Abstract

A telescopic mast assembly for a fork-lift-truck comprises a fixed mast section (10) and two relatively movable mast sections (15, 16). A slidably mounted lifting carriage (26) is supported on the movable section (16) which is itself slidably mounted on the movable section (15). The carriage (26) is raised up the movable section (16) by a hydraulic cylinder (50) and the movable section (16) is raised up the movable section (15) by a hydraulic cylinder (40). The movable section (15) is raised up the fixed section (10) by a pair of cylinders which are arranged in series with the cylinders (50) and (40) so as to operate in sequence.
