A rope grip which comprises a shell (12) and a plate (16) defining a first gripping surface and a cylinder (20) defining a second gripping surface is disclosed. The two surfaces are in a facing spaced relationship and define a passage (30) for receiving a rope. The cylinder travels in an angular field of motion with respect to the plate which causes a rope of appropriate size to become jammed between the plate and the cylinder depending upon the position of the cylinder. An operating arm (18) is mechanically coupled to the cylinder in order to control its position and accordingly, the distance between the surfaces of the plate and the cylinder. |
