The invention discloses overturning lifting equipment, being provided with eccentric tumblers, wherein two ends of the eccentric tumblers are provided with hanging pillars used for fixing lifting ropes. The principle that speed rate changes are different when concentric circles of different radii rotate is used, and the fast changed lifting ropes pull a weight, so that turning torque is generated on the gravity center of the weight, and the weight is overturned. The overturning lifting equipment is high in mechanization automation degree, and can replace many tedious intermediate links in manual work; mechanical labor liberates hand operation, and the labor efficiency is improved.
