Step 5: Guy Angles
The Guy Angle and the Applied Force Angle are the key
factors used to determine the forces acting on the guys and
the Vortex frame. These forces can be precisely calculated;
however, to allow the user to quickly ensure that the forces
are within and acceptable range, the following rules-of-
thumb should be used.
1. Guy Angle
should not be
less than 30°,
ideally not less
than 45°.
45°
2. Guy Angle not
less than the

The angle formed between the applied force
(AZTEK pulley system) and the Gin Pole is referred
to as the Applied Force Angle. The Guy Angle
directly opposes the Applied Force Angle and is
the angle formed between the Gin Pole and the
guyline.

Whenever possible, the Guy Angle should be kept above 45°.
In some situations this may not be possible. However, under
no circumstance should the Guy Angle be less than 30°. If
these rules are met, the magnitude of the force on the guy
will not exceed that of the applied force.
In some configurations there may be multiple guys support-
ing the Vortex. It is essential that the user properly identify
which guyline will resist the Tendency of Movement of the
Vortex. It is this guyline (or Guy Plane if multiple guylines are
used) that must meet the Guy Angle Rules described in this
section.
The positioning of components described in this section may
be relative to the angle of a Guy Plane, rather than to a single
guy, and to a Frame Plane, than to a single leg of the frame
(see fig. 5c & 5d).
