Abstract This paper presents a case study that explores how operator digging style juxtaposes with mechanical capability for a class of hydraulic mining excavators. The relationships between actuator and digging forces are developed and these are used to identify the excavator's capability to apply forces in various directions. Two distinct modes of operation are examined to see how they relate to the mechanical capabilities of the linkage and to establish if one has merit over the other. It is found that one of these styles results in lower loading of the machine.

Additional Notes Paper considers operator use of a particular class of mining excavators juxtaposes with the mechanical characteristics of those machines. The significance of the work lies in providing understanding on how better to use excavators. The work is based on material from A.S. Hall's MPhil completed under the supervison of P.R. McAree.
