ABSTRACT:
The problem of readily picking up a load using an aircraft without requiring ground personnel is solved by a coupling device (15) and a method of coupling a load using same. The coupling device includes a pivot member (17) pivotally mounted on the load having a disposition and configuration that is readily engaged by a hoist line (42) with an end or weight member (43) from above and guided into a retainer portion (22) so that as the hoist line is raised a connection is formed between the hoist line and the load. The pivot member serves as a load-bearing member during suspension. Upon deployment and relief of the weight of the load from the hoist line, the pivot member automatically returns to the starting position and the hoist line and end member are slid therefrom. Stringing apparatus inclusive of a support member (72) carrying front and rear coupling devices (15) and front and rear tower catches (75 and 76) is particularly effective in stringing line through the tower in accordance with a novel method of line stringing.
