Cradle trip bar limits(cradle bottom limit)

  • The purpose is to stop hoisting-down the cradle when the bottom of the cradle experiences an obstruction.
  • This may occur due to following reasons
    • An open window is in the line of the descending cradle.
    • A protruding obstruction from fa├žade below the cradle.
    • When the cradle reaches the ground level.
    • When the cradle rests on the roof floor during parking, hoisting further down by over ridding the trip bar will loose\n the tension in the wire ropes which would hamper the set routing of the wire rope through the sheaves.
