    摘要: A system with an apparatus that moves on wheels along a track defined by rails, and comprises two opposite sides carried by two or more wheels. The apparatus comprises detectors, at least one detector in either side of the apparatus in a known spatial connection with a wheel for generating to the control unit a signal that represents a measured lateral distance of a specific part of the wheel from a rail. Signals received from detectors are associated with position data that represents a specific position along the track where the lateral distance of the specific part of the wheel from the rail was measured. Signals received from detectors in spatial connection with wheels in opposite sides of the apparatus are used to generate an indication that represents temporal dimensional compatibility of the apparatus and the track. An effective tool for advanced monitoring interoperability of the apparatus and the track.

    摘要: A method according to the invention of controlling a rotation speed of a motor of a speed-controllable hoist drive comprises receiving a lift speed instruction (ώ'm )\ forming a final speed instruction (ώm ) by using initial information con- taining the lift speed instruction (ώ'm ); and using the final speed instruction (ώm ) as a speed instruction for the rotation speed of the motor of the speed- controllable hoist drive. The method further comprises monitoring a position derivative of an actual value of a cable force (dF/dz). The initial information for forming the final speed instruction (ώm ) comprises the position derivative of the actual value of the cable force (dF/dz).
