Definitions

  • rollers of the pulley block should be able to handle pulling of up to 6 km or more of cable through the pulley block by use of a pre-installed stringing wire.
  • Fig. 4 shows schematically a front view of a pulley block according to an embodiment of the invention comprising a lock bolt with a locking mechanism and an adjusting bolt,
  • Fig. 1a and 1b shows a front view and a side view, respectively, of a pulley block 10 according to an embodiment of the invention with the at least one gate roller 30 in closed position
  • Fig. 2 shows a front view of a pulley block 10 according to an embodiment of the invention with the at least one gate roller 30 in open position.
  • the pulley block 10 is suitable for being suspended or fastened above ground to a structure and may for this purpose be provided with a fastening arrangement 12.
  • the invention is based on automatic closing of an entrance to a pulley block 10 in order to eliminate the need for manual assistance to install the cable or wire 60.
  • a guide arm 40 for the helicopter, or other type of aircraft ensures that when the cable or wire 60 is laid onto the guide arm 40, the cable or wire 60 will move towards the entrance 51 and thus be guided into a channel 50 made up of rollers 20, 30 of the pulley block 10.
  • the upper and lower horizontal rollers 20 should be rotatable about their respective longitudinal axis in order to ease pulling of the cable 60 through the enclosure 50 of the pulley block 10, however preferably also the vertical rollers 20 and/or the gate rollers 30, are rotatable.
