General combination method for super-lift mast, crane and boom

The invention provides a general combination method for a super-lift mast, a crane and a boom, and belongs to the technical field of engineering machinery. The super-lift mast comprises a mast body, the first end of the mast body is provided with a first interface structure, and the first interface structure is suitable for being connected with the upper end of a rotary table or a main jib of the crane. A first pulley structure and a first installation part suitable for installing a second pulley structure are arranged at the second end of the mast body. According to the super-lift mast, the first interface structure is arranged at the first end of the mast body, the first installation part for installing the second pulley structure is arranged at the second end of the mast body, and therefore after a pulley is installed on the first installation part of the super-lift mast, the super-lift mast can also be used as a variable-amplitude fly jib and a light main jib, and the universality of the boom is high.
