The invention discloses a building construction hoistway elevator with an underneath type traction machine. The building construction hoistway elevator with the underneath type traction machine comprises the traction machine, a sky beam, a traction medium, a suspension cage and a counterweight; the sky beam is fixed to the upper end of a building hoistway, and the traction machine is fixed to thebottom of the hoistway; a first pulley is arranged at the top of the suspension cage, and a fourth pulley is arranged on the counterweight; a second pulley and a third pulley are arranged on the sky beam; one end of the traction medium is led out from the traction machine, led to the second pulley, wound around the second pulley and then led downwards to the first pulley, and the traction medium is led out upwards and fixed after being wound around the first pulley; and the other end of the traction medium is led out from the traction machine, led to the third pulley, wound around the third pulley and then led downwards to the fourth pulley, and the traction medium is led out upwards and fixed after being wound around the fourth pulley. The building construction hoistway elevator with theunderneath type traction machine has the advantages of high safety, convenient maintaining and low noise.
