<p>A lift cylinder (210) for a mast assembly of a vehicle, the lift cylinder comprising a cylinder housing (212) with a piston (214) received therein in which the piston is movable along an axis of extension between an extended position and a retracted position, wherein the piston (310) comprises an anisotropic composite material having a reinforcement phase (312), such as a graphite-epoxy sub-matrix, oriented along the axis of extension thereby increasing the buckling resistance of the piston. A lift truck comprising a mast assembly (122) having multiple telescopic sections (126, 128, 130) extendable via lift cylinders (172, 174) installed on the truck is also disclosed. 2 16 FIG. 5</p> |
