2.2.1. Z5305 J Hoist connector chain

to the J Flying frame using the 3.25 t Shackles which is attached to the
J Load adapter. Its length of 53 cm (21") allows enough space for the
hang of most 2 t motor chain containers and avoids any influence to the
vertical balance of the array when suspended from a single pick point.
