BUCKET OVERLOADING RATIO OF MINING SIZE WHEEL LOADERS & LOAD DISTRIBUTION CURVES - A CASE STUDY
Abstract
It is
extremely important to monitor bucket payload of mining wheel loader in terms
of evaluating both performance of the operator and the equipment. Both
underloading and overloading should be avoided. It is better sticking to the
optimum payload recommended by the Original Equipment Manufacturer (OEM) which
represents the optimum load for the equipment. Neither overloading nor
underloading of wheel loader (WL) is recommended. Underloading is not good from
productivity point of view; whereas, overloading will be shortening the life
expectancy of the machine in the long run and lower the Mean Time Between
Failures, (MTBF).
A LeTourneau
L-1350 model (21m3) Electric Wheel Loader (EWL) operating in a gold mine in
Uşak, Aegean Turkey, was monitored via onboard device for five cases. The
payloads, overloads and critical overloads; load distribution curves of shifts
with respect to overloads investigated. The overload and critical payload
counts are given and ratios in total bucket counts are calculated and
illustrated for the cases reviewed.
