Abstract
A casing racking module is located on a set-back platform at a forward edge of a drilling rig. The casing racking module has a casing frame forming rows for casing. Paddle assemblies are mounted on the casing frame. The paddle assemblies have a shaft, an arm pivotally located on the shaft, and a bumper pivotally located on the shaft. A rotary exit spring is located between the arm and the bumper. An arm stop limits rotation of the arm relative to the bumper. A rotary return spring is located between the bumper and the casing frame. A bumper stop aligns the bumper with the casing frame. An extendable gate opens from the end of each row.
