Loading Shovel Buckets
The bucket weight is heavier than the tilt-dump bucket. However, its characteristics of vertical dumping provide the following features
• Accurate loading is possible, because it is easy to position the bucket on the dumping point.
• Load spillage is less.
• Larger dumping clearance permits easier loading on the hauler.
• As it is possible to more closely position the bucket over the hauler’s body, loading shock to the hauler can be minimized, extending the service life of the hauler.
• As a result of the above advantages, the cycle time is shortened.


Applications
O: General digging and Loading
A: Light material work (Specific gravity, 1.2 and less)
Q: Light material work (Specific gravity, 1.5 and less)
H: Heavy-duty work (Specific gravity, 1.5 ~ 2.0)




O: General rock bucket for digging and loading
H: Light material work
O: Heavy-duty work

Production
Estimated Hourly Production



** Bucket size: Heaped bucket capacity
*** Cycle time: Refer to the section 16A “Productivity”

Actual production = (Estimated Hourly production) × (Bucket fill factor) × (Job efficiency)

Bucket Fill Factor (K) (PC400~PC1800)


Job Efficiency(E)


Bucket Fill Factor (K) (PC1400~PC8000)*4
