Design and Implementation of Automatic Stacking Crane Laser Positioning Sensor in Teluk Lamong Terminal

The problem experienced by PT Terminal Teluk Lamong is that every rainy season, the symeo radar positioning sensor on the gantry automatic staking crane is damaged by lightning. The symeo sensor is a positioning sensor that uses a radar system operating at a frequency of 57-64 GHz, which is very vulnerable to damage from lightning. This is due to the high-energy electromagnetic waves produced by lightning, which are in the same frequency range as the sensor's operation. When lightning occurs in the vicinity of the sensor, the strong radiation generated can interfere with the electronic components of the sensor, causing damage to the sensor. From this problem, the Sick DL1000 laser positioning sensor was chosen, which operates with a laser system that is reflected to the reflector and read back by the sensor to measure the distance of the crane from the water side to the land side. Sick DL1000 is also equipped with various safety ratings compared to symeo which is only IP67. Although Sick DL1000 is more expensive than symeo, Sick Dl1000 is very reliable when bad weather and lightning. proven by the beginning of installation from August 2023 to July 2024 there has been no damage to the sensor. PT Terminal Teluk Lamong gets a saving cost of 37% in one year for the maintenance of Automatic Stacking Crane.
