新型滾輪通過輪轂上的機(ji)械結構與(yu)彈性體固定的免粘膠設計 , 可 以防止彈性體脫(tuo)落(luo)，提高(gao)了(le)滾輪的 使用壽命(ming)，減少工(gong)作人(ren)員對該電梯(ti) 用滾輪的拆(chai)解和組裝工(gong)作，節省人(ren)工(gong)成本，也減少維保人(ren)員在電梯(ti)井 道內停(ting)留時間，降低安全(quan)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.
