipment can be installed on the tractor. In addition to tractors, they also use other things such as pulling scrapers, wagons, etc.
Types of tractors:
A- Chain wheel tractors
B- Rubber wheel tractor
2. Mechanical frames
Excavators are one of the first modern construction machines that are used in earthworks. Excavators are mainly used for excavating in the soil and loading it with a truck or trolley or conveyor belt. Its powerful types are capable of excavating in all types of soil except rocks and stones without initial destruction.
Mechanical excavators consist of three basic parts: the carriage - the rotating chamber part on the carriage and the additional part in front of the car.
Types of mechanical billers:
A- Excavator with reverse cup
B- Excavator with cable system
C- Excavator (dragline)
D- Crane
3. Script
A scraper is a machine that carries out the loading, transporting and unloading of soil materials in medium and long distances alone.
Types of Scripts:
1. Two-axle single engine
2. Three-axle
3. Two-wheel drive
4. Twin-engine scrapers (TANDEM-POWERED)
5. Elevating scrapers
6. Pressure - Stretching (PUSH - PULL)
4. Lodges
Without exaggeration, the loader is the most useful machine for construction and construction work. This machine is made in different industries because of its great performance and flexibility, and it can do many jobs by changing the cup.
Loader Types:
A- Rubber wheel loader
B- Chain wheel loaders
C- Backhoe loader
5. Games
Although tools such as scrapers, conveyor belts, and trains are used to transport earth materials, trucks are the most common means of transporting earth materials. Due to the high speed on the roads, these transporters reduce the cost of transporting materials relatively low. They are very flexible because the number of them that are used in a project can be increased or decreased so that the required capacity can be adjusted.
6. Tarler
Different machines are used for leveling the land and removing elevations and elevations, but the most important tool for the operation of adjusting the slope and leveling the embankments and excavations and bringing the soil surface to the desired level (project line) is done by grader. The operation of adjusting the slope is one of the most difficult tasks All drivers of road construction machines are of the opinion that working with a grader is better than other machines, and a driver who has skills in using a grader can easily control and guide the rest of these machines.
7. Gracers (Compactors)
8. Garder
The grader is used for adjusting the slope, shaping the slopes, leveling the range of embankments and excavations, digging and mixing and spreading the mixture of soil and bituminous materials. These machines are used in the construction of roads and other construction operations. /p>
