Disclosed are a hydraulic lifting apparatus, a hydraulic lifting system having same, and a lifting cargo carrying platform. The hydraulic lifting apparatus comprises a double-acting hydraulic cylinder, a lower support base disposed at a lower portion of the double-acting hydraulic cylinder and used to support the double-acting hydraulic cylinder, an upper support base disposed separated from the double-acting hydraulic cylinder, and a cylinder head support base used for fixing the double-acting hydraulic cylinder. The hydraulic lifting system comprises four hydraulic lifting apparatuses as described above and a hydraulic system for providing hydraulic fluid for the double-acting hydraulic cylinders of each hydraulic lifting device. The hydraulic system comprises a vehicle-mounted hydraulic fluid circuit and an external hydraulic station disposed separated therefrom. The vehicle-mounted hydraulic oil circuit comprises a hydraulic locking element, a hydraulic synchronization element and a hydraulic reversing element. The lifting cargo carrying platform comprises a fixed platform, a lifting platform, a platform bracket and the described hydraulic lifting system. In the present invention, a hydraulic lifting apparatus and a hydraulic system separated from each other are used, such that the volume and dead weight of the vehicle-mounted parts are greatly reduced, thereby increasing the transportation and economic benefits.
