Abstract

The purpose of this study is to develop and implement a vibration detection system using a triaxial sensor on the hoist motor of a Rubber Tyred Gantry Crane (RTGC). The method involves installing a vibration sensor on the electric motor to measure vibrations across three axes. The collected vibration data was stored in Comma Separated Values (CSV) and Java Script Object Notation (JSON) file formats and analyzed to classify the vibrations according to International Standardization Organization (ISO) 10816 standards. The results indicate that the highest recorded vibrations on the hoist motor were 5 mm/s and 7 mm/s, particularly during the combined movements of the hoist and trolley. These vibrations were influenced by the trolley reel panel and RTGC operating conditions, such as sudden torque changes due to braking. The real-time monitoring system performed well, with the website displaying real-time data and classifying motor conditions based on predefined thresholds. The classifications include good for vibrations <1.4 mm/s, satisfactory for vibrations <2.4 mm/s, unsatisfactory for vibrations <4.5 mm/s, and unacceptable for vibrations >7.1 mm/s.
