The invention discloses a telescopic type cross supporting beam relating to the technical field of lifting mechanical equipment. The telescopic type cross supporting beam comprises a cross beam provided with multiple groups of lifting lugs, wherein each group of lifting lugs comprise two lifting rings which are positioned on the upper side and the lower side of the cross beam and are correspondingly arranged; the cross beam is provided with a main beam and telescopic beams embedded in the two ends of the main beam; the connecting parts of the main beam and the telescopic beams are provided with positioning pin shafts penetrating through the main beam and the telescopic beams. Compared with the prior art, the telescopic type cross supporting beam disclosed by the invention has the advantages that the cross beam is provided with the main beam and the telescopic beams embedded in the two ends of the main beam, when goods with small lifting span are lifted, the need can be met only by using the main beam, so that the lifting weight is reduced and the lifting space is saved; and when the goods with large lifting span are lifted, the main beam and the telescopic beams are combined for use, the lengths of the telescopic beams extending out of the main beam can be adjusted and can form different lifting spans, so that the need for lifting the goods with multiple spans is met.
