Method for determining traction capacity of lift system in process monitoring system, involves measuring difference between rope force and maximum load removal force at part of driving rope, and generating test statement

摘要

The method involves fixing a mass (3) i.e. lift car, according to measurement of rope force (S1), and determining tangential force of a traction sheave (2) based on the rope force and a parameter of a lift system. A maximum load removal force is determined, and brought into a part (5.1) of a driving rope (5) of the lift system. A difference between the rope force and load removal force is measured at the part of the rope, and a test statement is generated. Oscillation produced by force in the part of the rope is detected. An independent claim is also included for a process monitoring system comprising a lift system.
