More Information
Summary:Disclosed is a pulley assembly in a roped access system including first and second plates and a sheave carried for rotation about an axis normal to the plates. An aperture passes through each plate parallel to the axis. The plates have a closed condition when the apertures are coaxial with one another and the plates are in contact near the apertures, forming a rope passage extending between the plates adjacent the sheave, having an upper part smaller than parts of the passage below that upper part. A roped access system includes a climbing rope passing through the rope passage and a tether connected to the climbing rope above the pulley assembly by a friction hitch and an aperture of the pulley assembly, the hitch. The hitch grips the rope upon downward force to the tether, releasing its grip upon upward force to the friction hitch by pulley assembly plates.
