The invention relates to the technical field of cranes, in particular to an auxiliary arm system and an arm rack system. The auxiliary arm system comprises an auxiliary arm and an auxiliary arm anti-backward-tipping device. The first end of the auxiliary arm anti-backward-tipping device is hinged to the first end, used for being connected with a main arm, of the auxiliary arm. The position of the second end of the auxiliary arm anti-backward-tipping device can be changed along with the auxiliary arm at different operating angles. In addition, an auxiliary arm support, an auxiliary arm front pulling plate, an auxiliary arm rear pulling plate and the like can constitute an integrated structure together with the auxiliary arm and the auxiliary arm anti-backward-tipping device. The integrated auxiliary arm system can achieve integral hoisting, integral dismounting and mounting and integral conveying of the auxiliary arm system, on one hand, auxiliary arm dismounting and mounting working condition time can be effectively shortened, and a crane with the auxiliary arm system can be switched flexibly between a main arm working condition and the auxiliary arm working condition; on the other hand, conveying of the auxiliary arm system can be further facilitated, so that labor intensity is relieved and working efficiency is improved.
