Methods and systems for in-pocket tendon shearing

A cable support apparatus operable to removably couple a shearing apparatus to a cable, the cable support apparatus comprising:

• a central spring pin;
• a first pivot pin;
• a first pivoting cable support member configured to pivot about the first pivot pin and comprising a first cable notch;
• a first spring coupled to the central spring pin and the first pivoting cable support member;
• a second pivot pin;
• a second pivoting cable support member configured to pivot about the second pivot pin and comprising a second cable notch;
• and
• a second spring coupled to the central spring pin and the second pivoting cable support member;
• wherein the first and second springs are configured to hold the first and second pivoting cable support members in a closed position;
• and
• when the first and second pivoting cable support members are in the closed position, the first and second cable notches collectively form a cable aperture that is shaped to at least partially surround the cable, thereby securing the shearing apparatus to the cable.

A method of shearing a cable in a concrete support system, the method comprising:

• attaching a shearing apparatus to a cable using a cable support of the shearing apparatus, the shearing apparatus comprising:
• a central spring pin;
• a first pivot pin;
• a first pivoting cable support member configured to pivot about the first pivot pin and comprising a first cable notch;
• a first spring coupled to the central spring pin and the first pivoting cable support member;
• a second pivot pin;
• a second pivoting cable support member configured to pivot about the second pivot pin and comprising a second cable notch;
• and
• a second spring coupled to the central spring pin and the second pivoting cable support member;
• wherein the first and second springs are configured to hold the first and second pivoting cable support members in a closed position;
• and
• when the first and second pivoting cable support members are in the closed position, the first and second cable notches collectively form a cable aperture that is shaped to at least partially surround the cable, thereby securing the shearing apparatus to the cable;
• and
• severing the cable by applying torque to the shearing apparatus via a torque generator.
