新型滾(gun)輪通過(guo)輪轂上的(de)機(ji)械結構與(yu)彈性(xing)體固定的(de)免粘(zhan)膠設計(ji) , 可(ke) 以防止彈性(xing)體脫(tuo)落，提高了(le)滾(gun)輪的(de) 使用壽命，減少工作人(ren)員(yuan)對該(gai)電梯 用滾(gun)輪的(de)拆解和組裝(zhuang)工作，節省人(ren)工成本，也減少維保人(ren)員(yuan)在電梯井 道(dao)內停留(liu)時間，降低(di)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.
