摘要
The invention relates to an arrangement for reducing vibration and noise caused by the hoisting machine of an elevator, said elevator comprising at least a hoisting machine (3) fitted on a mounting base (9,12), a drive sheave (4) connected to the hoisting machine (3), measuring means (7, 7') for the measurement of vibration and at least one functional element (6) for damping vibration. The rigidity of each functional element (6) is adapted to be varied on the basis of the measurement results obtained from the measuring means (7, 7').
