Heavy-Duty Machines to Move the Earth Construction vehicles are designed for building structures such as buildings, bridges, and roads. This often involves moving large quantities of soil or rock and heavy building materials. Without construction vehicles, structures such as the Hoover Dam and the Empire State Building might not have ever been built. Each construction vehicle looks and functions differently, because they are built to accomplish specific tasks.

CHECK IT OUT THE SCREW Concrete and Cement On this page, you can learn about two of the most important building materials that are manipulated by heavy construction equipment. Inside the drum of a concrete tra nsport truck is a spiral blade that when rotated on e way, pushes the liquid concre te deeper into th e drum. But, when the drum is rotated in the op po site direction, it push es the concrete ou t of the drum. The blade acts lik e an Archimedes ’ screw.

DeepLifters Space CHECK IT OUT Levers and Pulleys Cranes are often equipped with pulleys and cables that are used to lift and lower materials and move them horizontally. The pulleys in a crane minimize the amount of work needed to lift the object off the ground. In order to lift large loads, a crane must also have a counter balancing load, so that the crane does not tip over. The load and balancing load act as a lever.

B motor motor 58 C A A road grader is a large construction vehicle with a long blade that is used to create surfaces with a specified slope during a process called grading. Grading is important for the foundations of buildings, railroads, and landscapes. Grading allows civil engineers to direct the way that water, from rain or irrigation, flows off a piece of land. The grader’s purpose is to refine the grading.
