PLUNGER GUIDE FOR A TELESCOPIC JACK IN A HYDRAULIC ELEVATOR

摘要

A plunger guide for a telescopic jack in a hydraulic elevator inlcudes a crenelated guide rail with a top surface, two opposing side surfaces which a re 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./SDOAB
