Abstract
A system includes a span block configured to couple with an extension from a top drive at a first end of the span block and configured to couple to a tubular at a second end of the span block. The system also includes a sensor block of the span block. The sensor block extends between the first end and the second end of the span block. Moreover, the sensor block is configured to provide an electronic indication of deformation of a portion of the sensor block in response to forces placed on the span block.
