The lift truck of the invention comprises a frame, a mast adapted to be lifted in relation to the frame, a fluid-operated cylinder for controlling the ascent and descent of the mast, a load-supporting platform rigid with the mast, a first pivot pin carried by the lower end of the mast and rigid with a movable slide block guided horizontally along the lower portion of the frame. The slide block carries the pivot pin of a positioning rod for positioning the load supporting platform and a supporting rod, having a length equal to one-half of the distance between the pivot pin of the mast on the slide block and the pivot pin of the load supporting platform on the mast, is pivoted to the mast and to the lower portion of the frame ahead of the slide block. |
