This paper presents a progress report of our study of the front-end loader (FEL) roll-over instability problem and the development status of a stability indicator used to improve the safety of front-end loader operations. As this paper is being written the program is still active and progress is continuing. The contributing factors have been identified, the loader stability characteristics have been determined and several overturn warning indicators are being fabricated for installation for subsequent field evaluation.The indicator is sensitive to bucket load and position, pitch and roll angle, articulation angle and vehicle speed. The above signals are used as inputs to analog circuits which solve a correlation equation and compare the actual roll angle to the “critical” roll angle. The device displays a visual warning to the operator.
