The Manufacture Of RTG Double-speed Generating Device Based On Super-capacitor

Rubber Tyred Gantry Crane is one of main equipments for shipping and land operation in Container Terminal, also is the most fuel-consuming equipment in the container handling equipment. Besides the vast cargo operation, tyre crane operating characteristics are the fundamental reasons. Tyre crane using the diesel generator power, and diesel generator no-load running at high speed all the time waiting trucks'operating intermittence, result in the unnecessary waste of diesel. As in recent years the international crude oil prices continues to rise, how to reduce tyre crane (RTG) fuel consumption cost becomes the prominent contradictions and problems in specialized container terminal energy consumption of equipment management and operation cost management. Therefore, more and more domestic terminals realizing the seriousness and urgency of the problem, are actively exploring different energy saving new ideas, new technology, new management system to solve the problems above, such as the use of electricity instead of diesel generating sets for the tyre crane power supply. " electricity instead of oil" project, using the speed according to the load, which can be adjusted in a wide range of new engines and methods.This article from the container terminal handling process and container crane technical characteristic proceed with, analysis put forward tyred crane of double speed power energy-saving new ideas, and in this way under the guidance of the system design, hardware design and selection, PLC programming, installation debugging, system performance and energy saving effect testing, the ultimate success and achieved good economic and social benefits.
