Abstract: This study was conducted to make a limited evaluation of the Holland vertical-cut belt loader on overburden and in situ coal. The evaluation was based on observations and data from various field demonstrations of the loader, articles from various industrial publications, physical and mechanical characteristics of two loader configurations, and engineering properties of in situ coal. The two loader configurations evaluated were the loader with Caterpillar D9G and Fiat Allis 41B tractors as prime movers. Estimates of earthmoving performance were made for the two configurations using the Army ground mobility methodology. The method applies to moving soil; however, it was modified to consider coal moving capabilities. The predicted performance was within the manufacturer's estimated range but closer to the conservative side of the range. Properly monitored field tests are needed on the vertical-cut belt loader to properly tune existing methodology and develop a reliable earthmoving prediction scheme.
