<p>Methods and apparatus for handling blow-out preventer stacks (10) are disclosed. In one embodiment the handling system (20) includes a cart (30), a tilting frame (40), and a lifting frame (50). The stack (10) is attached to the lifting frame (50), which is slidingly supported by the tilting frame (40), which pivots relative to the cart (30). The cart (30) provides for positional adjustment of the stack (10) in a first horizontal direction, while positional adjustment in a second, perpendicular horizontal direction is provided by a lateral adjustment mechanism coupling the tilting frame (40) and the cart (30). The lifting frame (50) can be moved vertically relative to the cart (30) and also provides for rotational adjustment of the stack (10) about its central axis (12). <IMAGE></p> |
