An existing cast ingot lifting appliance is a pure mechanical lifting fixture or a hydraulic lifting appliance which has advantages, but also has defects. The invention provides a mechanical, hydraulic and electrical control combined lifting appliance, which has both the advantages of a mechanical lifting fixture and a hydraulic lifting appliance, and remedies the defects of the mechanical lifting fixture and the hydraulic lifting appliance, so that a cast ingot is firm, stable and safe in lifting and the operation is flexible. The technical scheme for solving technical problems is that the mechanical, hydraulic and electrical control combined lifting appliance comprises a mechanical drive system, a hydraulic system, an electrical control system, a remote controller and the like. The mechanical, hydraulic and electrical control combined lifting appliance is characterized in that a mechanical and hydraulic combined lifting fixture is formed by combing a mechanical lifting appliance with automatic clamping by virtue of gravity of lifted goods and a hydraulic lifting appliance with clamping by virtue of hydraulic pressure, and the hydraulic system is controlled by the electrical control system. The mechanical, hydraulic and electrical control combined cast ingot lifting appliance integrates advantages of the pure mechanical lifting appliance and the pure hydraulic lifting appliance, and removes defects of the pure mechanical lifting appliance and the pure hydraulic lifting appliance, so that the cast ingot is firm, stable and safe in lifting, and the operation is flexible.
