The utility model discloses a double-inclined traction elevator, and relates to a traction elevator running in a hoistway with two inclined angles. The traction elevator comprises a traction machine, a lift car, a counter weight, a traction rope used for connecting, and a pair of safety tongs connected on a straight beam; and the inclined angles in one direction can be formed by the plane of a base plate by utilizing rotating shaft fixing seats with different heights on the base plate, and the lift car is vertical to the ground. Two main guide rails and two straight beams are arranged by depending on the inclined hoistway, so that a rigid whole body formed by the base plate, a support frame and the straight beams can move synchronously along with the up and down movement of the straight beams, and the lift car positioned on the base plate is vertical to the ground all the time. The elevator can run on the hoistway with the two inclined angles, thus effectively ensuring the lift car is vertical to the ground all the time, and meeting the demands on carrying people and objects in an inclined building.
