Both suspension frames are designed to fly an array of up to16 W8L
enclosures with a 7:1 safety factor in a vertical hang.
The table below shows the typical number of cabinets that can be flown
using 1 and 2 ton motors with the large suspension frame weighing 130Kg
(286lbs). These calculations do not necessarily allow for the points to act as
a cable pick.
Single Point (Bridle to crane hook)
1 x 1 ton Motor (up to 6 cabinets)
1 x 2 ton Motor (6 to 12 cabinets max) 2 x 2 ton Motors* (8 to 16 cabinets)
*Note that the front to rear weight distribution becomes much more
critical when the array is tilted. For example, if the array is tilted far
enough so that all the load is borne by the rear point alone, then the
maximum number of cabinets permitted would revert to the figure for
a single point.
WARNING!
Careful calculations must always be made to ensure that all
components are used well within their rated safe working load before
the array is lifted. Never exceed the maximum load ratings marked on
motors or suspension frames. Always raise and lower the load slowly
and avoid rapid changes in load distribution that could result in a
sudden jolt to the suspension components.

W8L Enclosure Rigging Hardware
The W8L enclosure has steel rigging hardware at the front and rear of the
enclosure. At either side of the front of the enclosure, a sliding tongue is
stored within the front rigging assembly. Removal of a quick release pin
allows the tongue to drop down into the front rigging assembly of the
enclosure below, where it is secured using the same quick release pin.
With this arrangement, the fronts of adjacent enclosures are hinged and
securely locked together with only 5mm spacing between them.
At either side of the rear of the enclosure, there is a channel housing a
steel splay arm, used to set the splay angle between enclosures. In transit,
the splay arm is held in place by a spring loaded catch. When released
from its transit position swing the arm up into the channel of the enclosure
above and fix at the required splay angle by the insertion of a quick release
pin. This pin is stored at the rear of the enclosure during transit.
