Definitions

  • the deformation reducing means are arranged so that under load a deformation of one part of the cover acts against a deformation of another part of the cover, to reduce the overall deformation of the cover and hence reduce the permanent set recorded.
  • the first and second mountings are the mountings at each end of the longer side.
  • Fig. 3 shows one of the covers 12 on its own for clarity.
  • Each cover 12 includes a planar part 20 which in use forms an upper surface of the cover 12.
  • the shape of the planar part 20 is a right angled triangle, having a longer edge 50 and two shorter edges 52 of substantially equal length.
  • the angle between the longer edge 50 and each of the shorter edges 52 is approximately 45°
  • the angle between the two shorter edges 52 is approximately 90°.
  • Extending downwardly in use from each of the 45° corners 64 are first and second mountings 54, 55 respectively, and extending downwardly in use from the 90° corner 66 is third mounting 56.
  • Each of the mountings 54, 55, 56 is in the form of a protrusion, the mountings 54, 55, 56 together forming a non rock three point mounting for the cover 12.
  • the maximum length of the auxiliary beam 24 could be between 30 and 50% of the maximum length of the main beam 22, and in one example was approximately 40% of the maximum length of the main beam 22.
