过去由于思想、技术、资金等方面原因,很少有人对电梯客流情况做交通分析,而是习惯于每5000m~2设一台电梯,多数出现电梯不够用。深圳有些办公楼设两台电梯,几乎天天乘客排长队候梯。长时间满负荷运行,电梯不但经常出故障,也大大降低了使用寿命。电梯工作制与每小时启动次数关系极大,目前最常用为:240次/小时、180次/小时和120次/小时的工作制,经实际检测,有的单位竟达360次/小时之多,致使过热保护经常跳闸,电梯停止运行。因而就
In the past, due to reasons such as ideas, technology, and funds, few people did traffic analysis on the passenger flow of elevators. Instead, they used to set up an elevator every 5000m2. Most elevators were not enough. Some office buildings in Shenzhen have two elevators, and passengers are standing in long queues almost every day. For long periods of full-load operation, the elevator not only fails but also greatly reduces its service life. The elevator work system has a great relationship with the number of starts per hour. Currently, the most commonly used is: 240 times/hour, 180 times/hour, and 120 times/hour. With actual testing, some units have reached as many as 360 times/hour. As a result, overheat protection often trips and the elevator stops operating. Thus
