Abstract
The invention relates to handling equipment. A double-girder overhead crane has two span beams combined into half-bridges with end beams. One arm of each span beam is installed hingedly on the end beam, and another arm is fixed. The half-bridge are connected by ties. Each tie by one end is connected to the upper part of hingedly located arm of the span beam. Technical result: elimination of twisting stresses, which occur in the span beams of crane during its operation, as well as uniform distribution of load on the crane track wheels. In addition, the invention provides a significant reduction of the deviation of distance between rails installed on the span beams and exclusion of transverse displacement of the half-bridges relative to the crane runway.
