The invention provides a small-tonnage crane, a traveling beam thereof and a horizontal wheel device for the traveling beam. The traveling beam comprises a beam body, a left horizontal wheel device and a right horizontal wheel device are mounted on the beam body, each of the left horizontal wheel device and the right horizontal wheel device comprises a horizontal wheel carrier, a horizontal wheel and a horizontal wheel connecting frame, and each horizontal wheel connecting frame is fixedly arranged on the beam body integrally or in a split manner. A moving adjustment structure for guiding each horizontal wheel carrier to achieve guide moving adjustment on the corresponding horizontal wheel connecting frame along the left-right direction is arranged between the horizontal wheel carrier and the horizontal wheel connecting frame of each horizontal wheel device, and a fixing structure for fixedly assembling the horizontal wheel carrier and the horizontal wheel connecting frame when the horizontal wheel carrier with the horizontal wheel is adjusted to be in place by moving is further arranged between the horizontal wheel carrier and the horizontal wheel connecting frame. The traveling beam has the advantages that since the positions of the horizontal wheel carriers in the left-right direction can be adjusted through the moving adjustment structures, the horizontal wheel devices an be adjusted according to the practical conditions, and normal and effective operation of the horizontal wheel devices is guaranteed.
