龙门吊起升高度限位器的选用及设置

龙门吊起重机起升机构的起升高度限位装置是特种设备安全技术规范中要求的重要保护装置之一,一般场合集装箱龙门吊只需设置一套起升高度限位器,为了防止一套起升高度限位器失效时可能带来的吊具冲顶的安全事故隐患,很多龙门吊还设置了第二起升高度限位器。通过两种不同形式的起升限位器的设置,双重保护,提升机械安全性。

The hoisting height limit device of the hoisting mechanism of gantry crane is one of the important protective devicesrequired in the safety technical specification of special equipment. In general, only one set of hoisting height limiter is required forcontainer gantry crane. In order to prevent a set of lifting height limiter failure from bringing hidden trouble with the ceiling, manygantry cranes also installed the second height limiter, through two different types of hoisting limiter settings, dual protection, so as toimprove mechanical safety.
