Abstract

The invention relates to the field of hoisting-and-transport machinery. The purpose of the invention is to reduce the material intensity and labor-intensiveness of the manufacture of the crane girder. The crane beam contains the upper along with of two elements 1, between which there is a vertical wall 2 with a protrusion 7, lower along with 3, a rail of two plates 4 attached to the protrusion 7, and straightening gaskets 5. When exposed to crane loads in welded The joints 8 of the fastening of the elements 1cc to the wall 2 do not produce local stresses from the vertical crane load, t, k. it is transferred to wall 2. 1 Il. 00 SP

However, local bridge gantries do not arise to the structures of the crane runways1 to the wall 2. The strains from the vertical crane aim of the invention is to reduce the load, since it is transferred to the non-porous intensity and labor-consuming capacity produced directly to the wall 2. When exposed to the rail. loads the protrusions 7 of the wall 2 are elastically detached. The drawing shows a crane runway, which reduces the shock loads.
