The invention discloses an external drive hoistway elevator with an underneath type traction machine. The elevator comprises a traction medium, a first reversing wheel set, a second reversing wheel set, the traction machine and a third reversing wheel set, one end of the traction medium passes through the traction machine and then is guided to the first reversing wheel set, the first reversing wheel set comprises a transmission wheel and a tensioning wheel, the traction machine is connected with a traction wheel, the traction medium bypasses the first reversing wheel set to be reversed and then is guided to the second reversing wheel set, the traction medium bypasses the second reversing wheel set to be reversed and then is guided to a cage of the elevator, a cage diversion sheave is arranged at the joint of the traction medium and the cage, and the other end of the traction medium passes through the first reversing wheel set and then is guided to the third reversing wheel set; and thetraction medium bypasses the third reversing wheel set to be reversed, then is guided to a counterweight block of the elevator and is connected with the counterweight block. The elevator has the advantages of being rapid in lifting, low in noise and stable in lifting.
