由于桥式机械起重机的两端坐落在高大的水泥柱或者金属支架上,形状似桥。桥式机械起重机的桥架沿铺设在两侧高架上的轨道纵向运行,可以充分利用桥架下面的空间吊运物料,不受地面设备的阻碍。在交通建设中,该设备主要用于桥梁预制、安装及吊运等。 Because the bridge mechanical crane at both ends of the tall cement column or metal bracket, shaped like a bridge. Bridge mechanical crane bridge along the track laying on both sides of the elevated longitudinal run, you can take full advantage of the space under the bridge lifting materials, unobstructed by the ground equipment. In traffic construction, the equipment is mainly used for prefabrication, installation and lifting of bridges.
