STRENGTH RATINGS TABLE
As tested internally by manufacturer
Note: the working load limit (WLL) is the maximum allowed Applied Force acting on the Vortex. Be
aware the Applied Force is often significantly greater than the mass of the payload.

The table above details the assembly requirements to achieve
the listed Minimum Breaking Strength (MBS). The data contained
in this table is based on tests conducted within a controlled
environment using specific test conditions. The listed MBS
represents the force, above which, the system yielded and no
longer supported the load.
The listed Working Load Limit (WLL) has been calculated from the
MBS using a design factor of 4:1. The WLL refers to the applied force
(magnitude of force applied to the frame) and not necessarily the
mass of the load. Be aware that in some cases the applied force may
be greater than the mass of the load. Refer to Page 15 for further
information on identifying the Applied Force.
The user is responsible for determining if the configuration is suitable for
the application based on function, strength and security. The user must
decide if the rated strength is sufficient based on the specific situation
and environment, or if an additional margin of safety should be added.
ASSEMBLY REQUIREMENTS DEFINED
The example graphic to the right (See Fig. 1), shows a section of legs
connected to the A-Frame Head at the top, and a Raptor Foot at the
bottom. This example identifies the Outer Legs, Inner Leg, and the
number of Exposed Holes along the Inner Leg, as referenced in the
Strength Ratings Table.
To achieve the MBS & WLL shown in the left column above,
construct the Vortex configuration as identified in the
Strength Ratings Table pertaining to:
– Number of Outer Legs.
– Exposed Holes along Inner Legs.
– Height to Connection Point.
*Table represents user information based on
manufacturer's internal tests only.
