过坝提升机在机械传动、电气拖动方式上与矿井提升机相同，普遍采用微拖动装置、硬齿面行星减速器、盘形制动器及二级制动液压站，主轴装置的简壳直接加工绳槽并加过渡块，多数采用交流拖动。目前我国生产且投入运行的过坝提升机与同类型的矿井提升机相比，具有提升能力大，运? Over dam hoist mechanical transmission, electrical drag the same way with the mine hoist, commonly used micro-drag devices, hardened planetary gear reducer, disc brakes and two brake hydraulic station, the shaft device of the simple shell direct Processing rope groove and add the transition block, the majority of AC drag. At present, China’s production and put into operation over dam elevator with the same type of mine hoist compared with the lifting capacity, transport?
