Definitions

  • the mast profiles When all parts have been lowered and the mast is therefore in its lowest position, all parts of the mast profiles will be lined up at the top, whereas at the base, the inner profile(s) extends between the tyres and wheels, and the outer one not.
  • the outer mast profiles are partially or entirely positioned above the wheels or tyres to create a wider opening to the inner mast section.
  • the increased mast opening offers a significantly better view of the forks compared to the conventional forklift mast with comparable clearance height.
  • a comparable lifting height can easily be re-established by adding additional shorter mast parts outwardly of the inner mast part.
  • the telescopic mast further includes a fork carriage, adapted to carry at least one single fork, clamp, or other attachment for carrying a load.
  • This fork carriage can be attached to the inner mast part, when the outer mast part's lower end is adapted to be attached to a vehicle, such as a forklift truck, preferably with the option of being tilted with respect thereto.
  • the fork carriage can also be attached to the outer mast part, when only the inner mast part and not the outer mast part's lower end is adapted to be attached to a forklift truck.
  • a general benefit of telescopic masts for forklift trucks is that an increased lifting height does not need to result in an increased height of the forklift truck. There is some freedom in design as to whether the innermost mast part or the outermost mast part is attached to the truck. As a consequence the fork carriage will then be carried by the other of the inner and outermost mast part.
  • the invention thus relates to a new specific construction of the outer mast part i.e. the outer mast parts for forklift trucks, reach trucks, stackers and otherwise of machines which move pallets and/or goods in a vertical manner, with a particular purpose of creating a better view through the mast of the goods to be moved or lifted.
  • the outer mast part i.e. the outer mast parts of a triple mast
  • the outer mast part are positioned partially or entirely above the tyres which causes the mast profiles to be a bit wider apart, thus resulting in a wider opening in the inner mast part.
  • the wider opening provides a significant improvement in visibility of the forks and the load to be lifted. Therefore, an important aspect of this invention is positioning the outer mast profiles entirely or partially above the tyres or the conveying means of the forklift truck.
