ELEVATOR SYSTEM WITH A GUIDING STRUCTURE COMPRISING AT LEAST ONE GUIDE RAIL BRACKET
An elevator system includes at least one elevator car that is configured for traveling in a hoistway along a longitudinal direction (L) between a plurality of landings; at least one tension member for supporting and driving the at least one elevator car; and a guiding structure. The guiding structure comprises at least two guide rails provided in the hoistway for guiding the movement of elevator car and/or of a counterweight in the hoistway; and at least one guide rail bracket extending along a transverse direction between two of the at least two guide rails for the coupling two guide rails with each other. The at least one guide rail bracket includes a recess that allows the at least one tension member to pass the at least one guide rail bracket by extending through the recess.
ELEVATOR ARRANGEMENT EXHIBITING ECCENTRIC GUIDE RAILS AND AN ECCENTRIC DRIVE UNIT AS WELL AS USE OF AN ECCENTRICALLY ARRANGED DRIVE UNIT FOR SUCH ELEVATOR ARRANGEMENTS
The present disclosure relates to an elevator arrangement exhibiting at least one cabin and at least one drive unit, wherein the at least one cabin is coupled with the drive unit by traction member interacting with the drive unit in a drive zone, wherein the cabin is guided by cabin guide rails arranged eccentrically according to a horizontal direction/axis with respect to a lift shaft centre line; wherein the drive unit's drive zone is arranged eccentrically with respect to the lift shaft centre line, wherein the cabin guide rail's eccentricity is opposite the drive zone's eccentricity. The eccentricity of the drive zone is at least a predefined/predefinable factor of the eccentricity of the cabin guide rail(s). Such configuration also allows for favourable arrangement of both the cabin guide rail(s) and the drive unit in context with emergency stop situations.
