Abstract:
1. A pipe handling apparatus for handling sections of pipe to and from a derrick work floor, the apparatus comprising: a longitudinal base having a first longitudinal axis; a boom carrying member having a second longitudinal axis, said boom carrying member slidably mounted to the longitudinal base for telescoping axial movement along said first longitudinal axis; a longitudinal cavity within boom carrying member; member actuating means operable to move the boom carrying member axially relative to the longitudinal base along the first longitudinal axis; a boom supported by said boom carrying member, the boom having a proximal end proximal to the derrick work floor, a distal end distal from the derrick work floor, and a trough extending along the boom and adapted for receiving at least one section of pipe therein, the distal end of the boom being movably guided substantial horizontal along the longitudinal cavity of boom carrying member, so as to prevent substantial vertical movement of said distal end during operations; and boom actuating means operable to raise and lower the boom's proximal end; wherein when the boom carrying member is moved along the first longitudinal axis of the longitudinal base, said first longitudinal axis and said second longitudinal axis are substantially parallel.
