Research of system of energy recycling on Rubber-Tyred Gantry crane

In order to solve the problem that the existing rubber-tyred gantry (RTG) crane consumes massive generating/braking energy through resistance, produces plenty of heat, causes excessive fuel consumption and exhaust emission during working, the relation of energy flows of the existing system is analyzed and the value of the improvement of energy-saving is confirmed in the paper. The constitution and principle of the RTG energy recycling system are proposed. The topology and principle of the bi-directional DC/DC converter are anatomized. The method of voltage balance and the result of simulation of storing-energy supercapacitors are given in the end.
