Typical Application Description
(relative to work application)
Low
Dig and carry operation from stockpiles to ground level transfer station. Low density, free
flowing ore and waste. Excellent draw point floor surfaces. Short haul distances: 25-100 m
(80-330 feet)
. Level roads with good surface conditions. Low load factor.
Medium Intermittent development/production loading into trucks/transfer station. Good digging with
well shot, low to medium density ore and waste. Average draw point floor surfaces. Medium
haul distances: 100-200 m
(330-660 feet)
. Poor road surfaces with slightly adverse grades.
Medium load factor.
High
Continuous production loading of trucks at or near maximum load height. Difficult digging.
Loading haul trucks. Rough draw point surfaces. Long haul distances: 200-300 m
(660-990 feet)
.
Poor haul roads with adverse grades. High load factor.
