ABSTRACT:
A lift truck mast arrangement minimizes stresses occurring in mast members using rearward chain anchor placement to apply a rearward counterbalancing moment to the mast so as to create a bending moment in portions of the mast below the instantaneous position of the load carriage which is substantially equal to the bending moment then occurring in portions of the mast above the load carriage.
