Summary:A force limiting rope brake includes a pair of rigid first and second side-plates in parallel overlaid array sandwiching therebetween a pivotally mounted pulley. The pulley pivots about a pivot axis extending orthogonally between first and second side-plates. A pair of rigid wedges are rigidly mounted between the first and second side-plates on opposite lateral sides of the pulley. The first and second wedges and the pulley when in the first and second positions define, respectively, first and second gaps, the first and second gaps identical in size and sized so that rope segments journalled through the first and second gaps are compressed in either the first or second gaps when the pulley is rotated into either the first or second positions respectively.
