端梁部分在起重机中有着重要的作用，它是承载平移运输的关键部件。端梁 部分是由车轮组合端梁架组成，端梁部分主要有上盖板，腹板和下盖板组成；端梁是由两段通过连接板和角钢用高强螺栓连接而成。在端梁的内部设有筋，以端梁架受载后的稳定性。端梁的主要尺寸是依据主梁的跨度，大车的轮距和小车的轨距来确定的；大车的运行采用分别传动的方案。在装配起重机的时候，先将端梁的一段与其中的一根主梁连接在一起，然后再将端梁的两段连接起来。The end beam plays an important role in the crane, and it is the key part to carry the translational transport. The end beam part is composed of wheel combined end beam frame, and the end beam part mainly consists of upper cover plate, web plate and lower cover plate; The end beam is composed of two sections connected by high-strength bolts through connecting plate and angle steel. The reinforcement is set inside the end beam to ensure the stability of the end beam frame after being loaded. The main dimensions of the end beam are determined according to the span of the main beam, the track gauge of the crane and the track gauge of the trolley; The crane is driven separately. When assembling the crane, first connect one section of the end beam with one of the main beams, and then connect the two sections of the end beam.
