OK A-B.....You've got it. If you have a hoist (comprising pivot, jib and block & tackle) directly against a wall it's maximum arc of operation is 180 degrees (it can lift or drop to it's left, right and straight ahead)...however, put it at a 45 o angle between 2 walls and the arc of operation increases to 270o. This means in the warehouse case that barges can be unloaded/loaded directly to/from the warehouse or on to/off a cart (or even from a cart to the canalfront of the warehouse)

Clever lot, these Georgians.....now what about the height of the arch?
