A survey of technical efficiency in crane systems using POET structure

Abstract

Aiming at operating characteristic of the rubber tyre gantry crane (RTG), the present development aiming to propose an ESS (double power) energy saving system of RTG, which uses a battery pack as the main supply or control. The battery pack may supply all electric operations of RTG for a period of time, realizing the complete matching between the output power supply and the equipment control demands for the whole process to increase energy efficiency, achieving recovery and recycling for the RTG braking energy. Due to the challenge of demand side management, the RTG crane system will be reconsidered from the POET (performance, operation, equipment, and technology efficiency) outlook, showing the possibilities and would be a control of engineering approach for the efficiency of energy as well as demand side management. Once the storage system is put into operation, it would run the most efficient economical fuel consumption area, achieving the highest fuel efficiency.
