A rod linkage extension (43) connects a crank rod linkage (40) to an temporarily activatable brake release device (26) and an auxiliary drive device (28) in the elevator shaft upper end. The vertically effective length of the extension corresponds to the distance between floors of adjacent building stations (12.1-12.4). The extension has two or more extension elements (42,44). An Independent claim is also included for an elevator installation. |
