The turnable cab greatly simplifies the process of maintaining and repairing the vehicle, which can be called as one of the most classical designs in the truck industry. At present, almost one hundred percent of cab-over-flat heavy cards all have a turning function, and even light cards which are rarely assembled with the function before increasingly adopt turning technology.

The truck cab has a heavy weight and is not turned over by manpower alone. Therefore, a set of power assisting devices is needed, and the power assisting devices can be divided into a torsion bar type and a hydraulic type in terms of working principle. The light truck generally uses a torsion bar type turnover mechanism, and the torsion bar type simply relies on one or two iron rods with better elasticity to provide auxiliary power, so that the cab is lifted manually.

The hydraulic turnover system, as the name implies, is a system that relies on hydraulic power to lift the cab. From the power source, the hydraulic flipping system can further be classified into manual and electric. Since the cab is not turned over much and manpower is sufficient, most heavy trucks now use a manual hydraulic turning system. The hydraulic tilting system has the advantage that the lifting force is large enough to cope with the tilting work of the cabs with various specifications, which is incomparable with the torsion bar type power assisting system. However, the hydraulic turnover system has the disadvantages that the structure of the hydraulic turnover system is too complex, the failure rate is higher than that of a torsion bar type, and the hydraulic turnover system has higher requirements on maintenance. The problem that the existing lining for the front overturning lever is worn seriously after being used for a certain time, so that abnormal sound is generated in a cab during driving; the above problems are urgently needed to be solved.
