How to calculate productivity of construction equipment
like excavator, dozer, rock breaker, riper

Answer

For calculating the productivity we have to know the
capacity of Excavator.

Let me assume the capacity of the Volvo 210 excavator =
1.22 Cum.

Consider the efficiency as 75% (This may be changing based
on the type of material to be excavated)

Therefore, net capacity = 1.22*75%= 0.92 Cum.

time per swing(unload,swing,fill,swing) = 20seconds =>
20/60 = 0.33minutes

Consider 5 minutes rest taken by the operatoer per hour.

Therefore, no of cycles per hour = 55/0.33 = 165

capacity per hour = 165*0.92 = 151.8 Cum/Hour

In similar fashion for dozer and other equipment can be
calculated.
