If the CG moves forward of the
drive axle, the truck tends to tip
forward (longitudinal). If the CG
moves outside of the stability
triangle, the truck tends to turn on
its side (lateral).

When the lift truck picks up a load, the truck and load have a new combined CG. The stability
of the lift truck is determined by the location of its CG, or if the truck is loaded, the combined
CG.
