THE FACTORS INFLUENCING TO CRANE OPERATION IN ENGINEERING WORKS.

Abstract

This research aims to investigate the factors influencing the operation of cranes in engineering work through a quantitative study utilizing the Analytical Hierarchy Process (AHP). This tool systematically evaluates complex and interdependent safety factors, enabling structured decision-making and improving the precision in determining root causes affecting crane safety. questionnaire was completed by experts such as construction engineers, construction managers, safety engineers, and Tower Crane operators with more than ten years of field experience. The findings reveal that the enforcement of legal regulations and associated penalties is the most significant factor, with a weight of 68.92%. This is due to the legal requirement for employers to ensure that employees involved in crane operations comply with established safety standards. However, inefficiencies in law enforcement and the lack of stringent penalties for non-compliance have hindered effective implementation. The second most significant factor is the non-compliance of businesses and users with legal requirements, with a weight of 10.88%, followed by adherence to crane operation standards (10.46%) and the failure of crane importers to comply with legal requirements (9.74%). In Thailand, the Ministerial Regulation on Standards for Management, Operation, and Safety of Machinery, Cranes, and Boilers, B.E. 2564 (2021) serves as the principal legal framework guiding employers and users to ensure workplace safety. Despite this, government agencies responsible for oversight lack the effectiveness needed for law enforcement, leading to frequent crane-related accidents. It is recommended that government agencies adopt proactive measures, such as providing training and knowledge dissemination to businesses and operators, to enhance safety in crane operations.
