Construction machinery, learn about it

Today, let's talk about the road construction machinery? Do you know what large machines are available for road construction? Now let's have a look.

1. Loader

Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used to shovel soil, sand, lime, coal and other bulk materials, and also can do light shovel excavation for ore, hard soil and so on. In the construction of roads, especially in high-grade highways, loaders are used for filling and excavation of subgrade works, aggregate and loading of asphalt mixtures and cement concrete yards. In addition, it can also carry out operations such as pushing and transporting soil, scraping the ground and towing other machinery.

2. Shovel excavator

The shovel action form of the shovel excavator. It is characterized by "moving forward and forcibly cutting soil". The front shovel has a large excavation force and can excavate the soil of the front shovel above the parking surface. It is suitable for excavating dry foundation pits with a height of more than 2m, but an up and down ramp must be set. The bucket of the front shovel is larger than that of the backhoe excavator of the same equivalent. It can excavate class I to class III soil with a water content of no more than 27%, complete the whole excavation and transportation operation with the dump truck, and excavate large dry foundation pits and mounds.

3. Loader

Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used to shovel soil, sand, lime, coal and other bulk materials, and also can do light shovel excavation for ore, hard soil and so on. In the construction of roads, especially in high-grade highways, loaders are used for filling and excavation of subgrade works, aggregate and loading of asphalt mixtures and cement concrete yards. In addition, it can also carry out operations such as pushing and transporting soil, scraping the ground and towing other machinery.

4. Backhoe excavator

Backhoe excavator is one of our most common excavation equipment. It is mainly used for the excavation of foundation pits (grooves) or pipe trenches, independent foundation pits and slopes below the working face; Straight line and curve excavation, excavation with a certain angle, ultra deep ditch excavation and ditch slope excavation, etc.

5. Roller

Road rollers belong to the category of road equipment in construction machinery, and are widely used in the filling and compaction of large-scale projects such as high-grade highways, railways, airport runways, dams, stadiums, etc. they can roll sandy, semi cohesive and cohesive soils, subgrade stabilized soils and asphalt concrete pavement layers. The roller is applicable to various compaction operations by the gravity of the machine itself, so that the compacted layer will be permanently deformed and compacted. Road rollers are divided into steel wheel type and tire type.

6. Asphalt concrete paver

A machine that evenly paves the asphalt mixture on the road base, and performs preliminary compaction and leveling. There are two types: crawler type and tire type. It is composed of traction, paving, vibrating and ironing. The former includes frame, power device, walking device, hopper, material door, scraper conveyor, spiral paver and cab. The latter includes traction arm, vibrating mechanism and ironing device (composed of screed, thickness adjuster, camber adjuster and heating device).

That's all for today's road machinery. How many of these machines do you know.
