LIFT ARM CONTROL SYSTEM

摘要

A system for a loader (10) controlling movement of a lift arm (21) of the loader (10) near a limit of travel of the lift arm (21) receives a signal indicative of the loader engine speed and a signal indicative of actuation of a sensor on the lift arm. A controller (15) determines a lift arm command signal (51, 52) based at least upon the engine speed signal, and transmits the lift arm command signal (51, 52) to an electro-hydraulic system to control the movement of the lift arm (21) adjacent the limit of travel of the lift arm (21).
