  • a cable drum according to the invention comprises two round gables or flanges and a central body positioned between the gables/flanges around which central body a cable is positioned during use.
  • the document GB 832110 discloses a cable drum suitable for receiving material in extended lengths such as cables or hoses, the drum comprises two side metal members 11 held in parallel or substantially parallel relationship at a predetermined distance by readily removable tie rods 16. Adjacent the peripheries of an inner surface of a hub part 12 of each side member Hare formed opposed annular recesses in the form of grooves 21. The grooves 21 are disposed radially outwardly of the tie rods 16 and are adapted to retain and engage ends of wooden battens 22 which extend round the tie rods 16 constituting a cylindrical body of the drum.

  • the length of the central body 1 extending on the external side of the flange will depend on the material constituting the central body 1 and of the size of the cable drum, primarily the diameter/perimeter and length of the central body 1.
  • a groove 4 constituting the locking means may be as near to the end of the central body 1 as possible to reduce material consumption, but the length of material left between a groove 4 and the end of the central body 1 must be adequate to withstand the pressure of the cable reeled on to the cable drum and pushing on the flange 2 when the cable drum is in operation.
  • the flange 2 may fit tightly into the groove 4 or the flange 2 may be smaller or narrower than the groove 4 in which case it may be necessary to fit a wedge or the like into the groove 4 together with the flange 2 to keep the flange 2 in correct and fixed position.
