In the very distant past, people used different methods to pave the roads, and the roads were usually made of dirt or cobblestones in the past. Nowadays, various materials are used to smooth the roads, the most famous of which is asphalt.
During the process of road construction, various machines and tools are used. We pay.
There are many different industrial machines with different and different uses, each of which is suitable for building a specific part of the road construction project. These machines have various spare parts, such as undercarriage and engine parts, which must be replaced when needed so that there is no disruption in the service of road construction machines.
Bulldozer and tractor
Tractors are automatic and standard gear type machines that get their power from diesel engines that are usually turbocharged. The control of tractors is in the form of automatic gear and hydraulic control, which generally exist in two types of chain wheels and rubber wheels. It can be safely said that tractors and bulldozers are among the most important construction and road construction machines. The main and primary job of the tractor is to push loads backwards or forwards, but in general, they have many uses and many uses, which are mentioned below.
Mechanical shovels
Another important road construction machinery is mechanical excavators, which is essential to know about road construction machinery and their applications. Mechanical excavators consist of the following three basic parts:
Carriage or chassis: There are two types of chassis: a chain wheel chassis with a speed of 50 km per hour and a rubber wheel chassis with a speed of 80 km per hour. br> The revolving chamber part on the carriage
The extension part in front of the car
Mechanical excavators are among the first modern construction machines that are usually used in earthworks and digging. Mechanical excavators in the powerful type are able to excavate in all kinds of soils except rocks. Excavators are available in four types: reverse bucket excavator, cable system excavator, crawler excavator and crane, each model has different applications and these applications can be seen below:
Simple digging
Excavation
Carrying bodies
Excavating
Digging chips
Crane
The crane consists of a steering room, a crane heart and a long mesh beam. A crane is usually used to lift objects and loads and move them from place to place. People usually use it for other purposes by connecting different devices to the end of the crane. There are two types of cranes, mechanical and hydraulic, and nowadays there are usually more hydraulic types.
Script
The third machine in familiarizing with the types of road construction machinery and their applications is the scraper. This machine is capable of transporting, loading and unloading earthen materials in long and medium distances. The scraper is made of three main parts: the loading part, the loading front wall, and the loading rear wall. Scrapers are usually used in lands that are free of large stones, and these machines are used for operations and projects where the use of bulldozers is not economical. Scrapers are available in two categories, motorized and non-motorized, and nowadays the motorized type is used more.
Loader
The fourth machine in familiarizing with road construction machines and their uses are loaders, which are the most useful machines for construction works. Due to its great flexibility in performance and changing the cup, it is able to do many things. Loaders are made in different sizes. Loaders have many applications and uses, some of these applications include the following options in getting to know the types of road construction machinery and their use. dredging
removing obstacles
Road roller
Road construction roller is used for road and track construction operations and the application of this machine is in compacting road construction materials. One of the most basic and major reasons for using road construction rollers is to improve soil characteristics, which is the most important to achieve the density of soil layers.
Rollers exist in different types, which are classified based on their structure and capabilities. The types of rollers available can be seen below.
