FIELD: transport.
SUBSTANCE: lifting machine comprises motor to drive lifting machine shaft 14. Machine brake 20 applies braking force to disc 22 coupled with machine shaft 14 to decelerate or stop said shaft. In compliance with one version, brake 20 actuates shifting element 38 to apply shifting pressure to tong-type braking mechanism to apply braking force to disc 22. Brake drive 48 with deformable material displaces to counteract shifting pressure to control adhesion between braking mechanism 32 and disc 22. Controller varies braking force applied to disc 22 to control input force on said deformable material. Position of braking element relative to rotary part is defined using material input signal magnitude.
EFFECT: higher operating performances.
