利用液压传动技术驱动的电梯卿液压电梯）在国外早已出现并已成熟。据报道，在7到10层楼以下的中、低层电梯中采用液压电梯已相当普遍。在一些工业发达的欧美国家，新装电梯中，液压电梯的占有率竟达50～70％。这是因为液压电梯具有许多优点：1）不需在建筑物顶部设置电梯机房
The hydraulic elevator driven by hydraulic transmission technology has long appeared and matured abroad. It has been reported that the use of hydraulic elevators in the middle and lower elevators below the 7th to 10th floors is quite common. In some industrially developed European and American countries, the share of hydraulic elevators in newly installed elevators has reached 50-70%. This is because the hydraulic elevator has many advantages: 1) It is not necessary to set the elevator room at the top of the building.
