  • the wedge members 7 then return to the first unlocked position within the recess 8 to thereby allow for the lifting assembly 2 to be extracted from the passage 11 .
  • the present invention provides a quick lock and unlock lifting system that can reduce the time required to plan a lift, and reduce the number of personnel required for that lift.
  • the lifting system will also have a higher load capacity than conventional hooks. It is estimated that the load capacity will be around 5000 metric tonnes. This reduces or eliminates the need for pre-lift analysis prior to a heavy lift.
  • the wedge members 7 will be under a compressive load during lifting, it is not necessary to use a high strength material to manufacture the wedge members 7 leading to lower manufacturing cost.
  • the shape of the receptacle housing 3 and main body 5 is inherently strong and can therefore be made from normal strength material.
