The invention discloses a hydraulic lifting platform applied to a portal crane. The hydraulic lifting platform comprises a platform frame; guardrails are mounted on the outer side of the platform frame; a platform bottom plate is mounted at the bottom end of the platform frame; guide clamping plates are mounted at the two ends of the platform frame through plugs; the guide clamping plates are mounted on second guide rail plates; first sliding grooves are formed in the second guide rail plates; a mounting plate is mounted at one end of each second guide rail plate; supporting top plates are mounted in the middles of the mounting plates; and second guide rail plates are mounted on the sides, close to the back positions, of the bottom ends of the supporting top plates. According to the hydraulic lifting platform, the guide clamping plates are mounted at the two ends of the platform frame through the plugs, the guide clamping plates are glidingly connected with the second guide rail plates, sliding protruding blocks are welded to the two sides of the back of jacking lifting plates, the sliding protruding blocks slide in second sliding grooves in the second guide rail plates, through the design, the platform frame can ascend and descend stably, and the platform frame is connected with the jacking lifting plates through lifting ropes.
