Risk Management and Excavator Downtime Analysis

Abstract

Nowadays, safety and sustainable business success cannot be viewed in isolation. Risk assessment is a prerequisite for adequate planning of prevention of destruction of critical potentials, as well as preparation of a strategy for response to failure in the context of prevention of consequences. An important part of all construction equipment maintenance is proper record keeping, but it is not done often in practice although it is a prerequisite of proper risk management. Proper maintenance of excavators maximizes fuel efficiency and reduces operating costs as well as equipment failure. The aim of this paper is to present the missing facts, to propose the methodology to be applied and show and analyze results obtained on excavator down time analysis and risk management. This research analyzed the structure of downtime and consequences in excavator work in six large Serbian companies during a period of one year. Delays in the observed transport and mining machines were classified according to the type of downtime: technological downtime, power / electricity downtime, mechanical downtime, misuse due to abuse, organizational downtime and downtime due to external influences. In this research, the frequencies of downtime were monitored by the stated categories of downtime. The consequences of the identified delays were then assessed, and the risk calculated.
