<p>A roping device for operating on a rope includes a first body portion (11) providing an attachment means (34) at one end, the body portion (11) including a first plate (18) having a front face and a reverse face and a second plate (20) having a front face and a reverse face. The plates (18, 20) are oriented in different planes defining an acute angle between the intersection of those planes. A first rotatable sheave (12) is mounted on the front face of the second plate (20) rotatable about an axis which is substantially perpendicular to the second plate. The first sheave (12) has a groove defining a generally semi-circular rope guide path having a first end and a second end. The first end of the guide path opens onto the front face of the first plate, and the second end of the guide path opens onto the reverse face of the first plate (18). The front face of the first plate defines a generally straight guide path in the form of a channel 21 along which the rope passes prior to the generally semi-circular guide path. A braking means (24) is mounted on the front face of the first plate (18).</p> |
