Abstract (en)

[origin: WO2016193631A1] The invention relates to a method for monitoring elevator equipment. Said elevator equipment includes a car and/or counterweight, two pulleys that are to be installed on the respective ends of an elevator shaft, a linear element passing through the pulleys and on which the car and/or counterweight is mounted, and a drive motor for moving said linear element. The elevator equipment is arranged so that said at least one linear element forms a closed loop with the pulleys and the car and/or counterweight mounted on the linear element. The method includes: (a) receiving (204) a measured value of a parameter representing a drive torque (C'') applied by the motor, (b) estimating (202, 205) at least one value (Q) of a parameter related to the elevator equipment on the basis of the value received in step (a) of the parameter representing the drive torque, and (c) transmitting a signal, produced on the basis of the value estimated in step (b), to a user interface or device for controlling the elevator equipment.
