The invention provides an active-compensation-type tank lifting device. Consistency of positioning, weighing, ascending and descending in the lifting process of tanks can be effectively achieved. According to the technical scheme, the active-compensation-type tank lifting device comprises a tank lifting body, first guiding mechanisms, feed screw nut mechanisms and a driving mechanism; the two sides of the driving mechanism are each connected with the corresponding set of feed screw nut mechanisms, and each set of first guiding mechanisms is arranged above nuts of the corresponding set of feedscrew nut mechanisms; and the first guiding mechanisms are connected with the bottom of the tank lifting body, and the two sets of first guiding mechanisms are arranged in a relatively oblique mode toform a V-shaped structure so as to be matched with the V-shaped bottom of the tank lifting body.
