CONSTRUCTION APPLICATION
1. Production per cycle (q)
q = q1 × K
where q1: Bucket capacity (heaped) (m3; yd3)
K : Bucket fill factor
- Bucket fill factor
The bucket fill factor varies according to the nature of material. A suitable factor can be selected from the table, taking into consideration the applicable excavating conditions.
2. Cycle time (Cm)
Cycle time = Excavating time + swing time (loaded ) + dumping time + swing time (empty)
However, here we use cycle time = (standard cycle time) × (conversion factor)
The standard cycle time for each machine is determined from the following table.
3. Job efficiency (E)
The
following table gives typical job efficiency as a rough guide. To
obtain the actual production figure, determine the efficiency in
accordance with actual operating conditions.
