ELASTIC SYSTEM FOR TRACTION AND SHOCK GEAR (SIDE BUFFERS AND CENTER BUFFERS). STUDY OF LOAD PROTECTING DEVICES FOR PALLETISED LOADS THROUGH BUFFING TESTS.
The report contains a description of the various load protecting systems (with the exception of impact dampers with long stroke) for palletised loads in order to prevent damage. The systems studied can be subdivided into two groups, according to their operating principles, consisting in: (1) the creation of a rigid load forming a solid assembly with the wagon, to avoid any impact effects between wagon and load; (2) the dissipation of energy by the sliding of the load under simultaneous elastic storing of the impact energy. The tests have shown very clearly that the principle of the sliding load, for damage prevention does not lead to the desired effect in the case of palletised goods. Owing to the shifting of the various load tiers relative to each other and also because of parts of the load fallen from the pallets, difficulties are encountered during unloading using fork lift trucks, or this unloading procedure will even become impossible. The principle, consisting in the creation of a rigid load, forming a solid assembly with the wagon (Daberkow System with pre-loading of the goods through air cushion and the system with movable rigid partitions), gave good results during the buffing tests. However, the system based on the use of movabale rigid partitions has not yet reached its final stage of perfection and the performance of this system during the run could not yet be verified. The practical experience obtained from the Daberkow system hitherto has shown that the pre-loading also prevents the lateral sliding of the loads during conveyance.
