Abstract

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. The utilization rate of the boom is increased, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a general combination method of a super-lifting mast, a crane and a jib. Background technique [0002] The jib crane has a large number of jibs and many types of combined working conditions. Different jib shapes have large differences due to weight, size and the weight and size of the accessories that match it, so they also correspond to different cranes. Focus on performance, and further correspond to different usage requirements and costs. With the development of all-terrain cranes to super-large tonnage, fixed jibs, tower jibs and luffing jibs have been applied to all-terrain cranes. Therefore, corresponding to different use environments and weights of hoisted objects, it is usually necessary to equip different jibs, and the versatility between different jibs is poor, resulting in waste of cost. Contents of the invention [0003] Therefore, the technical prob...
