Abstract
The purposes of this study are to design an internet of things - based monitoring system to meet safety requirements for human and environment, and to perform simulations and experiments on a laboratory scale gantry crane. In this study, several sensors were used, namely a lidar sensor to detect the safe distance of the gantry crane, a gyro sensor to measure angle of the load to achieve a stable position and an RFID sensor to detect the spread position of containers and a load cell to measure weight of the load. Hoist and trolley encoders are used to detect the position spreader. All sensors will be connected to the controller and the stored data will be sent to the server via a LORA (long range radio) based communication system. The results of this sensor reading will be presented in a web-based dashboard monitoring system. Features of this monitoring system are equipment functions, alarm journals, notifications of spreader conditions and crane performance which will make it easier to monitor crane work systems in real time. The monitoring system was examined through laboratory scale experiments. Results of the experiments are presented and discussed.
Keywords: anti - sway, anti - collision, gantry crane, monitoring system.
