Definitions

  • the publication JP 2004 099193 A discloses a lifting chain provided with an elastic member to reduce the chain length at rest, and extend to a maximum length when the elastic member is in tension. Thus, an elongation is possible, but with a springback that can be violent or even dangerous.
  • the tensioner hook is provided by a locking hook at each end.
  • the bottom hooks of the two bungees are respectively fixed on the last third of chain with hook.
  • the crane operator ensures the decrease in the length of chain chases in the upper part for which become null leaving the tension to refer to the chains and not on the bungee cords.
