Calculate Excavator Productivity Using Mathematical Formula

Tags: Excavator equipment used excavator functions used excavator parts2013-04-03

If you want to know exactly your used excavator productivity, some formula should be remembered in calculation. We know that the new ones have the introduction information for us. However when it is used for a period of time, the production is no more the previous one. So it is available if you have the necessary parameters. Another situation is that you want to buy a used excavator in market or online stores, then you want to compare their productivity before you buy it. The steps are followed.

Essentially, excavator productivity is typically measured by the volume of loose or rock soils the machine can displace in a hour of continuous operation. The methodology of calculating the productivity of an excavator emerged together with the first excavator machines. In other words, the productivity of an excavator is determined by the volume of the soil it can dig up in a minute. The calculations for excavator productivity are straightforward and can be simply completed on a standard calculator.

Firstly and primarily, formula is crucial in this calculation. Q = (60*q*z*n*kf) / kl, where Q is the productivity of the excavator, q is the capacity of each rotor bucket in cubic feet, z is the number of buckets on the wheel and n is the speed of rotation of the rotor, measured in revolutions per minute. kf stands for the filling factor of a bucket while kl represents the soil-loosening factor.

Then you are advised to gather the data from your machine. Such as the number of buckets on the wheel and the speed of rotation of the rotor from the operator's manual of your excavator as well as the capacity of each rotor bucket in cubic feet. The filling factor of the bucket and the soil-loosening factor can be determined experimentally.

Next, put the data that you collected into the formula. The final result is the productivity of your used excavator. Be careful in collecting  the data and pay attention to the calculation process. Make sure that the process is all the way right. As you purchase a used excavator, you can firstly calculate the productivity and compare the result.
