The invention discloses a people and goods dual-purpose vertical-transportation building construction elevator and belongs to the field of elevators. According to the people and goods dual-purpose vertical-transportation building construction elevator, a steel wire rope traction transmission mode is adopted, a single column and two cages are arranged, the two cages are arranged on the two sides of a main frame respectively, and each cage moves up and down along an angle iron guide rail on one side of the main frame through a pulley on one side of the cage; counter-weight pulley guide rails are arranged on the inner sides of the main frame, and counter weights move up and down along the counter-weight guide rails on the inner sides of the main frame through pulleys of the counter weights; a traction machine is positioned and installed at the top end of the main frame; one end of each traction steel wire rope is connected with the top of the cage on the corresponding side in a balanced and hanging mode; the tensile strength of each traction steel wire rope is equal to or higher than 1570 N/mm, and the safety coefficient of each traction steel wire rope is equal to or lager than 14.8; the weight of the counter weights is two fifths or half the sum of the weight of the cages and the rated deadweight of the cages. The weight of the cages and approximately half of the rated deadweight are balanced out by means of the counter weights, actual required driving power is greatly lowered, and operation is made stable and safe.
