WHAT HAPPENED:
The drilling crew had completed pulling the drill string out of the hole. The crew decided to service the rig while out of the hole. The derrickman went up to the crown to grease it. The driller saw the derrickman coming down the derrick ladder having finished the job of greasing the crown sheaves, so he instructed the floormen to grease the traveling blocks. One of the floormen put on the necessary safety equipment and attached himself to the man-rider winch line. The other floorman began lifting him to service the blocks.
