The invention provides a combined type polyurethane buffer for an elevator. According to the combined type polyurethane buffer, a metal spiral spring is placed in the polyurethane buffer, so that the polyurethane buffer conducts secondary buffering when bearing impact force, and therefore the polyurethane buffer has larger buffering force within small buffering stroke. The combined type polyurethane buffer for the elevator has the advantages that the combined type polyurethane buffer has smaller buffering stroke and larger buffering force under specific conditions, operation is safer, installation and maintenance are convenient, the service life is long, and production cost is low.
