The Vortex is used to support ropes, pulleys and other rope
rigging equipment. The three most common functions are to:
A
. Support ropes directly from the head of the frame
(fig.
1a
).
B
. Support ropes from a leg-mounted winch, through a
directional pulley on the head of the frame (fig.
1b
).
C
. Support a directional pulley or pulley system on the
head of the frame (fig.
1c
).
For correct rigging, the user must know both the
direction
and
magnitude
of the force acting on the frame. For this pur-
pose we have designated two primary Modes of Use:
Anchor Frame
– The rope supporting the load is termi-
nated (anchored) to the Vortex (figures
1a
and
1b
).
Directional Frame
– The rope is not terminated to the
Vortex but rather is redirected through a pulley which
is supported by the Vortex (fig.
1c
).
Step 1: Mode of Use
Knowing the Mode of Use will assist the user in determining
the applied force (force acting on the frame).
Anchor frame
•
The magnitude of the applied force will be equiva-
lent to the mass of the load.
•
The direction of the applied force will be along the
load line towards the load from the last point of con-
tact the load line has with the frame.
Directional frame
•
The magnitude of the applied force will be equiva-
lent to the mass of the load multiplied by the load
factor of the directional pulley / pulley system (resul-
tant force).
•
The direction of the applied force will be the bisect
of the lines running into and out of the directional
pulley /pulley system (resultant force).
Step 2: Identify the Applied Force
