The invention discloses a chassis leveling system for a mixture arm high-altitude operation vehicle. Vertical oil cylinders and horizontal oil cylinders are communicated with an oil tank through an eight-connected electromagnetic reversing valve, an overflow valve and speed control valves, and a double-shaft tilt sensor is installed on an auxiliary frame; horizontal extend-in-place detecting switches are installed on the side faces of supporting leg boxes of the auxiliary frame respectively, horizontal extract-in-place detecting switches are installed on the lower faces of the supporting leg boxes of the auxiliary frame respectively, vertical extract-in-place detecting switches are installed on installing plates of the vertical oil cylinders respectively, tyre off-the-ground detecting switches are installed on installing plates arranged above tyres respectively, and vertical touch-the-ground detecting switches are installed at ends of horizontal supporting legs; the eight-connected electromagnetic reversing valve, the speed control valves, the double-shaft tilt sensor and the detecting switches are connected with a PLC. Manual work control is replaced with automatic control for chassis leveling, real-time leveling for a chassis is conducted by driving leveling mechanisms such as the detecting switches, the eight-connected electromagnetic reversing valve and the PLC, the leveling efficiency is improved, and the leveling precision is improved.
