Abstract
A rope termination (10) for a rope (19) having a plurality of sub-ropes (21 -32), the rope termination including a connection device having a load pin (12)wherein each of the plurality of sub-ropes (21 -32) is spliced into itself to form a looped end, wherein the looped ends are arranged on the load pin and each of the plurality of sub-ropes (21 -32) is of equal length. The connection device further includes a connector (34) for a rope connection assembly whereby tension is equally transferred between the load pin and each of the plurality of sub-ropes.
Claims23
A rope connection comprising:
- a rope termination of a rope having a longitudinal axis and a plurality of sub-ropes, said rope termination comprising a termination member having proximal and distal ends and a plurality of load pins formed in a closed annulus around said longitudinal axis, each of said plurality of sub-ropes being spliced into itself to form a looped end arranged around said load pins and each of said plurality of sub-ropes being of equal length, wherein said termination member further comprises at least two tabs interconnecting said load pins, which said tabs extend radially outwardly from said longitudinal axis such that a circular cylindrical surface concentric with said longitudinal axis and intersecting said tabs entirely surrounds said load pins and said sub-ropes disposed around said load pins, said rope extending from said proximal end of the termination member;
- and
- a connector for connection with said tabs;
- whereby tension in the rope is equally transferred to said connector through said tabs and equally divided between said load pins and each of said plurality of sub-ropes.
A rope termination of a rope having a longitudinal axis and a plurality of sub-ropes, said rope termination comprising a plurality of load pins formed in a closed loop around said longitudinal axis and each of said plurality of sub-ropes being spliced into itself to form a looped end arranged around said load pins, each of said plurality of sub-ropes being of equal length, wherein said load pins each have a section in a radial plane that comprises a circular end of radius greater than or equal to 1.5 times the radius of the sub-rope and sides that taper by an amount equal to or less than the angle subtended by said looped end of the sub-rope at said splice when arranged around said load pin, such that each said sub-rope is without a deflection between said circular end of the load pin and the splice. splice when arranged around said load pin, such that each said sub-rope is without a deflection between said circular end of the load pin and the splice.
A rope connection comprising:
- a rope termination of a rope having a longitudinal axis and a plurality of sub-ropes, said rope termination comprising a termination member having proximal and distal ends and three load pins arranged in a triangular formation around said longitudinal axis, each of said plurality of sub-ropes being spliced into itself to form a looped end arranged around said load pins and each of said plurality of sub-ropes being of equal length, wherein said termination member further comprises three tabs interconnecting said load pins, each tab projecting outwardly from each vertex of said triangular formation such that a circular cylindrical surface concentric with said longitudinal axis and intersecting said tabs entirely surrounds said load pins and said sub-ropes disposed around said load pins, said rope extending from said proximal end of the termination member;
- and
- a connector for connection with said tabs;
- whereby tension in the rope is equally transferred to said connector through said three tabs and equally divided between said three load pins and each of said plurality of sub-ropes.
