The invention relates to a vertical component transportation platform for a fabricated building. The problem that the position is inconvenient to adjust during vertical component transportation at present is effectively solved. According to the technical scheme, the vertical component transportation platform comprises a bottom frame, two vertical guide frames are arranged on the bottom frame in aleft-right spaced mode, a supporting frame capable of moving up and down is mounted on the inner side of each guide frame, a driving device is mounted on each supporting frame, and a transportation platform body is erected on the two supporting frames. The transportation platform body comprises a horizontal bottom plate, wherein two bases which are arranged in a left-right spaced mode and can moveleft and right are arranged on the bottom plate; two vertical clamping plates are mounted on each base; the two clamping plates are symmetrically arranged front and back and can move towards each other or away from each other; and a center line in the left-right direction is marked on the upper surface of the bottom plate. Through the special transportation platform body, vertical components canbe accurately placed at the determined position of the transportation platform body, subsequent hoisting and assembling are facilitated, the transportation time is greatly saved, the labor amount is reduced, and the construction efficiency is improved.
