The invention discloses an elevator brake component. The elevator brake component comprises a transition brake face and a final brake face. In the process from the elevator normal running state to thebrake state, the transition brake face is in contact with a guide rail so that an elevator is transited to the brake state from the normal running state. In the elevator brake state, the final brakeface is in contact with the guide rail so as to brake the elevator. The friction coefficient of the transition brake face is larger than that of the final brake face. By means of the elevator brake component, it can be guaranteed that brake positions are in place, and the original performance of a brake part can be kept. The invention further provides an elevator brake device.

    本发明公开了一种电梯制动部件,包括:过渡制动面,其在电梯正常运行状态到制动状态过程中与导轨接触并致使电梯从正常运行状态过渡至制动状态;最终制动面,其在电梯制动状态下与导轨相接触以使电梯制动;所述过渡制动面的摩擦系数大于所述最终制动面的摩擦系数。本发明的电梯制动部件能够既保证制动装置到位,又保持制动件原有的性能。本发明还公开了一种电梯制动装置。
