Comparative study of factors affecting productivity and cycle time of different excavators and their bucket size

Abstract

Earthmoving and constructing equipments have evolved significantly during the past century. In every construction project some type of excavation must be performed. Excavators are primary earthmoving machines and equipment used to excavate earth and related materials. Contractors generally depend on their experience for selecting the right excavator for a job. Hence there is a need to build an understanding of how machine usage affects performance, extending across productivity. This study focuses on study of actual productivity against the theoretical productivity to demonstrate the loss of productivity. This real time monitoring of the heavy equipment can help practitioners improve machine intensive and cyclic earthmoving operations.
