It is one of the most necessary construction machines because of its leveling role and its power. Mounted on tracks or on tires, it is a powerful and massive tractor with a robust front blade in front of which nothing can resist. When the blade is lowered, it pushes materials by scraping the ground to level the ground. But in high position, it allows the transport of materials. In addition, the bulldozer is also used to demolish, to deforest, to strip topsoil or to push scrapers.
It is the most representative machine of major earthworks. It allows to extract and transport loose materials at medium distance. Working like an extraction planer, it has a loading box with a drawer that penetrates the ground and level it. Most scraper models require when loading assistance of a push bulldozer. The latter provides the energy required to extract the material. And it should be noted that the scrapers allow to obtain better returns than the excavators loading dumpers.On small sites, small excavators called mini excavators or mid excavators are used.
It is a machine which one cannot generally do without on an earthwork site for its versatility. Also called hydraulic mechanic shovel, it is easily recognizable by its long arm secured to a turret that can rotate 360 °, all mounted on a chassis with tracks or tires. As well suited for digging holes as for clearing, it is used to move heavy materials. In addition, it can prove itself on a demolition site. Likewise, sanitation work (trench excavations) or drilling are areas of predilection for this machine. On small sites, small excavators called mini excavators or mid excavators are used.
The loader is a very popular earthmoving machine. Moving on tires or tracks with great pushing power, it is equipped at the front with a bucket which allows to move a large amount of material. It is used for clearing or backfilling, handling (loading, unloading), demolition, road construction, landscaping and others. Coupled with an excavator, it becomes a backhoe loader.
