Fuse assembly having inline trigger for controlled failure and rope systems containing the same

A fuse assembly, comprising:

• a trigger, said trigger having a trigger rope segment and at least one trigger end, said at least one trigger end transitioning from said trigger rope segment to define a connection point for said fuse assembly, said trigger having a predetermined failure point;
• a catch separate from said trigger but working cooperatively therewith, said catch having a failure strength;
• and,
• wherein said trigger is separate from said catch.

A fuse assembly, comprising:

• a catch having at least one catch end, said at least one catch end defining a connection point for said fuse assembly, said catch having a failure strength;
• a trigger, said trigger having a predetermined failure point, said trigger being separate from said catch and external thereto working cooperatively therewith;
• and,
• a hold component, said hold component having a hold strength, said hold strength greater than both said failure strength and said predetermined failure strength, said hold component having a length greater than both said catch and said trigger such that said hold component is of unequal tension to said catch and said trigger, and wherein upon stretching or failure of both said trigger and said catch, said hold component maintains continuity of said fuse assembly.

A rope system comprising:

• a mainline;
• a terminal rope;
• a fuse assembly, said fuse assembly further comprising:
• a catch having a central portion and at least one catch end, said at least one catch end transitioning from said central portion, said at least one catch end defining a connection point for said fuse assembly, said catch having a failure strength;
• a trigger, said trigger having a predetermined failure point;
• wherein said fuse assembly is connected in series with, and intermediate, said mainline and said terminal rope.
