FIELD: lifting and transportation engineering. ^ SUBSTANCE: proposed end beam of bridge load-lifting crane contains metal structure with running wheels with shafts mounted in bearing units, at least one of which is mechanically coupled with drive mechanism. Beam is sectional, consisting of three parts including middle module and two end-face modules connected to middle module by detachable joint. Each end-face module is made in form of housing accommodating running wheel. Housing contains at least upper, rear and side walls. Middle module contains support member in form of vertical support plate rigidly fastened to its end-face surface. Said plate is congruent to rear wall of housing of corresponding end face module. Middle module is provided with additional support member in form of horizontal support plate rigidly fastened to its end-face surface, said plate being congruent to upper wall of housing of end face module. Joint of said horizontal support plate and end-face surface of middle module is reinforced by stiffening ribs welded to its upper surface and upper surface of middle module. ^ EFFECT: facilitated assembling, increased rigidity. ^ 5 cl, 5 dwg |
