Using a Yoke to carry or support heavy loads is nothing new. In terms of logistical equipment, I would guess that it is one of the oldest designs, in some form or another, to help humans carry more than they were originally designed to - and when it comes to helping humans carry more than they should, there's most certainly one department where that might be useful!
Whilst the very over-bosomed Faye has been allocated to test out this 'new' piece of support equipment, she can't help feel that it isn't really all that new. In fact, she recalls seeing a photo of her Great-Grandmother using something similar to carry two large milk pails on the family farm many, many years ago.
Of course, this contraption is a bit of a step up from the roughly carved peice of wood that her Great-Grandmother used. Instead, it's a rather advanced composite, that gives both strength and flexibility, helping to reduce excessive 'bounce' and also prevent sudden tugs or jolts on the straps that are connected to the yoke directly. You'll also notice the additional 'Control Handles', also known as 'Parade Straps' (explained in Lori Needs a Lift) that are there both to offer additional support, and also allow extra control and guidance of such a large, cumbersome load.
The yoke itself is very much an early prototype at this point, althought it does have some creature comforts, such as padding around the upper shoulders and neck, and dedicated grips on the parade straps. There's also some adjustability to allow for some variety of size and volume. Faye here is, well, probably at the limit of the yokes capacity, and her own. However, at her size, it is unlikely that she would be able to stand or even lift her enormous bust off of the ground in just a bra - so the yoke definitely gives some advantage in increasing the capacity and mobility of the wearer, even of progress is often slow and cumbersome. On the down side, placing much of the load onto the upper-back and neck means that it can quickly become quite uncomfortable or even painful, so for now, it is trialled for short periods only.
Not to worry though, I'm sure much more development will be done, by both the engineers, and Faye, too..
