不同动力系统下的叉车环保性能分析

For responding to the appealing of sustainable development, the analysis compares environmental performance of fork lift trucks, motivated by different power system. At the contemporary, the definition of environmental protection function is macroscopic, broad sense. Include the work efficiency of fork lift trucks, need of maintaining and supporting time and cost, the storage battery used of usage time and the brake efficiency can be placed into the category of environmental protection function. Engine powered fork lift truck does not have an absolute environmental protection performance, cause it uses non renewable energy resource,although it can make the tail spirit exhaust quantity to attain least through upscale launch machine. Only Electric Fork Lift Trucks have realistic value of environmental performance, when renewable energy resources, for instance, tidal energy, solar energy.etc, can one day put into practise instead of steam electric power generation. However，Electric Fork Lift Trucks’ environmental protection performance is inevitably relative to the power system.Those motivated by permanent magnet motor have the most superior environmental protection performance.
