Abstract: A method for providing well access in an elevator well having at least one elevator car moveable in the elevator well, includes the following steps: a well access operating mode of the elevator is activated, in which well access operating mode the elevator car will not respond to any landing calls, group controller commands or to any other remote commands, upon activation of the well access operating mode the car is controlled to travel a set distance up or down, the car is controlled to stop at said distance for a given time, the elevator will automatically exit the well access operating mode and return back to service if within the given time no well entrance, e.g. landing door, is opened. After non authorized activation of the well access operating mode, the elevator is automatically returned to service, which reduces the danger of off-service times of the elevator based on misuse of activation signals.

Abstract: An elevator includes a car, a counterweight, and a hoisting member connecting the car with the counterweight over a traction sheave. A free fall protection system includes a free fall protection controller, a free fall protection member connecting the car with the counterweight over the traction sheave or over a separate free fall sheave. The car and the counterweight are supported by the hoisting member in normal operation and by the free fall protection member only in a situation in which the hoisting member support fails. At least one free fall protection brake is arranged to stop the movement of the free fall protection member and thereby also the movement of the car and/or the counterweight, when being activated by the free fall protection controller.
