摘要
An automatic load brake having a wear-induced locking mechanism for a hoist is disclosed. In various embodiments, the load brake includes a first shaft (376) defining an annular hollow portion and a radially outer surface; a second shaft (324) defining an engagement portion and a radially inner surface, the radially inner surface configured to engage the radially outer surface; a first reaction plate (304) coupled to the first shaft; a second reaction plate coupled to the second shaft; and a plurality of friction discs (308), with at least one of the plurality of friction discs coupled to a cup and disposed between the first reaction plate and the second reaction plate, the annular hollow portion of the first shaft being configured to lock to the engagement portion of the second shaft upon thinning of the plurality of friction discs.
