The present invention relates to a ceiling crane having a truss structure capable of reducing the construction cost by reducing the weight of the bridge girder and preventing deformation due to concentrated loads during the transportation of heavy objects. A ceiling crane having a truss structure according to an embodiment of the present invention includes a traveling rail installed on a wall so as to be adjacent to both sides of a building ceiling, saddles provided on the traveling rail and moved along the traveling rail, An overhead crane comprising: a bridge girder which is moved on a running rail; and a trolley which lifts a heavy object while moving along the bridge girder, wherein the bridge girder comprises an upper plate, A bottom plate disposed on the lower side of the upper plate so as to be symmetrical with respect to the longitudinal direction on both sides of the upper portion of the upper plate and a side plate provided at both ends of the upper plate and the lower plate to connect the upper plate and the lower plate, A plurality of interposed spaces are formed between the upper plate and the lower plate so as to be partitioned in the lateral direction The plate and the top plate arranged at regular intervals and such that the space between the lower plate delimited by the truss structure is characterized in that it comprises a wobble plate characters ∧ on both sides of the partition plate arranged in a repeated shape.
