The three major advantages
Polyurethane material layer, no need of lubrication
The service life is 2-3 times of the traditional steel wire ropeMore flexible, increases with the driving wheel contact area,more energy-efficient, more efficient.
采用稀土永磁同步无齿轮主机(高效PM永磁同步无齿轮主机)， 没有碳刷,不产生炭灰，内置式碟型制动器使运行更加安全、可靠;体积比相同负载下的传统主机小70% ;永久密封轴承无需油脂润滑,保证机房清洁;摩擦系数更高的复合钢带,有效的将主机动力传递到轿厢，提高运行效率，比传统有齿轮主机更加节能。
It applies rare earth permanent magnet synchronous and gear-less host (effective PM permanent magnet synchro-nous & gear-less host) without carbon brush. It thus does not produce carbon ash. Internal disc type brake bringsabout the more secure and reliable operation. Its bulk is 70% smaller than traditional host under same load.Permanently sealed bearing needs no grease lubrication. It ensures a clean machine room with the higher friction-al coefficient composite steel band. It effectively transfers the host motives to elevator car. Therefore, it enhancesthe running efficiency. It saves more energy than traditional geared host.
