The chassis of a forklift truck includes a front assembly and a rear assembly movable toward and away from each other between an extended stable normal working condition and a contracted compact condition for storage or transport of the forklift truck. The front assembly includes driven front wheels, standard upright mast and double-acting lift jack for the fork carriage movable along the mast. The rear assembly includes the operator compartment, rear axle assembly for the rear wheels and mechanism mounting the rear axle assembly for vertical movement relative to the operator compartment between a raised normal working position and a downward-projected position. The rear assembly also includes a landing wheel mounted in front of the rear axle assembly at a location above the rear wheels when the rear axle assembly is raised. Projection and retraction of the rear axle assembly in cooperation with movement of the front and rear assemblies toward and away from each other and movement of the fork carriage along the mast permits self-loading and unloading of the forklift truck from one horizontal surface to another, such as onto and off of the bed of a transport vehicle.
