Abstract

Un sistema (10) de control de aterrizaje suave para un dispositivo (12) nivelador que opera para descender en forma automatica un miembro vibratorio (24) de una unidad (14) de cabeza niveladora hacia la union con una superficie de concreto en un momento y lugar en donde el miembro vibratorio no esta colocado sobre un area de traslape de concreto ya nivelado. El miembro vibratorio desciende automaticamente sobre le concreto recien colocado en o cerca de la union o la union en frio entre el concreto ya nivelado y el area del concreto recien colocado, para asi evitar hundimientos en el concreto ya colocado. Como opcion, el sistema de control de aterrizaje suave puede incluir un dispositivo sincronizador y puede descender el miembro vibratorio despues de un periodo de tiempo despues de un evento de activacion. Como opcion, el sistema de control puede detectar cuando el dispositivo de vibracion esta colocado en o cerca del concreto recien colocado y puede descender el miembro vibratorio en respuesta a tal deteccion.
