The invention relates to a roller device, an integrally-mounted transportation bracket and a crane. The roller device comprises a roller support, a lateral plate, a roller and at least two pins, wherein the lateral plate is fixed on one side of the roller support through the pins, and the roller can be selectively fixed at different positions between the roller support and the lateral plate through the pins of different heights so as to support a to-be-supported body at different heights. The roller device has the advantages that the lateral plate is fixed on one side of the roller support through the pins, the roller is fixed between the roller support and the lateral plate through one pin, the roller can be matched with the pins at different heights so as to change the height positions of the roller between the roller support and the lateral plate, the support heights of the roller can be adjusted, a reliable and stable support foundation is provided to the to-be-supported body of different heights under different work conditions, the matching structure of the roller and the pins is stable and easy to implement, mounting efficiency is increased, and mounting reliability is guaranteed.
