  • Patent number: 6641357
    Abstract: A fork lift rack that includes a first beam, a second beam and at least two spacer elements which fix the first and second beams at a distance from and substantially parallel to each other is taught. The load-bearing fork members can be mounted on the first and second beams. The fork members can be displaced along the length of the beams. The fork members have first and second legs that extend in separate vertical planes. The fork members are designed such that the distance between the first legs is greater than the distance between the second legs when the two forks are mounted in place on the rack. The spacer elements have fastening devices which are intended to releaseably fasten the fork lift rack to a lift mechanism, the upper beam has a web and a flange which are joined to each other at an angle &agr; different from 90°. The upper beam is joined to each spacer element via the web. The web is directed away from the lower beam.

  • Patent number: 6533526
    Abstract: This invention relates to a displacement device mountable on a fork lift rack for allowing displacement of a lift member in a substantially vertical direction. The displacement device has a body with at least one elongated opening having its longitudinal direction in the vertical direction, a pin moveably received in the opening, and at least one coupler for connecting to the fork lift rack. A coupler of the fork lift member can be connected to the pin. Accordingly, the lift members can be inserted under an object that is placed on an inclined surface without having to tip the entire fork lift rack.
