The invention discloses a special crane provided with hoisting trolleys and used for an aluminum sectional material. The special crane comprises a crane body and a guide rail, wherein the crane body comprises a main beam, end beams, hoisting mechanisms and transmission mechanisms; and each hoisting mechanism comprises the hoisting trolley, a hoisting frame, a balancing weight, a chain and a hoisting main engine. According to the special crane, by using the hoisting trolleys provided with H-shaped groove steel, the structure of the hoisting trolleys is optimized; and the structures and quantities of screw rods, groove steel and sliding lifting hooks are reasonably set so that a previous screw rod stressing manner is converted into a manner that the hoisting trolleys bear all the gravity, and furthermore, the loads of the screw rods are greatly alleviated and the structures of trolley bodies are optimized and the whole performance of the hoisting trolleys is improved greatly. With the adoption of the special crane, the technical problems of the hoisting trolleys of an existing special crane for the aluminum sectional material that the structure is not reasonable, the operation not stable and the screw rods are easy to deform are solved very well.
