The present invention provides a tractor assembly and an elevator. The tractor assembly includes: a rack; multiple tractors; and multiple traction parts connected to an elevator car and an elevator counterweight respectively via the tractors; wherein the multiple tractors are mounted on the rack respectively, and are staggered along a horizontal direction; the vertical direction extends along an elevator hoistway, and the horizontal direction transects the elevator hoistway to extend. With such arrangement, on the one hand, arrangement of two tractors is implemented without making too many changes to an existing structure space; on the other hand, compared with a unit that uses a heavy load tractor, the product cost can be reduced significantly while achieving basically the same technical effect. In addition, the use of two tractors of a relatively small size also implements machine room-free or small machine room arrangement.
