The present invention relates to a progressive elevator safety brake, in particular for use in an elevator system, comprising a safety block substantially made of a polymer material or polymer matrix composite. The safety block includes an elongated channel and a cavity. The safety brake includes a first brake member received in the cavity, the first brake member including a body and a first brake surface. The safety brake includes a second braking component including a second braking surface. A first brake member is disposed on one side of the elongated channel and a second brake member is disposed on the other side of the elongated channel. The first brake member is arranged to move between a first position and a second position. The first brake surface and the second brake surface define a first separation distance when the first brake member is in the first position, and the first brake surface and the second brake surface define a second separation distance when the first brake member is in the second position, the second separation distance being less than the first separation distance.
本发明涉及一种渐进式电梯安全制动器,具体地用于在电梯系统中使用的电梯安全制动器,其包括:安全块,其基本上由聚合物材料或聚合物基复合材料制成。安全块包括细长通道和空腔。安全制动器包括容纳在空腔中的第一制动部件,其包括本体和第一制动表面。安全制动器包括第二制动部件,其包括第二制动表面。第一制动部件布置在细长通道的一侧上,第二制动部件布置在细长通道的另一侧上。第一制动部件布置成在第一位置和第二位置之间移动。当第一制动部件处于第一位置时,第一制动表面和第二制动表面限定第一分离距离,当第一制动部件处于第二位置时,第一制动表面和第二制动表面限定第二分离距离,第二分离距离小于第一分离距离。
