Claims

[Scope of utility model registration request]

This is a lift-up device for a lift-up crane that raises the crane by sequentially attaching additional masts to the lower end of a mast that has a boom at its upper end, and the effect of the crane's own weight on the lower end of the opposing sides of the mast and the additional mast. A lift-up device for a lift-up crane, comprising a support device that supports the vicinity of each line, and a lifting jack having a stroke longer than the length of the mast to which the support device is provided at the tip.
