采用新型高分子合成材(cai)料，在井(jing)道環境不易老化(hua)、耐磨(mo)損(sun)(sun)、抗腐蝕(shi)。增加減震(zhen) 吸音(yin)結(jie)構，避免異響(xiang)，降低(di)運行噪音(yin)。采用模塊化(hua)結(jie)構，便于安裝維保。采用 模塊化(hua)結(jie)構，可單獨更(geng)換受(shou)損(sun)(sun)位置部件，降低(di)物料更(geng)換成本(ben)。 

New type of polymer composite materials, in the shaft condition,it is not easy to aging, wear resistance,corrosion resistance. Additional sound-absorbing module,for reducing ride noise. Rather modular structure is convenient for installation & maintenance, can replace the inoperative parts separately for reducing the material cost.
