A hydraulic elevating platform having no guide rails and an elevating method. A hydraulic power pack (1) drives three parallel hydraulic cylinders (2) to work synchronously, thereby implementing the rising and falling of an elevating platform (5); when the elevating platform (5) reaches a predetermined floor, an upper electric pushrod (5-12) pushes a pedal assembly (5-13) out, and then the pedal assembly (5-13) drives a pedal to rise by means of a pedal elevating system until the pedal is flush with the surface of a loading table (5-2) of the elevating platform (5); outswing doors (5-4) between the elevating platform (5) and a floor open to form pedal guardrails; then sliding doors (5-3) open and a man can step onto a stair via the pedal assembly (5-13). An eccentric loading adjusting means (5-9) eliminates eccentric loading to achieve balance about the center of gravity, thereby eliminating the eccentric loading of the platform. The elevating platform (5) is simple in structure, safe, reliable, and easy to maintain. The elevating platform (5), placed within a spiral stair, is convenient for movement of crowds and cargo delivery at certain scenarios and is widely applicable. The elevating method is simple to implement and effectively solves the eccentric loading problem caused by reasons such as outstretching of a pedal of a hydraulic elevating platform and uneven distribution of people on the elevating platform, so that the hydraulic elevating platform (5) is more stable and reliable during operation.
