塔式起重机是在施工现场使用较多的起重机械,相关规范都要求其必须装有各种限位装置,但对小车变幅的塔机并没有要求小车要装防断轴装置。许多企业生产的塔机没有此项装置,一旦小车轴断裂,就会导致小车带着吊钩和重物坠落,引发危险。根据这一情况,我们在长期的工作实践中,发明了一种简易的小车防断轴装置。这种装置制作简单,使用方便,能起到当小车断轴时防止小车坠落的作用。
Tower crane is used in the construction site more crane, the relevant norms require that it must be equipped with a variety of limit devices, but the trolley amplitude of the tower crane does not require the car to be equipped with anti-broken shaft device. Many companies do not have this tower crane installation, once the small axle fracture, it will lead to the car with a hook and heavy objects fall, causing danger. According to this situation, in the long-term practice of our work, we invented a simple car anti-shaft device. This device is simple to create, easy to use, can play a car when the broken axis to prevent the role of the car crashed.
