A method determines a status of at least one component of an elevator system, wherein the elevator system includes a suspension apparatus having at least one traction member. The at least one traction member is surrounded by a non-metallic cladding, wherein the suspension apparatus is guided via a drive sheave with a metallic traction surface. The method includes the steps of: identifying at least one parameter based on an electrostatic effect which occurs due to friction of the non-metallic cladding on the traction sheave with the metallic traction surface; and determining a status of the at least one component on the basis of the identified parameter.

An elevator includes a control system for monitoring the load of a car, which control system is adapted to prevent the normal starting of the elevator, optionally also including relevelling, when there is an overload in the car. The elevator includes at least one position measuring device, speed measuring device and/or movement measuring device in order to determine the movement and/or position of the car, and the control system of the elevator is adapted to remove the prevention of normal starting when at least one said position measuring device, speed measuring device and/or movement measuring device detects that the car moved or is moving upwards in the elevator shaft. In the method, the control system of the elevator is used to determine the load situation of the car, including both the steps to prevent the normal starting of the elevator, optionally also including relevelling, when there is an overload in the car and to open some of the machinery brakes and to keep the remaining machinery brakes closed in order to determine the load situation.

A single-cable drum-type conveying installation with a cable drum driven by a winch drive, includes a cable-monitoring device, a conveying device, which hangs freely on a conveying cable, and an intermediate harness connecting the conveying cable to the conveying device. The cable-monitoring device includes a load-measuring pin, as a constituent part of the intermediate harness, and also a transmission path along which a measuring signal received from the load-measuring pin is transmitted to an evaluation device. The evaluation device is designed for evaluating the measuring signal such that, in the case of the measuring signal jumping by an extent which exceeds a certain amount, a malfunction is detected.
