ABSTRACT:
A load carrying arrangement for a lift truck includes two spaced apart hollow upright elongated members which are mounted on a mounting element that is displaceably mounted on the frame of the truck, and at least one load-engaging attachment which has at least one load-engaging portion and two mounting portions introducible into the interiors of the corresponding upright members through the open ends thereof to mount the load-engaging attachment on the upright members and thus on the mounting element. Fixing elements, such as pins or bolts extending through aligned bores in the upright members and in the mounting portions, positionally fix the mounting portions within the corresponding upright members. The attachment may be constituted by a pair of fork prongs each of which has a load-engaging portion and a mounting portion which is introducible either into the open upper end or into the lower end of the respective upright member, or a container spreader whose load-engaging portion is adapted to engage a container and whose mounting portions are introducible into the upper open ends of the upright members. Additional attachments having corresponding mounting portions may also be mounted on the upright members in the same manner. When at least one of the upright members is mounted on the mounting element for movement toward and away from the other upright member, a roller is arranged at the lower end of the movable upright member and engages a track arranged at the corresponding region of the mounting element, throughout the range of movement of the movable upright member.
