Leveling tool for crane structural member

The utility model provides a leveling tool for a crane structural member, which belongs to the technical field of equipment leveling and comprises an upper pressing block, a lower pressing block and a middle pressing block, the middle pressing block is arranged between the upper pressing block and the lower pressing block, and inclined planes on the upper pressing block, the lower pressing block and the middle pressing block are mutually attached. Compared with a traditional mode that a jack is adopted for leveling, the leveling precision is improved, the leveling difficulty is reduced, a support or a base plate does not need to be used for supporting after leveling, and the leveling efficiency is effectively improved. 本实用新型提供了一种起重机结构件用调平工装，属于设备调平技术领域，包括上压块、下压块和中间压块，所述中间压块设置在上压块与下压块之间，上压块、下压块和中间压块上的斜面相互贴合。通过各压块之间的相互配合，相比传统的采用千斤顶调平，提高了调平精度，降低了调平难度，且在调平后不需要进行支座或垫板进行支撑，有效提高了调平效率。
