Loader
In principle, it can be said that loaders are placed in one of the categories of giant road construction machines, which are widely used in construction works to carry mass of materials (such as soil and stone), loading trucks, digging, digging and Sometimes leveling (as a bulldozer) is used. Unlike scrapers, which are used for loading and carrying at the same time, loaders should always be used together with transfer machines such as trucks.
Beckho Loader
A backhoe loader consists of a loader in the front and an excavator in the back. The size of the backhoe loader is smaller than the loader and excavator. And it is usually used for smaller workloads. The backhoe loader is used for shallow digging, creating small and medium channels for piping and moving and transporting soil. The types of backhoe according to the operational conditions are as follows:
🔸Fully rotating
🔸Fixed
🔸Mechanical sliding
🔸Hydraulic sliding

Excavator
Various types of excavators are used for digging in soft and hard soils, soft stones and non-stone materials. It is used for digging channels for placing pipes and cables of electricity, telephone, water and sewage departments and large ponds and its special type for mines. Excavators can dig all types of soil except rocks. The rocks must be first destroyed by devices such as rippers or hydraulic hammers and then removed by shovels.
Bulldozer
Roller
Compactors, which are also called rollers, are widely used in road construction to compact the final surface and soil materials. Different types of rollers are available for different compaction jobs. For the compaction of granular soil such as sand, crushed stone, smooth metal wheel rollers are effective.
Grader
Grader is another type of road construction machinery that is primarily used for leveling or finishing earthworks. This machine is widely used in the construction of dirt roads, spreading loose materials and shaping the subsurface. The grader is also useful for slope correction and sand mixing.
