The present application provides a tractor assembly and an elevator. The tractor assembly includes: a traction sheave, having a traction means fitting surface and a first transmission surface on a peripheral surface thereof; a plurality of support wheels, configured to support the traction sheave, and each having a second transmission surface on a peripheral surface thereof; and support wheel bases, configured to support the support wheels through support shafts, wherein the first transmission surface of the traction sheave is in transmitting cooperation with the second transmission surfaces of the plurality of support wheels respectively. According to the tractor assembly and elevator of the present application, the support wheels are disposed to achieve the transmitting cooperation of the traction sheave during operation of the elevator and support the traction sheave, thus omitting the load and drive bearings required by a conventional traction sheave. Therefore, not only the weight of the unit is reduced, but also the reserved hollow part of the traction sheave increases the area of ventilation, thus improving the heat dissipation effect of the rotor winding of the traction unit. In addition, this structure is also easy to disassemble/assemble and maintain.
