The invention relates to mechanical equipment of elevator mounting, in particular to a tractor rack which can increase traction force and is high safety coefficient. The tractor rack comprises two parallel bearing beams. A support is arranged on the bearing beams and provided with a mounting seat for mounting of a traction wheel. A guide wheel is further arranged on the support, and damping mechanisms are arranged between the bearing beams and the support. Connecting blocks are arranged on the support, the guide wheel is arranged on the connecting blocks and located between the two bearing beams, and the axis of the guide wheel and the bottom faces of the bearing beams are coplanar. According to the tractor rack, the contact length of a traction steel wire rope and the traction wheel can be increased; under the gravity action of a car, the larger the friction force of the traction steel wire rope and the traction wheel is, the larger the traction force is, power output by a tractor can be reduced, and labor can be saved; and the larger the friction force of the traction steel wire rope and the traction wheel is, the larger a wrap angle is, the traction steel wire rope cannot be separated from a groove of the traction wheel, the slipping phenomenon cannot occur, and the safety coefficient is higher.
