Bucket Capacity/Material Density Selection Guide
t
Rock Mining Applications only, for Coal Mining contact your Cat representative.
The following table provides a guideline for bucket selection based on various material densities and estimated fill factors.
Based on the new ratings, fill factors are expected to be 110-120% in cohesive materials with easy digging, 100-110% in
ypical shot rock loading, and 90-100% in poorly shot rock with large rocks and difficult penetration. For many mining
applications, the 994F standard lift is matched with the 19 m3(24.5 yd3) rock bucket and the high lift is matched with the
17 m3(22.5 yd3) rock bucket.
