The invention provides a lifting and tipping hydraulic system of a cab and a control method of the lifting and tipping hydraulic system. Comprising a lifting hydraulic oil cylinder, a lifting hydraulic oil cylinder balance valve, a tipping hydraulic oil cylinder, a tipping hydraulic oil cylinder balance valve, a tipping hydraulic oil cylinder throttling valve, a first one-way valve, a one-way throttling valve, a hydraulic control stop valve, a lifting hydraulic oil cylinder throttling valve, a second one-way valve, an indoor manual control stop valve, an outdoor manual control stop valve, a hydraulic oil tank, a pilot control end and a high-pressure oil source. A tipping hydraulic control reversing valve group and a lifting hydraulic control reversing valve group; individual or combined actions of lifting and tipping of the cab are realized by matching with a special hydraulic system, and the control flexibility of equipment is improved. After equipment is abnormal, it is guaranteed that the cab can act orderly and reset stably, and high safety is achieved.
