Abstract
A plunger guide for a telescopic jack in a hydraulic elevator includes a crenelated guide rail with a top surface, two opposing side surfaces which are perpendicular to the top surface, and first and second flanged projections respectively projecting from the first and second side surfaces. The plunger guide also includes a support having a bracket and a lateral segment which connects the bracket to the plunger to be guided. The bracket includes a first set of bearings arranged for gliding on the top surface of the guide rail, a second set of bearings for gliding on both side surfaces of the guide rail, and a third set of bearings for gliding on a bottom surface of each of the first and second flanged projections which faces away from the top surface.
