每一种行走起重机都有不可避免的几何误差,又受到外力作用,行走方向总会偏离轨道,所以轨道起重机的行走必须靠其轨道来导向。起重机上承担导向任务的是行走轮凸缘或水平导向滚子。当行走方向发生偏差时,在起重机行走机构与轨道之间就产生了一个水平力系统。这些力中的一部分被传到起重机的承载结构上,计算结构时要加以考虑。计算这些力的实用方法已由西德计算标准DIN15018的第4.2.2“侧向力”一节提供了。 Every type of walking crane has inevitable geometric errors and is subjected to external forces. The walking direction always deviates from the orbit, so the orbital crane must be guided by its orbit. Crane to undertake the task of the steering wheel flange or horizontal guide roller. When there is a deviation in the direction of travel, a horizontal force system is created between the crane traveling mechanism and the orbit. Some of these forces are transmitted to the load-bearing structure of the crane and are taken into account when calculating the structure. A practical method of calculating these forces has been provided in section 4.2.2 “Lateral forces” of the DIN standard DIN 15018.
