摘要
超载限制器是起重设备在作业过程中进行自动监测、报警、断电保护的装置,它根据所吊重物的额定重量做限制设定,当起吊重量达到限定值或超过限定值时,迫使吊钩不能上升只能下降,放弃对超载货物的吊装。本文通过实例介绍超载限制器在起重机控制系统中的电气、机械设计以及安装后的调试。
Overload limited machine is a automatic monitor, warning, cutting power protection installment when the hoist equipment carries on in the work process, it acts according to hangs the heavy item＇s schedule weight to make the limit hypothesis, when the hoisting up weight achieves the limitation value or surp＆~ses the limitation value, it forces the lift hook not to be able to rise can only drop, gives up to the overloaded cargo hoisting, Through example this article introduces electricity, machine design as well as installment debugging of overload limited machine in hoist crane control system＇s.
