EFFECTIVE NOISE MANAGEMENT – THE ROLE OF REGULAR CRANE MAINTENANCE

Abstract

Noise is defined as any sound that has the potential to disturb humans. As one of the significant occupational health hazards on construction sites, different levels of noise are produced by different construction equipment. The noise level among crane operators varies between 74 – 97 dB (A), and at some points, it reaches the maximum level of 101 dB (A). Different research indicated that the crane operator’s noise exposure depends on the task, crane model, and quality of the crane cab insulation. This research highlights the importance of conducting regular crane maintenance, as it can positively affect the decrease of noise exposure of crane operators. The aim of this study is to represent key elements of cranes that produce high noise and how they should be maintained by defining methods, time frames, and instruments that will be incorporated into the management of workplace noise. Reduction in noise level is accomplished with regular lubrication of moving parts, replacing wear and tear components, and ensuring proper alignment and balance. Through effective noise management that includes consistent inspection and monitoring, noise damping measures, and a set of preventive measures, the noise levels are kept within safe limits, lowering health risks to workers, such as hearing loss and other health issues. Implementing different preventive measures, such as predictive maintenance, scheduled servicing, and training for crane operators and maintenance staff, results in a quieter and safer operational environment.
