Array where at least every second column is supported
To create an array of multiple KNV Dots suspended from a rigging truss using GLP Half-
Slide Connectors where every second column in the array and the columns at the left-
and right-hand edges are independently supported:
See Figure 16 on page 31. For both columns at the outside of the array and for at
least every second column inside the array, obtain either:
a KNV Rigging Clamp 13-55/45/15, a KNV 5/8" Spigot and a GLP Half-Slide
•
Connector, or
a Half-Coupler Rigging Clamp, a GLP Half-Slide Connector and a high-tensile
•
screw or bolt to fasten the Half-Slide Connector to the Rigging clamp. All these
items must be capable of safely supporting the total weight of the column.
• Obtain a safety cable for each column in the array. Each safety cable must be
approved for the total load that it will secure.
Fasten the first two KNV Dots into GLP Half-Slide Connectors and rigging clamps
following the instructions in 'Flying a column of KNV Dots using a Half-Slide
Connector' on page 26. Hang the rigging clamps loosely on the truss. If you are
going to install an unsupported column between two supported columns, add a
third KNV Dot between the first two Dots and fasten the three Dots together with
GLP Slide Connectors as described in 'Fastening KNV Dots together' on page 22.
Fasten the rigging clamps securely to the truss and secure each of the three Dots
with a safety cable as described in 'Securing with a safety cable' on page 19.
Continue adding KNV Dots horizontally to the top row as described above until you
reach the desired width of the array. At least every second Dot must be supported,
and the Dots at both ends of the top row must be supported. Every Dot must be
secured with a safety cable as described in 'Securing with a safety cable' on page
19.
Add KNV Dots underneath the top row. Do not allow any column of Dots to exceed
the vertical limit of maximum of five (5) Dots high for an array where every second
column is supported. Each time you add a Dot, fasten it to the Dots on all sides
using GLP Slide Connectors as described in 'Fastening KNV Dots together' on page
22.
Fasten the bottom of the array to secure anchoring points so that no point in the
array can be pushed or pulled sideways. When immobilizing the bottom of the
array in this way, do not increase the load on rigging hardware by applying
downwards tension to the array.
