The invention relates to a method for operating an elevator system. The method comprises receiving a request to drive an elevator car to a destination and generating an elevator car motion profile to serve the received request. The elevator car motion profile comprises at least the following motion parameters of the elevator car: acceleration, maximum speed, and deceleration. At least one of the maximum speed of the elevator car and the deceleration of the elevator car in the generated elevator car motion profile is defined on the basis of the destination. The invention relates also to a processing unit and an elevator system configured to perform the method at least partly.

A method for determining a degraded guide rail condition in an elevator system, a computer program product, and an elevator system are disclosed. The method includes obtaining first data including information about movement of an elevator component relative to a guide rail, and obtaining second data including information about movement of an elevator component. The method further includes comparing the first data and the second data to each other, and detecting, based on the comparison, a deviation fulfilling a deviation criterion. Still further, the method includes creating a signal indicating the degraded, such as misaligned, guide rail condition, such as of the first or the second guide rail.

The measurement arrangement for measuring the rotation speed of a component of an elevator, escalator, moving walkway or moving ramp comprises an inductive sensor that is arranged stationary in respect of a rotation axis of the component and adjacent to the component or a measurement part that is attached to the component in a rotationally fixed manner, and the component or the measurement part is configured as rotationally unsymmetrical about the rotation axis so that different angular positions of the component about the rotation axis generate different output signals in the inductive sensor.

A compensation guide, counterweight screen, traction elevator and method for guiding a compensation element are disclosed. The compensation guide includes a horizontally directed guide opening through which the compensation guide passes. The guide is mounted vertically movably to the counterweight screen.

An elevator includes an elevator shaft defined by surrounding walls and top and bottom end terminals; an elevator car vertically movable in the elevator shaft; elevator hoisting ropes coupled to the elevator car; an elevator hoisting machine including a traction sheave engaged with the elevator hoisting ropes; a traction monitor configured to determine traction of the hoisting machine; an electromechanical brake; a measuring apparatus adapted to provide speed data and position data of the elevator car; and a safety processor associated with the traction monitor and the measuring apparatus. The safety processor includes an ETLS threshold configured to decrease towards the top and/or bottom end terminal in accordance with the position of the elevator car. The ETSL threshold is adjusted on the basis of the traction of the hoisting machine. The safety processor is configured to determine an elevator car slowdown failure if the speed data meets or exceeds the ETSL threshold.

A ladder support bracket has a support shoulder for creating a support contact with a complementary backup. The bracket includes at least one jaw for joining the bracket to an upstanding rail of a ladder, the jaw having also a retainer mechanism by means of which the bracket&#x2014;when being attached to a rail of a ladder&#x2014;can be brought into a clamping position attaching the bracket unmovably to the rail and a release position holding the bracket in a swivel connection relative to the rail and/or movably along at least a section of such rail.
