RISK ASSESSMENT AND PREVENTION FOR INTERNAL CLIMBING CRANES IN HEIGHT-RISE BUILDING

Abstract

This research aims to: 1) Analyze factors affecting the risk of using internal climbing cranes in high-rise buildings in Bangkok. 2) Assess the risks associated with using internal climbing cranes in high-rise buildings in Bangkok. 3) Analyze laws and regulations related to the use of internal climbing cranes in high-rise buildings in Bangkok. 4) Propose guidelines for risk reduction and safety enhancement when using internal climbing cranes in high-rise buildings in Bangkok. This quantitative research collected data from a sample of 40 individuals with experience using internal climbing cranes, drawn from four sites in Bangkok. A questionnaire was used as the data collection instrument, and risks were prioritized using a 5x5 matrix. The research findings revealed the following: 1) 4 aspects factors were found to impact risk: 1.1) Structural Condition: This includes the condition of nuts and bolts, and a lack of pre-use inspection due to insufficient maintenance after operation. 1.2) Personnel: Operational staff and supervisors were found to violate regulations. 1.3) Construction Management: The process for recruiting and selecting operators did not meet established acceptance procedures. 1.4) Environment: There were significant impacts from dust and noise during operations. 2) Risk Assessment: The assessment showed that regular pre-use inspections are not conducted, and regulations are frequently violated. 3) Recommendations: The study recommends annual inspections and personnel training to clearly highlight the importance of these measures in accident prevention.
