Abstract
Official abstract text for this publication.
A system for connecting a gullwing to a catwalk comprising a gullwing pin movable in an indexer groove that enables a foot pad of the gullwing to remain stationary relative to the catwalk when the gullwing is raised or lowered.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of attaching a gullwing to a catwalk, comprising: coupling a pin to a knuckle of the gullwing; and inserting the pin into a slot formed in an indexer unit that is coupled to the catwalk to attach the gullwing to the catwalk, wherein the pin moves within the slot in a direction toward the catwalk when the gullwing is raised relative to the catwalk. 2. The method of claim 1 , wherein the pin moves in a substantially horizontal direction within the slot toward the catwalk when the gullwing is raised relative to the catwalk. 3. The method of claim 1 , wherein the knuckle is movable relative to the indexer unit when the pin moves within the slot formed in the indexer unit. 4. The method of claim 3 , wherein the pin is disposed through the knuckle such that portions of the pin extend from opposite sides of the knuckle, and wherein the portions of the pin are positioned within the slot formed in the indexer unit. 5. The method of claim 1 , wherein a foot pad coupled to the gullwing remains substantially stationary relative to the catwalk when the gullwing is raised or lowered. 6. The method of claim 5 , further comprising raising the gullwing relative to the catwalk by extending a rod from a hydraulic cylinder against the foot pad. 7. The method of claim 6 , further comprising supporting a section of pipe using an indexer pin of the indexer unit, wherein the section of pipe is transferred by the gullwing when the gullwing is raised relative to the catwalk.
