The invention discloses a hoistway
elevator for construction. The hoistway
elevator comprises a building hoistway, a
sky beam, a traction medium, a traction
machine, a cage and a counterweight; the
sky beam is connected to the top end of the building hoistway, and the traction
machine is connected to the lower portion of the building hoistway; and the
sky beam is fixedly connected with a friction wheel and is rotatably connected with a second guide wheel, a third guide wheel, a fourth guide wheel and a fifth guide wheel, one end of the traction medium is connected to one end of the sky beam, and the traction medium sequentially bypasses the friction wheel, the cage, the second guide wheel, the third guide wheel, a driving wheel of the traction
machine, the fourth guide wheel, the fifth guide wheel and the counterweight from the end until the other end of the traction medium is connected to the bottom face of the other end of the sky beam. According to the hoistway
elevator for construction, the plurality of guide wheels and the traction medium are adopted to enable the cage to be located at a movable
pulley, so that the traction capacity of the traction machine is doubled, the traction efficiency is improved, and the
operation safety of the elevator is improved.
