Abstract:
1. A pipe handling catwalk comprising: a deck including an upper surface, a first end, an opposite end and a tubular support surface on the upper surface, the tubular support surface being elongate and extending between the first end and the opposite end; a deck guide including a wall extending up from the deck upper surface and drivable along the tubular support surface of the deck; a ramp including a connected end, an upper end and a long axis extending from the connected end to the upper end, the connected end being mounted on the deck adjacent the first end and the ramp being positionable extending at an angle from the deck; a carrier including a support and an upper member, the upper member being elongate and including a front end, a rear end and a tubular retaining surface thereon extending along the carrier substantially in line with the tubular support surface of the deck, the upper member being axially slidable along the support substantially parallel, in plan view, with the long axis of the ramp between a first position with the front end adjacent the upper end of the ramp and a second position with the front end extending beyond the upper end of the ramp, and the support being pivotally connected by a hinge to the upper end of the ramp to remain on the ramp and being pivotally moveable about the hinge such that the rear end of the tubular retaining surface can be lifted away from the ramp to reduce the inclination of the tubular retaining surface relative to the angle of the ramp; and a carrier guide including an upstanding tubular engaging surface extending up from the tubular retaining surface and the carrier guide being drivable along the tubular retaining surface of the carrier.
