Abstract (en)
The invention relates to a hydraulic device for operating an elevator. The device comprises several single-acting cylinder sections (11, 12, 13) which are placed in series with each other. The cylinder sections are delivered to the place of installation separated from each other and are assembled in situ so as to form a single coherent elevator cylinder (10). The cylinder casing of a cylinder section is connected to the piston rod (14, 15, 16) of the adjacent cylinder section and the piston rod (14, 15, 16) has a channel through which the hydraulic oil is transferred from one cylinder section to a following section.
