Safe organization of work on disassembling crane structures with regard risk-oriented approach

An important applied task to ensure occupational safety during construction and installation work in the conditions of existing enterprises is being solved. The purpose of the work is to determine the requirements for the safe organization of work during the dismantling of crane structures in existing production facilities. Object of study: design and technical documentation for the dismantling of crane beams in the conditions of the existing workshop. Subject of research: safe organization of construction and installation works in the current production environment. Overhauls and maintenance of equipment should be carried out in accordance with the developed and approved projects for the organization of work. Projects for the organization of work should indicate measures to ensure safe working conditions. Repair and technological documentation should contain: technological maps, technology notes, flow diagrams (repair steps), work schedules, albums of fixtures, tools to be used; lifting equipment, cargo sling albums, safety performance posters. A process chart has been drawn up for the dismantling of split steel crane beams with a span of 12 m. Due to the limited space, it has been proposed to dismantle large blocks of crane beams using hoists. The organization and technology of the construction process are described. The composition of the map includes: preparing the unit for dismantling; unfastening the block; dismantling and lowering the block; preparation of reference points for the installation of a new block. The technical and economic indicators of work are calculated: labor costs for dismantling blocks of crane beams, the need for machines, equipment, tools, inventory, devices, and operational materials. A work schedule has been drawn up. The work defines the requirements and limitations when performing construction and installation works. The analysis of harmful and hazardous production factors with regard risk-oriented approach. Instructions have been developed for labor protection during the dismantling of crane structures.
