The invention discloses a special crane for hoisting aluminum profiles. Lifting hydraulic cylinders are arranged on a table board of a hydraulic platform base, and stress of the lifting hydraulic cylinders is even. Pulley blocks are correspondingly installed on the lifting hydraulic cylinders. According to the structures of the pulley blocks, each hydraulic cylinder is provided with the two corresponding pulley blocks, and the two corresponding pulley blocks are arranged at the two ends of each hydraulic cylinder respectively; the pulley blocks close to a slideway are static pulley blocks, and the pulley blocks on the other side move along with stretching and retracting of the hydraulic cylinders; a steel wire rope is vertically downwards connected and fixed to a tackle in the slideway; the two sides of the tackle are each provided with two wheels arranged with one above the other; the slideway is welded to the two sides of a main beam; a bridge is composed of end beams, the main beam, a walking board, handrails and the slideway. A hydraulic station is placed on the walking board and located in the middle of the driving side of the walking board. A cab is arranged on the left side of the crane and located under the driving side of the walking board. Limit switches are installed right in front of the movable pulley blocks.
