自行式起重机有11种安全装置,本文简介中小型汽车起重机用水平仪、幅度指示器和起升高度限位器的维修。1.水平仪的调整与修理起重量≥16t的汽车起重机必须安装水平仪,现在有许多8t的汽车起重机也安装了水平仪。若水平仪失准,则说明吊重时转台处于不水平状态,将使起重机在回转时处于上坡或下坡状态,很不稳定,这样会加速回转机构制动装置的磨损。同时,如果失准严重,还会隐藏着事故祸患。 Self-propelled cranes have 11 kinds of safety devices, this article describes the use of small and medium-sized truck crane level, amplitude indicator and lifting height limiter maintenance. 1. Level adjustment and repair Car cranes with a weight of ≥16t must be equipped with level gauges, and now there are many 8t crane cranes installed. If the level of misalignment, then hanging when the turntable is not level, will make the crane in the slew uphill or downhill state, very unstable, it will speed up the wear of the rotating brake mechanism. At the same time, if misquisitions are serious, the accident will be hidden.
