Research of Potential Energy Recycling System on Port Tyre Cranes

Port tyre cranes have the drawbacks of high energy consumption and serious pollution, whose potential is the most important latent energy being wasted. Some attempts to recycle the potential of tyre crane have attained certain energy-saving result, but their stability and reliability need to be verified. Based on the specific conditions of port tyre cranes with complex structure, a novel potential energy recycling system was proposed, with new applications such as a coaxial motor with dual armatures and variable torque and the nonlinear weighted coding dynamic magnetic technology. The results show that this system has characteristics of high energy utilization, excellent energy-saving effect and stability.
