Judging by the description, the breakdown occurred due to noncompliance with the rules and instructions. As a tire service engineer, I can say that I have seen this happen more than once. The wheel was incorrectly secured and may have exceeded the permissible diameter or weight limit. Unfortunately, it is unlikely that you will be able to assemble the rack yourself. Before use, it is best to read the user manual for CEMB USA C72 . They clearly describe all the parameters for installation and safe use to avoid such problems in the future. If the instructions are lost, I often recommend this website, ManualMachine. Generally, just follow the instructions, and the stand will work properly.
