有时由于工作需要,在一根较长的吊车轨道上,安装着两个或两个以上的电动葫芦,在工作中难免会出现撞击现象,致使齿轮箱和电机风叶损坏而影响生产,还会威胁人身安全。为了防止以上事故发生,我们安装了限位支架,如图1、图2所示。限位支架的尺寸,可根据电动葫芦的结构不同而确定,我厂使用的是天津产2T电动葫芦。 Sometimes due to work needs, in a long crane track, the installation of two or more electric hoist, in the work will inevitably be the impact of the phenomenon, resulting in damage to the gear box and the motor blades affect production, but also Threatening personal safety In order to prevent the above accident, we have installed the limit bracket, as shown in Figure 1 and Figure 2. Limit bracket size, according to the different structure of electric hoist to determine, I plant is used in Tianjin 2T electric hoist.
