新型滾輪(lun)通過輪(lun)轂上的(de)(de)機(ji)械(xie)結構(gou)與彈(dan)性(xing)體固(gu)定的(de)(de)免粘膠(jiao)設計 , 可(ke) 以防(fang)止彈(dan)性(xing)體脫落，提高了滾輪(lun)的(de)(de) 使用壽命，減(jian)少(shao)工作人員對該電梯 用滾輪(lun)的(de)(de)拆解(jie)和組裝工作，節省人工成本，也減(jian)少(shao)維保人員在(zai)電梯井 道內停留時(shi)間，降低安全風險。 

New roller can prevent elastomer fall off by means of the mechanical structure and elastomer fixed wheel surface viscose design,improve the lifetime of roller,reduce operator disassembly and assembly to save labor cost,also reduce the staying time inside of the elevator shaft and reduce the risk.
