Resumen

Los compactadores, también llamados rodillos, son máquinas de equipo pesado utilizadas para la compactación del suelo. La compactación tiene lugar en casi todos los proyectos de construcción para tareas como la densificación del relleno. La compactación aumenta la densidad del suelo debido a la expulsión de aire por medios mecánicos. Los dos tipos de fuerzas de compactación incluyen la fuerza estática, en la que el peso propio de la máquina aplica una presión descendente sobre la superficie del suelo, y las fuerzas vibratorias, en las que los compactadores crean una fuerza descendente sobre la superficie.

Los compactadores de tierra más comunes son los compactadores de tambor liso, los compactadores de pata de cabra y los compactadores de pata de oveja.

Preguntas frecuentes

  • Used compactors cost anywhere from $10,000 to $150,000

  • The best compactor manufacturers include Jamieson, Ludman, Köppern, Dynapac, and Bomag.

  • Compactors increase the load-bearing capacity of soil to sustain building load and traffic from vehicles. It also provides soil settlement and stability by reducing porosity, permeability, swelling, and retraction. Soil is commonly compacted underneath highways, roads, runways, buildings, and structures.

  • Compactors are among the heaviest construction equipment per sq. ft because of the need for static pressure applied to the soil. Rollers generally weigh between 1-20 tons.

  • All the steering controls for a compactor are located in the main cabin. Operators should have proper training and safety gear before operating a compactor. Before and after operating a compactor, it’s essential to perform appropriate maintenance checks and cleaning. Road rollers are operated from the control panel in the cabin. Here, you can set the vibration frequency and static force applied.

  • Consider the type of land you’ll be compacting before buying a compactor. With course grain soil like sand and gravel, smooth drum rollers are popular, while fine-grain soils like clay, sheepsfoot, or pneumatic rollers are effective. If you need deeper compaction below two inches, impact rollers are efficient.

  • The more hours a piece of heavy equipment logs, the closer any of its pieces will be to needing repair or replacement. Used models will need a thorough checkup of the cabin controls, hydraulics, drum integrity, cabin transmission, and engine.

  • Asphalt rollers can make anywhere from $36,500 to $60,000 per year working full-time.

  • Compaction is one of the most important steps in construction, meaning qualified compactors are in high demand. Employers will ask if you have a few years of experience in the industry, the required license classifications, a high school diploma or GED, and appropriate knowledge of construction materials.
