A pantograph-type lifting system comprises a base; a platform connected to the base by a pair of levers each comprising a first lever and a second lever mutually hinged in a fulcrum, the first lever having a lower end hinged to the base, and an upper end sliding connected to the platform, the second lever having a lower end sliding connected to the base, and an upper end hinged to the platform in a fixed spot; a chain-type actuating system of the levers comprising one chain meshed with a first toothed pulley and with a second toothed pulley rotatable connected to the respective levers, the chain-type actuating system being configured to transfer the motion from motor means to the levers through the toothed pulleys in order to approach or move away the ends of the levers with a scissors-like movement to lift or lower the platform.
