The invention provides a construction hoist cage door opening and closing device which comprises a cage door, a cage frame and two sets of lifting assemblies, sliding rails are arranged on the two sides of the cage frame respectively, the cage door can reciprocate up and down along the sliding rails on the two sides of the cage frame, the two sets of lifting assemblies are located on the two sides of the cage frame, and each lifting assembly comprises a counterweight block and a steel wire rope; a driving assembly is arranged on the upper side of the cage frame, an output shaft of a driving motor of the driving assembly is connected with an input shaft of a speed reducer, two output shafts of the speed reducer extend to the upper sides of the sliding rails on the two sides respectively, two driving wheels are installed at the ends of the two output shafts of the speed reducer respectively, and one end of a steel wire rope is fixed to a counterweight block. The other end of the steel wire rope bypasses a driving wheel of the driving assembly and is fixed with the bottom of the cage door. The device has the advantages that the driving assembly is additionally arranged, and the opening and closing mode of the cage door is changed through cooperation of the driving motor and the speed reducer. A proximity switch, a pulley, a slow descending assembly and the like are added to achieve automatic opening and closing of the cage door of the building hoist and guarantee safety.
