A hoisting machine (2') comprises an axial flux motor comprising a rotor (31) having rope grooves (6) and arranged in rotor compartment (58) between a body part (35) and a protection plate (28), and a stator (32) arranged against the rotor (31) in such a manner that the rotor (31) is separated by the stator (32) by an air gap (33). The hoisting machine (2') further comprises a first cover plate (51) and a second cover plate (53), arranged at opposite sides of the hoisting machine (2'), and both being equipped with a damper (59). The tightness between the first cover plate (51) and the second cover plate (53) is adjustable. The invention further provides improvement in vibration damping of the hoisting machine and in an elevator assembly.
