The invention discloses an elevator brake component which comprises a transition brake surface and a final brake surface, wherein the transition brake surface is in contact with a guide rail in the process from a normal operation state to a braking state of an elevator, and enables the elevator to be transited from the normal operation state to the braking state, and the final brake surface is in contact with the guide rail in the braking state of the elevator so as to brake the elevator; the friction coefficient of the transition brake surface is greater than that of the final brake surface; and hard particles are embedded in the transition brake face, and the surfaces of the hard particles have edges. The invention further discloses 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;所述过渡制动面上镶嵌硬质微粒,所述硬质微粒的表面存在棱边。本发明还公开了一种电梯制动装置。
