Step 6: Strength & Stability
The strength and security of the Vortex should be tested
prior to use. This may be achieved by applying a test load to
the system and checking that all components are correctly
performing their function.
The Vortex has been extensively tested for strength in a
controlled environment. The results of the testing prove that
the Vortex can be safely used to support personnel in a wide
variety of configurations. Extreme caution must be exercised
by the user if configurations other than those described
within this manual are used. Additional Vortex-specific
training from a qualified instructor is highly recommended.
Ways to maximize the strength and stability of the Vortex are:
- Minimize the height.
- Minimize the length of legs.
- Connect the Outer Leg coupler into the Gin Pole head so
the Inner Leg is toward the foot.
- Avoid placing an Inner Leg mid-span between two Outer
Legs.
- Connect to the center Gin Pole (orange) yoke when
using a Tripod configuration (See page 8).
- Connect to the vertical center connection point of the
A-Frame (blue) Head when using an A-Frame (See page
8).
- Connect opposing guys to the same point on the head
to reduce the twisting tendency on the head.
- Use appropriate material and methods for hobbles,
lashings and guys (as described in the "Securing the
feet" and "Securing the head" sections on page 18).
- Each pair of feet should be independently hobbled.
- Ensure acceptable guy and Applied Force Angles.
- Minimize transverse stresses on the legs by ensuring
leg forces are predominantly axial. Ensure mid-span leg
connections are loaded axially. Do not allow objects or
structures to contact the legs mid-span.
- Select anchors of appropriate strength.
- Carefully plan and select the most appropriate rigging
equipment and techniques.

SUPPORT STRUCTURE / SURFACE REQUIREMENTS
The strength requirement of the supporting structure
/ surface varies depending on the Mode of Use and
application.
ANCHOR FRAME:
The structure / surface selected must sustain a static load
equal to that specified for the application, in the direction
permitted by the system when in use.
DIRECTIONAL FRAME:
The load factor of the directional pulley must be considered
when determining the support strength requirement. The
structure / surface selected must sustain a static load equal
to that specified for the application multiplied by the load
factor, in the direction permitted by the system when in use.
Configurations
On the following pages (22-28) is a simple guide to the
most commonly used Vortex configurations. Each of the
following standard configurations has specific attributes,
rigging requirements and usage guidelines that should
be followed. Other, more complex configurations require
advanced rigging skills and expert evaluation prior to
being placed in service.
