The present invention concerns an emergency braking apparatus, comprising: a hoisting machinery brake (5) configured to engage against a rotating part of an elevator hoisting machinery (2) with a thrust force to apply braking torque to the elevator hoisting machinery (2); and a controller (6) connected to the hoisting machinery brake (5), the controller configured to cause the hoisting machinery brake (5) to engage against a rotating part of an elevator hoisting machinery (2) with a first thrust force (F1) during movement of an elevator car (1) and with a second thrust force (F2) during standstill of an elevator car (1). The first thrust force (F1) is lower than the second thrust force (F2).
