Abstract: A conveying system for trestle frames of scaffolds to be utilized and transported as well as stored in an upright position. The conveying system included holding rails of a rack-like structure, with the rails being arranged in pairs and engaging with teeth thereof beside ends of scaffold tubes and, respectively, lower cross connections of the trestle frames. The conveying system also includes lower holding rails provided with receiving recesses for cross connections of the trestle frames. The trestle frames can readily be threaded in place and the transport pallets can be taken up by forks of forklift truck through apertures provided in the trestle frame, with the apertures enabling the forks to be inserted in the longitudinal and transverse directions thereby facilitating handling and transportation of the transport pallets by forklift trucks.
