The invention relates to a balanced suspension, and aims at solving the problems that: an existing balanced suspension is complex in structure, and tires are prone to being gnawed. The utility model provides the balanced suspension and an automobile crane, the balanced suspension comprises a plate spring, and a balance support in the middle of the plate spring is hinged to a plate spring support fixed on a frame; the front and rear ends of the plate spring are connected with lower supports on the lower sides of the end parts of axles; two upper thrust rods are used for connecting the thrust rod supports which are connected with the upper sides of the middle parts of the front axle and the rear axle with the frame respectively; and lower thrust rods are arranged on the two sides, and a thrust rod support on the lower side of the end of the front axle is connected with a thrust rod support on the plate spring support through the two lower thrust rods on each side. The balanced suspension has the advantages of simple structure, light weight and low cost, the problem of tire gnawing caused by relative displacement of the plate spring and the plate spring support is avoided, and the structure is more reliable.
