Abstract

Un metodo y aparato para operar un dispositivo elevador de carga para mover una carga y mantener la carga estable. En la tecnica convencional, una carga suspendida elevada o descendida tenia la tendencia de moverse desde su posicion deseada, conforme el fluido hidraulico en el sistema se enfriaba, por ejemplo, una condicion de deslizamiento adhesivo. La presente invencion controla la presion de fluido en el sistema elevador y compensa la presion de fluido para adaptar cualquier caida de presion debida al enfriamiento del fluido. De este modo, la carga se puede mantener efectivamente estable en una posicion deseada, y se puede evitar la condicion de deslizamiento adhesivo.
