Super-lift on-load walking lifting method for large crawler crane in coke oven modification project

A superlift on-load walking and lifting method for a large crawler crane in coke oven transformation engineering is characterized by comprising the following steps: a, selecting the crawler crane according to the distance between a slide wire and a coke oven, the lifting capacity, the lifting radius, the lifting height, the size of a single-truss main truss component and the gravity center of the component, b, assembling a greenhouse main steel truss section between the outer side of the slide wire and a vestibule, and c, assembling a main steel truss section between the outer side of the slide wire and the vestibule. D, the crawler crane is driven to a standing point; e, the main truss is lifted to move towards the east by a certain distance; f, the end table crawler crane and the intermediate table crawler crane lift the main truss to move; g, rotating arms of the two crawler cranes are adjusted; and j, the lifting radius of the 800t crawler crane of the spacing platform is 18m. The method has the advantage
