An industrial truck of the narrow-aisle type having an upright rigidly connected to the frame of the truck and a drive unit pivotably connectible to the frame in certain selected rigid angular relationships in order to vary between predetermined limits the vertical angularity of the upright. The latter connection includes adjustable rigid connection members or struts mounted inwardly of the sides of the truck so that the upright can be securely mounted inwardly of upright members of the frame whereby to increase the lateral rigidity of the upright by adding thereto at least partially the lateral rigidity of the frame.
