The invention relates to the field of vehicles and discloses a double-cylinder lift comprising a frame, a first cylinder, a second cylinder, a support and a steady state controller. Two ends of the support are mounted on the frame through rotating shafts. The first cylinder and the second cylinder are mounted on the support. Jacking directions of the first and second cylinders are perpendicular to a rotating direction of the support. The steady state controller is connected with both the first cylinder and the second cylinder; oil feed is controlled for the first and second cylinders according to a tilting state of the support. When the first cylinder and the second cylinder move synchronously, the support never tilts. The invention further provides a vehicle. When the first cylinder and the second cylinder are asynchronous, the support deflects, and meanwhile, the tilting state of the support can be judged through the steady state controller; oil feed is increased for the tilting cylinders, the steady state controller distributes different oil feeds until that the support does not tilt as long as the support tilts, and motion synchronousness of the cylinders is ensured.
