The lifting device comprises scissor type components and a power-driven device which controls opening and closing movements of components on layers of the scissor type components. The scissor type components comprise a top scissor component, a middle scissor component and a bottom scissor component. Inner arms and outer arms of the scissor type components are hinged with fork arm pin shafts in a movable mode. The scissor type components on the upper layer and the lower layer both are hinged with the fork arm pin shafts in the movable mode. The power-driven device is the electric-hydraulic pusher. The electric-hydraulic pusher is used as a lifting power device, and just needs to be connected with a circuit system to control power supply. Therefore, product structure is greatly simplified, and energy sources are saved, cost is reduced, and assembly, maintenance and overhauling are convenient. Working oil route of the electric-hydraulic pusher circulates in a non-pressure sealed steel cylinder, so oil can not leak, dust can not be absorbed, water can not enter the working oil route, the interior of the working oil route can not be rusted, and service life of the working oil route is long.
