Identifying Job Risks Related to Overhead Cranes with the Help of Job Safety Analysis and Making Decisions about Them Based on MADM

The health of work locate and safety of people that deal with overhead cranes is important; and operation with overhead cranes encounter with many accidents. As a point, this study presents a new investigation in the area of work risk examination connected to overhead cranes by combining two JSA job safety analysis methods and MADM multi-criteria decision making model.

The method of gathering information encompasses interviews with operators and other people deal with this device, considering the records and documentation of the incident and identification of accidents, as well as observation of work process with the crane; and Analyzes performed by the Expert Choice software. The results exhibit that the injured current cables and course spread, isolation damage and current spread, as well as non-operation of sirens, levers, and pedals classify first to third amongst the risks link to overhead cranes, respectively. In addition, the putrefaction of the gears, the hard displacement of the gear, and the decrease in production efficiency take the twelfth ranking. The compatibility rate ascertains usage of the Expert Choice software in pairs of comparisons the options match in ۰.۰۳۱ that specify an excellence compatibility of the contrast. The present study showed the JSA technique is a definite and systematic technique to define and measure the existing or potential risks in each job and procedure, and in mixture with the AHP technique, it can successfully identify and prioritize the risks related to overhead cranes
