(一) 目前物流输送系统中的垂直输送机械仍大多选用链传动斗式提升机,在大运量时则多用高速带传动斗式提升机,它的断面尺寸小,节省地面面积;提升高度大,特别在应用夹钢芯的输送带以后,最大运量可达1500(m~3/h),最大提升高度可至350(m)。斗式 (A) At present, most of the vertical conveying machines in the logistic conveying system still use the chain-driven bucket elevator. In large capacity, they use the high-speed belt-driven bucket elevator, which has the advantages of small cross-sectional area and large floor area. Especially after the steel belt is applied, the maximum capacity can reach 1500 (m ~ 3 / h) and the maximum lifting height can reach 350 (m). Bucket
