Definitions

  • the present invention relates to an expandable mandrel spool for a spool provided with at least one mandrel mounted on a frame, the mandrel having movable jaws between a loading position in which the jaws are retracted and a position of use in which the jaws are expanded and maintain the coil in a substantially horizontal axis.
  • the reels are stored and transported in a standing position, their axis being horizontal, or in a supine position, their axis being vertical. In the upright position, they can be gripped by the forks of a forklift to be loaded directly onto the horizontal-axis mandrels. In the supine position, they are raised flat by the forks of a forklift and must be tilted a quarter of a turn before being loaded on the mandrels.
  • This reversal operation is dangerous and carried out most of the time either by suspending the hook of a traveling crane, or directly by the forklift.
