Construction Equipment - Theory & Concepts

Selection, economics, and productivity of heavy construction equipment.

Calculate the productivity of heavy earthmoving equipment based on capacity, cycle time, and efficiency factor.

Bucket Capacity (

V

)15 m³

Cycle Time (

t_{\text{cycle}}

)5 min

Operating Efficiency (

E

)85%

load

Ideal Production

180.0 m³/hr

P_{\text{ideal}} = V \times \frac{60}{t_{\text{cycle}}}

Actual Production

153.0 m³/hr

P_{\text{actual}} = P_{\text{ideal}} \times \frac{E}{100}

P_{\text{actual}} = V \times \left( \frac{60}{t_{\text{cycle}}} \right) \times \left( \frac{E}{100} \right)

V

= Capacity (m³)

t_{\text{cycle}}

= Cycle Time (min)

E

= Efficiency (%)
