or Bianchi linkages. These were in the form of an inverted triangle, reaching down from the high-mounted motor jackshaft to the wheel axle line. The Ganz form was used on the Hungarian-built Les Belles Hongroises 2BB2 400 locomotives for the French PO. This had four links forming the triangle, with the two upper vertices mounted to the locomotive frame (through a short swinging link) and to the jackshaft crankpin. The lower apex of the triangle contained a short triangular link, which linked the sides of the triangle to the wheel crankpin. By tilting this link, the suspension movement was absorbed. This linkage ran well at speed and as it was composed entirely of pivoting joints with no sliding, there was no lost motion. It was however complex, heavy and unbalanced. The Kandó linkage was similar in compensation, but the upper vertices were carried by a pair of motor jackshafts. The only one of these linkages with a widespread or long service life was the symmetrical, and better-balanced, Bianchi linkage, used in Italy.
