The manned lifting system comprises a crawling ladder and a platform arranged on the crawling ladder in a sleeving mode, a climbing-free device is arranged on the crawling ladder, a crawling ladder opening used for enabling the climbing-free device to penetrate through the platform is formed in the platform, a plurality of sensors are arranged at different preset positions of the crawling ladder respectively, and the climbing-free device can trigger the sensors respectively. An opening and closing device used for opening and closing the crawling ladder opening is arranged on the platform, the opening and closing device can receive sensing signals of the multiple sensors respectively, and the opening and closing device judges whether the crawling ladder opening is opened or closed according to the receiving sequence of the sensing signals of the multiple sensors. By means of the climbing-free device, the accident that when a worker leaves the climbing-free device and carries out maintenance work on a platform, carried tools fall off from a climbing ladder opening can be prevented.

    本发明公开了一种载人升降系统,包括爬梯和套设在爬梯上的平台,爬梯上设置有免爬器,平台上开设有用于使免爬器穿过平台的爬梯口,爬梯的不同预设位置上分别设置有多个传感器,免爬器能够分别触发多个传感器,平台上设置有用于开闭爬梯口的开闭装置,开闭装置能够分别接收多个传感器的传感信号,开闭装置根据多个传感器的传感信号的接收顺序来判断开放或者关闭爬梯口。本发明能够防止工作人员离开免爬器在平台上进行维修工作时,所携带的工具从爬梯口掉落的事故。
