Construction hoist

The utility model provides a construction hoist and relates to the technical field of constructional engineering construction hoists. The construction hoist aims at solving the problems that construction channels need to be set up between an existing construction hoist and the outer edge of a building structure lay by layer, great manpower and materials are wasted, and the construction efficiency is lowered. The construction hoist comprises a guide rail frame and a hoisting cage connected to the guide rail frame through a gear and rack transmission mechanism, the guide rail frame and the outer edge of the building structure are connected through a frame adhering to a wall, an outwards turning type channel device is installed at the position of a passage, close to the building structure, of the hoisting cage and comprises an outwards turning door hinged to the edge of a bottom board of the hoisting cage and an ascending door capable of longitudinally sliding along the passage of the hoisting cage, the closed outwards turning door and the ascending door can close the passage of the hoisting cage, and the height of the outwards turning door is greater than the distance between the hoisting cage and the outer edge of the building structure.
