The invention relates to a super-lift pull plate bracket assembly which comprises a pull plate bracket and a pull plate bracket supporting part, wherein the pull plate bracket is detachably connected to the pull plate bracket supporting part; in the non-operating state, the pull plate bracket can retract into the pull plate bracket supporting part and is fixed relative to the pull plate bracket supporting part; in the operating state, the pull plate bracket can extend out of the pull plate bracket supporting part and is fixed relative to the pull plate bracket supporting part; in the non-operating state and the operating state switching process, the pull plate bracket and the pull plate bracket supporting part can move relative to each other. The invention also provides a crane and a method. The needed space is reduced when the pull plate bracket is switched by adopting a retraction form under the condition that the pull plate is supported, interference between the pull plate bracket and other structures is effectively avoided, and convenience and large space are provided for the design of other structures.
