What are the factors to consider then during the selection process? The two basic factors which should be taken into consideration are: -

The cost per unit of excavation and
The job condition the machine will work in
Lets discuss more in details these two factors. The meaning of cost per unit of excavation means how much does it cost to excavate per unit volume of the material found in the job site. The factors to take into account when working out the cost per unit of excavation are :-

• The size of the job, as a larger job may justify the higher cost of a large machine.
• The cost of transportation ( larger ones more cost)

In quarry works, there is the combined cost of drilling or blasting to be considered. If a large excavator is used, these costs may be less than if a small one as a large machine will handle bigger rocks better than a small one. Hence a large machine may permit savings in drilling and blasting costs.
