在建工部门,习惯于将支承起重机的轨道梁称之为吊车梁,本文以下就也将起重机梁称之为吊车梁。吊车梁的计算似乎是建工部门的事,其实作为一个起重机设计人员,也应关心它的支承结构,所以本文想从起重机设计的角度谈谈吊车梁的计算载荷,仅供建工部门的同志参考。吊车梁上作用有垂直载荷V,纵向水平载荷T(对吊车梁一般不予计算)及侧向水平载 In the construction sector, it is customary to call the orbital beam supporting the crane a crane beam, which is also referred to below as a crane beam in this paper. Crane beam calculation seems to be the construction department, in fact, as a crane designer, should also care about its support structure, so this article from the perspective of crane design to talk about the calculation of crane beam load, only for the construction sector comrades reference. The role of the crane beam vertical load V, vertical horizontal load T (generally not calculated on the crane beam) and lateral horizontal load
