The result consists in a further security margin. DISTRIBUTED LOAD CONCENTRADED LOAD TONNAGE ® PATENT RIF. EACH SINGLE PIECE Multiplyng the tonnage of each cross-piece by the number of the cross-pieces interested it gets the total tonnage of MULTIGRIL.

While in reality the load of a wheel is distribuited all over its trace. A better safety margin is obtained.
