The invention discloses a hydro-pneumatic suspension system and engineering machinery, and relates to the technical field of engineering machinery. The hydro-pneumatic suspension system comprises a first suspension oil way and a second suspension oil way. A first suspension oil cylinder, a first control valve and a first energy accumulator are arranged on the first suspension oil way; a second suspension oil cylinder, a second control valve and a second energy accumulator are arranged on the second suspension oil way; the first energy accumulator is connected with a rod cavity of the second suspension oil cylinder and is connected with a rodless cavity of the first suspension oil cylinder through the first control valve, and the second energy accumulator is connected with the rod cavity ofthe first suspension oil cylinder and is connected with the rodless cavity of the second suspension oil cylinder through the second control valve. The hydro-pneumatic suspension system provided by the invention has a better pressure maintaining effect, and the performance of engineering machinery can be greatly improved.
