The invention discloses a chassis active floating structure of an overhead working truck and the overhead working truck. The chassis active floating structure comprises a chassis body, a front supporting leg, a rear supporting leg, a front wheel mechanism, a rear wheel mechanism and a steering mechanism; the chassis body is provided with a floating multi-way valve; the front supporting leg is rotatably connected with the chassis body through a first connecting shaft; the front supporting leg is connected with the chassis body through a floating oil cylinder; the rear supporting leg is rotationally connected with the chassis body through a second connecting shaft; the rear supporting leg is provided with a valve rod matched with the floating multi-way valve; the floating multi-way valve controls a floating oil cylinder to execute corresponding actions according to the telescopic change of the valve rod; the front wheel mechanism comprises a left front wheel and a right front wheel; andthe rear wheel mechanism comprises a left rear wheel and a right rear wheel, and the steering mechanism is arranged between the left front wheel and the right front wheel. According to the chassis active floating structure of the overhead working truck, the chassis body is rotatably connected with the front and rear supporting legs, so that the front and rear supporting legs can be leveled; and byarranging the floating multi-way valve, the valve rod and the floating oil cylinder which are matched, the leveling function of the chassis body is achieved.
