<p>A lifting platform to be attached to a vehicle and arranged to be raised and lowered vertically and pivoted about a horizontal axis by means of lifting and pivoting means, the lifting platform comprising a frame provided with lugs for the lifting and pivoting means, material filling the empty spaces within the frame, and an enclosure part made of glass fibre or other fibre material and resin, the enclosure part surrounding the whole structure. To improve insulation and strength properties, the frame (1) occupies only a fraction of the volume of the lifting platform. Most of the volume of the lifting platform is occupied by an integral composite construction (7) formed by glass fibre or other fibre material, resin, and a core structure, so that a seamless construction composed of glass fibre or other fibre material and resin also encloses the frame (1), simultaneously adhering to the frame (1) so as to be integral with it, thus covering the whole lifting platform in a seamless manner.</p> |
