Where the rope supporting the load is terminated onto the Vortex.
Where the rope supporting the load is not terminated onto the
Vortex, but rather is redirected through a pulley which is support-
ed by the Vortex.
Identify the Mode of Use.
Anchor Frame
Directional Frame
STEP 1
Identify the Applied Force
(Resultant).
STEP 2
Identify the Tendency of Movement.
STEP 3
Planned movements of the load.
Foreseeable unplanned movements of the load.
The head and the feet of the frame will tend to move if not
restrained.
Determine the magnitude and direction of the applied force:
Determine the Foot Securing
Requirements.
STEP 4a
The feet are secured to prevent any movement of the feet and
the frame.
Determine the Head Securing
Requirements.
STEP 4b
The head of the frame is typically secured using guys. The guys
give strength and rigidity to the frame.
Ensure Guy Angles are within limits.
STEP 5
Ensure guy / guy plane angles are:
- Not less than 30°.
- Not less than the applied force angle.
Test load the rigging to ensure frame
stability and security.
STEP 6
Ensure the rigging is tested by applying load to the system in a
safe situation. This test should be performed prior to supporting
personnel in a potentially hazardous area.
OR
IT IS VITAL THAT THE USER BE ABLE TO DETERMINE THE
DIRECTION AND THE MAGNITUDE OF THE FORCES ACT-
ING ON THE FRAME. THE FRAME NEEDS TO BE ASSEM-
BLED, HOBBLED, GUYED AND OPERATED TO RESIST ALL
FORCES WITHOUT ANY MOVEMENT OF THE FRAME AND
ASSOCIATED EQUIPMENT.
The steps below are a guide to successful Vortex setup and
operation. Never leave an unsecured Vortex unattended.
As in any rigging situation, one person should be in charge
of the set up and communication should be deliberate and
precise.

RECOMMENDATIONS FOR SETUP
CMC highly recommends training for the assembly portion
of the Vortex in a safe environment where all participants
can concentrate on the relevant tasks.
• Whenever possible, setup the Vortex away from the fall
hazard zone, then walk it to the edge. Support each
leg section until the unit is secured to prevent toppling
during set up.
• Take measures to prevent the Vortex from toppling over
the edge during setup and rigging. Attach the supplied
Tether Cord to the head of the assembly and config-
ure it as a belay while the Vortex is being moved and
secured into position.
