The invention discloses a telescopic tower body of a small size tower crane. The telescopic tower body of the small size tower crane comprises an inner tower body, a middle tower body and an outer tower body, wherein the inner tower body can telescopically move inside the middle tower body, the middle tower body can telescopically move inside the outer tower body, four upper depended wheels perpendicular to one another are arranged at four corners of the top of the middle tower body and four corners of the top of the outer tower body correspondingly, slideways of the upper depended wheels arefour stand columns of the adjacent inner side tower bodies, four lower depended wheels are arranged at four corners of the bottom of the inner tower body and four corners of the bottom of the middle tower body correspondingly, and inner slidingways corresponding to the lower depended wheels are fixed to the inner sides of the adjacent outer side tower bodies. The telescopic tower body of the smallsize tower crane is compact in structure, reasonable in space arrangement, small in occupied area, flexible to operate, capable of rapidly, safely and stably adjusting three lifting heights of the tower bodies and suitable for working environments with different lifting heights.
