Abstract
A pipe handling system reduces the amount of physical effort required for an operator to transfer steel rotary drilling pipe sections from a storage location to and from a rotary drive unit. The system utilizes an indexing arm which removes or adds the pipe sections from the storage location, placing them in the correct position to be attached to or removed from the rotary drive unit. The index arm, unlike other systems, can remove individual pipe sections to and from the storage location directly to the rotary drive unit's centerline of drilling position. This reduces both the number of physical moves required to complete the task and the amount of weight being transferred. The indexing arm is able to lift a pipe section from the storage location and place it below the rotary drive unit's centerline, then lower away from it without additional movement of the rotary drive unit itself.
