The invention discloses a polyurethane vibration absorption structure of a heavy freight elevator tractor bearing frame. The polyurethane vibration absorption structure comprises a bearing beam and a bearing frame used for the mounting of a tractor, wherein the bearing beam and the bearing frame are in threaded fastening, a polyurethane vibration absorption rubber is padded in the threaded fastening part between the bearing beam and the bearing frame, and clamping plates are clamped on the two sides of the polyurethane vibration absorption rubber. According to the invention, since the polyurethane vibration absorption rubber is padded in the threaded fastening part between the bearing beam and the bearing frame, a flexible vibration reduction effect is played, impacts caused by resonance phenomenon of the tractor to a lift car can be reduced, the noise of the lift car is lowered, the comfort of passengers for taking the elevator is improved, and the advantages of excellent resilience, excellent wear-resisting property, long service life and high pressure bearing capability of the polyurethane vibration absorption rubber can be applied.
