An interchangeable elevator bail link system and method for changing elevator bail length and load carrying configurations during rig operations, wherein an upper bail section is provided comprising a connection for a link tilt system of a top drive or traveling block, and further comprising a connector for connecting to a corresponding connector located on one or more lower bail sections of differing tonnage capacities and lengths, wherein the upper bail section connector and lower bail section connector comprise male and female profiles of corresponding size, shape and location, so that when the connector of the lower bail section is aligned in nonparallel relation to the connector of the upper bail section, which is attached to a link tilt system, movement of the top drive or traveling block in an upwards direction will cause the lower bail section to rotate to a position parallel with the upper bail section. |
