Description of the roller and excavator.


Road roller is classified as construction machinery. using it, it is possible to compact the soil properly, and this is the most important thing it does. It is irreplaceable in the case of work during the compaction of pavement mass during road construction, and also during earthworks. Depending on the roller model, and more precisely on its severity, it can act up to four meters deep in relation to the ground. Work with this device is carried out perfectly and in accordance with the safety rules.

We can distinguish battles due to various parameters, including:

Due to the way they affect the substrate, we distinguish.

  • Vibrating - affects the surface in a dynamic and static way. At the same time, it is able to withstand vibrations up to 50 hertz, and the depth it exerts on the ground reaches up to four meters.
  • Stable - it acts only on the surface with its own weight, which results in a slight depth. It is usually used for finishing works.

It is also possible to divide the shafts according to their elasticity (steel, rubber) and shape (smooth, disc, spiked, mesh, compactors).

Construction machinery - excavators, rollers ..Excavator

The excavator is one of the most important machines in construction and is indispensable in every construction industry. There are many types of excavators on the market, each with different specifications and applications. It is most often used for earthworks, among others, the separation of spoil and loading it into landfills or transport vehicles. On the one hand, each type and application of an excavator differs, but they have common points. Namely, the chassis, which is the load-bearing unit for the body, and the device on which the operator's cabin, engine, and controls are mounted.

  • Working in an intermittent cycle.
  • Continuous operation.

Application and types of excavators depending on the equipment:

  • undershot,
  • enterprising,
  • gripper,
  • mini excavator,

Excavators by type of undercarriage:

  • placed on a two-wheeled trailer,
  • placed on another means of transport,
  • rolling,
  • on a wheeled chassis,
  • on a tracked chassis.

Methods of control and drive of excavators:

  • electric control,
  • hydraulic control,
  • pneumatic control,
  • mechanical control,
  • powered by an electric motor,
  • powered by an internal combustion engine,
  • driven by an internal combustion engine.
