METHOD AND APPARATUS FOR HANDLING LIFT SUBS AND OTHER OBJECTS |
| 摘要 |
A lift sub handling assembly for gripping, handling and maneuvering a lift sub or other tubular member. A yoke member defining a slot is rotatably attached to a lifting frame which, in turn, can be suspended from a hoist, winch or other lifting device. A gate can be selectively opened to a lift sub or other tubular member to be received within the slot, and thereafter closed to secure the lift sub or other tubular member in place. A motor can selectively rotate the yoke member relative to the lifting frame, thereby changing orientation of a lift sub or other tubular member held within the slot. |
