Abstract

1. Shock absorbing stop for a hydraulic hoist for use especially in hydraulic elevators formed as a synthetic material bushing (6) surrounding a piston (9) and interacting with a flange (9.2) of the piston (9) characterised thereby, that the synthetic material bushing is provided at its circumference with a plurality of outwardly open ringshaped grooves arranged at substantially the same spacing from one another ; in which stabilization rings (7) are inserted, having an outer diameter which is at least equal to the outer diameter of the synthetic material bushing (6) and an inner diameter which is smaller than the outer diameter of said synthetic material bushing (6).
