The invention provides a heavy-load type cross beam lifting appliance which can solve the technical problem that in the using process of a cross beam lifting appliance, a pin hole of a lifting frame is not easy to align with a pin hole of a lifting lug. The heavy -load type cross beam lifting appliance comprises a main beam, cross beams and lifting frames, the cross beams are installed at the two ends of the main beam respectively, and the lifting frames are installed at the two ends of the cross beams respectively. The heavy -load type cross beam lifting appliance is characterized in that at least one cross beam is in running fit with the end part of the main beam, and the lifting frame comprises an upper hinged hanging support and a lower hinged hanging support; The upper end of the upper hinged hanging support is in running fit with the end of the cross beam, and the lower end of the upper hinged hanging support is in running fit with the upper end of the lower hinged hanging support. The lower end of the lower hinged hanging support is provided with a pin hole. According to the heavy-load type cross beam lifting appliance, through rotation between the lower hinged hanging support and the upper hinged hanging support, rotation between the upper hinged hanging support and the cross beam and rotation between the cross beam and the main beam, position deviation is eliminated, and the lifting efficiency is improved.
