DOZER PRODUCTION EFFICIENCY
GIVEN
D9N Dozer (Fig. 7.14)
Move 2000 LCY
Distance - 400 ft. (Fig. 7.14)
Grade - 1% uphill (Table 7.2)
Material - Loose stockpile (Table 7.2)
Operator Skills- Excellent (Table 7.2)
Actual Time Working - 50 min/hr (Efficiency)
Operator Technique - slot dozing (Table 7.2)
Visibility - N/A (Table 7.2)
Material Weight- 2100 lb/CY (standard weight is 2300. Divide 2300 by material
weight to get the factor)
Transmission - Direct drive (Table 7.2)
Dozer Blade - Straight blade
D9N Book Efficiency (Fig. 7.14) X above factors = Actual Efficiency
Factors: grade x material weight x operator x type material x operator technique x
visibility x efficiency x transmission x type blade
Efficiency x Factors = Actual Efficiency = ,
