PRODUCTION EFFICIENCY STUDY ON LARGE-CAPACITY, RUBBER-TIRED FRONT-END LOADERS

TWENTY-SEVEN LARGE-CAPACITY, RUBBER-TIRED, FRONT-END LOADER OPERATIONS WERE STUDIED ON BOTH HIGHWAY AND NON-HIGHWAY CONSTRUCTION PROJECTS THROUGHOUT THE UNITED STATES. THESE FIELD STUDIES WERE CONDUCTED IN ORDER TO DETERMINE THE CAPABILITIES OF THE MACHINE IN LOADING BANK MATERIAL INTO OFF-HIGHWAY HAULING UNITS AND TO LOCATE THE DELAYS ASSOCIATED WITH THE OPERATION. PRODUCTION OUTPUT WAS MORE DEPENDENT ON AN ADEQUATE PAYLOAD PER LOADING CYCLE THAN ON A QUICK CYCLE TIME. EQUIPMENT AND MAINTENANCE REPAIR DELAYS TOTALLED OVER 65% OF THE MAJOR DELAY TIME. MINOR DELAY TIME WAS LARGELY DUE TO HAUL UNIT SHORTAGES AT THE LOAD SITES, AND THE IMPACT OF THESE DELAYS WAS DEPENDENT ON THE USE OF THE TIME BY THE LOADER OPERATOR. THIS REPORT IS INTENDED TO BE A WORKING MANUAL FOR USE AT THE FIELD OPERATIONS LEVEL BY HIGHWAY CONSTRUCTION CONTRACTORS. /DOT/
