A pulley is provided having a first plate and a second plate arranged adjacent to the first plate and connected to the first plate by an axle. An eccentrically mounted sheave is located between the first plate and the second plate and is adapted to freewheel in one direction only. The eccentrically mounted sheave is mounted eccentrically with respect to the axle. A fixed block is mounted between the first plate and the second plate and is adapted to fixedly lock a line between the fixed block and the eccentrically mounted sheave.

Self-camming pulley

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.

Force limiting rope brake

The gated rigging plate of the present invention includes a rigid member having first and second opposite ends, first and second rigid arms mounted to the member, and extending away from the first end of the member from opposite sides of the member adjacent the second end of the member. The first end of the rigid member has at least one anchor aperture formed therein. The first and second rigid arms have corresponding first and second distal ends. The first and second distal ends are inwardly turned in opposed facing relation so as to define corresponding opposed facing first and second rigging component receiving cavities between the first and second rigid arms and the second end of the member. The rigid plate may be pivotally mounted to the rigid arms.
