Smart technologies are been extensively used in manufacturing processes in order to increase overall performance, an increasing focus is outlined also for supporting occupational and industrial safety. Applying smart technologies in the safety domain could contribute to increase the work place safety. This project aims to evaluate potentialities of adopting these technologies in a specific critical process in Automobile industry to prevent Electric hoist and Electric Monorail System (EMS) collision. The collision happen in the overhead equipment leads to electrical short circuits, Fire and property damages beyond the repair. Collision prevention in this kind of critical process is much needed to increase the work place safety. An automated collision prevention system based on smart technologies in supporting an efficient collision prevention process based on the literature review analysis. By using the statistical tool, Binary DOE (Design of Experiment) three critical factors like Speed of the EMS system, Distance to be maintained between hoist and EMS system during automatic operation, Types of sensors to be used for the collision prevention has been arrived. This auto collision prevention system detects the Electric hoist and Electric Mono rail System movement and its position in the bus bar system by monitoring its movements continuously through Sensors and Programmable Logic Controllers. If operator mistakenly operates any one of the both collision contributors (Electric Hoist or EMS) in the track change over area, the track change system interlock will show error indication in the operator panel. The Interlock system implemented with the usage of smart technologies which can prevent the collision and alerts to the operators while they do any errors via visual indicators. Thus, this auto collision prevention system helps to maintain the safety at the work place with the usage of smart technologies. Automatic forward or reverse operation of the EMS system at the track changer area will begin once the manual electric hoist clearance in the travel path of EMS and the track changer feedback. By implementation of this auto collision prevention system Lifting tackle collision between EMS system and manual Electric hoist has been reduced to zero.
