The invention discloses a cab having an overturning function. The cab comprises a cab body and a chassis machine frame. One end of the cab body is hinged to the chassis machine frame, the other end of the cab body is detachably installed on the chassis machine frame, and the cab body is provided with a force application mechanism far away form one end of the cab body hinged to the chassis machine frame. A supporting mechanism is further arranged between the cab body and the chassis machine frame. By adoption of the cab having the overturning function, during maintenance, the cab body is overturned and then can be maintained; compared with a conventionally dismantled cab, the cab not only greatly facilitates maintenance, but also is high in use safety, and the time for dismantling the cab is greatly saved. A floor of the cab body does not need to be provided with a maintaining hole, the sealing performance of the cab body is greatly improved, noises in the cab body are reduced, and the driving comfort is also effectively improved.
