液压电梯最早出现于18世纪40年代,近50年来它有了显著的改进,使用日益广泛。在二次世界大战以前,美国便把它用在六、七层以下的低层建筑物里。近十几年内,西欧和日本也大量的采用。以西德为例,西德在最近的10年里,电梯的年产量平均为16000台左右,其中包括客梯、货梯和杂物梯等,而液压电梯约占2000～2500台,即占总台数的15%左右。如除 Hydraulic elevator first appeared in the 1840s, it has been significantly improved in the past 50 years, and its use is more and more widely used. Before the Second World War, the United States used it in low-rise buildings below the sixth and seventh floors. In the past decade or so, Western Europe and Japan have also adopted a large number of them. In West Germany, for example, the average annual output of elevators in West Germany during the last 10 years is about 16,000 units, including passenger elevators, cargo elevators and debris elevators. Hydraulic elevators account for about 2000-2500 units, About 15% of the number of Taiwan. If removed
