The invention discloses a hoistway elevator with a rear-mounted traction machine for building construction. The hoistway elevator comprises the traction machine, a sky beam, a traction medium, a cageand a counterweight. A ridge spar is fixed to the upper end of a building hoistway, and the traction machine is arranged on a support outside the hoistway. A first pulley is arranged at the top of a cage, and a seventh pulley is arranged on a counterweight; a second pulley and a third pulley are arranged on the ridge spar, and a rewinding wheel is arranged at the bottom of the hoistway; one end ofa traction medium is led out from the traction machine, wound around the rewinding wheel, the second pulley and the first pulley, led upwards and fixed; the other end of the traction medium is led out from the traction machine, wound around the rewinding wheel, the third pulley and the fourth pulley, led upwards and fixed; and the hoistway elevator has the advantages of being high in safety, convenient to maintain and low in noise.

    本发明公开了一种曳引机后置式建筑施工用井道升降机,包括曳引机、天梁、曳引媒介、吊笼及对重;天梁固定在建筑物井道的上端,曳引机设置于井道外的支架上;所述吊笼的顶部设有第一滑轮,对重上设有第七滑轮;所述天梁上设有第二滑轮和第三滑轮,井道的底部设有复绕轮;曳引媒介的一端自曳引机引出,绕经复绕轮、第二滑轮和第一滑轮后向上引并固定;曳引媒介的另一端自曳引机引出,绕经复绕轮、第三滑轮和第四滑轮后向上引并固定;本发明的升降机具有安全性高、维保方便、噪音小的优点。
