Arizona Vortex Basic Configurations Overview

Written By: Lance Piatt

What is an Anchor Frame vs Directional Frame?

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.

The Equal-Leg Tripod shown is a Directional Frame, as the frame supports a pulley system and the haul line is
not terminated onto the frame. The use of independent hobbles alone is normally considered acceptable to secure the feet in this configuration.

In this case, the hobbles form a triangle between the feet. Ideally the load should be suspended in the center of the triangle. As the load is moved away from the center of the triangle the Tripod will have a tendency to topple.
Care must be taken to ensure that the load is kept in the center of the triangle. Additionally, keep the haul line
close to the load line to prevent the tendency of movement on the head of the frame.


EASEL-LEG TRIPOD
(with Leg-Mounted Winch)

The Easel-Leg Tripod shown is an Anchor Frame as the rope that supports the load is anchored to the frame via a leg-mounted winch. The use of hobbles alone is normally considered acceptable to secure the feet in this configuration. However, the action of cranking the winch may cause unwanted movement of the Easel-Leg.

As with the Equal-Leg Tripod, the hobbles form a triangle between the feet. Ideally the load should be suspended in the center of the triangle. As the load is moved toward the outside of the triangle, the Tripod will tend to topple.

Care must be taken to ensure the load is kept well within the triangle.

EASEL-LEG TRIPOD
(with Leg-Mounted Winch)

The Easel-Leg Tripod shown is an Anchor Frame as the rope that supports the load is anchored to the frame via a leg-mounted winch. The use of hobbles alone is not adequate to secure this configuration.

The tendency of movement of this frame is forward (over the edge), therefore the addition of a back guyline (or
other appropriate measures) is required to secure the frame.

The A-Frame configuration shown is a Directional Frame as the rope supporting the load is directed through a pulley on the head and is not anchored to the frame. The example shown would require a combination of hobbles and Raptor Feet inserted into crevices and guys to provide security and stability.

An A-Frame configuration requires guylines connected to anchors both to the front (near or over the edge) and to the back of the frame. Additional guylines may be needed to prevent the A-Frame from moving sideways if the load were to shift laterally.

 

SIDEWAYS A-FRAME

The Sideways A-Frame Bipod shown is a Directional Frame as the rope supporting the load is directed through a pulley on the head and is not anchored to the frame. The example shown would require a combination of hobbles, Raptor Feet inserted into a crevice, and guys to provide security and stability.

A Sideways A-Frame configuration requires guylines connected to anchors out to each side of the frame. For
this reason, this configuration is well suited to environments where anchors are not available at the edge.

 

The Gin Pole configuration shown is a Directional Frame as the rope supporting the load is directed through a pulley on the head and is not anchored to the frame. The example shown would require a combination of hobbles, Raptor feet inserted into a crevice, and guys to provide security and stability. A Gin Pole configuration requires a minimum of three (3) guys, ideally separated by 120°. This may prove to be difficult to achieve in some environments as suitable anchors may not be available. Additional guys may be necessary for these situations.
