• No cross-bar jamming - rails glide on

smooth-running carriages

• Ideal where floor space and ceiling
height is restricted

• Floor left free of cables and lighting
stands

• Curved rail for comers and cycloramas

• Leave rigged and connected for next job

- speed tum-round

• Full range of accessories ensures

maximum flexibility

• Economical system with robust,

quality-built parts

Now at last there is a studio suspension system
for the smaller studio which is practical,
flexible and economical - adaptable to every
lighting requirement!
Strand LightRig is revolutionary in design, yet
simple in concept. Cross beams are
articulated and pivot on their bogie-type
carnages making them capable of moving to
any diagonal position . They are also free to
extend in either direction beyond the parallel
fixed track. Lurninaires can thus be placed in
any required position in the studio, reaching
even the most inaccessible comers . With the
use of pantographs, lights can also be set to
any height.

DESCRIPTION

A basic LightRig system
comprises two parallel light­weight fixed tracks equipped
with free-running double
carnages that support the
movable cross-beams . The
design of the
for cross-beam movement up
and down the track, or
diagonally across the track by
moving only one
cross beam may also be pulled
out to overhang beyond the
fixed track area .
Lurninaires are supported from
single 6 wheel
with a standard male spigot.
These make possible free
movement of lights along the
length of the cross beams. Lights
may also be suspended from the

carnages allows

carnage . A

carnages fitted

fixed track , if required, for
movement in two directions only.
To prevent uncontrolled fast
movement of equipment along
the tracks, the supporting
carnage s and lurninaire support
carnages incorporate pre-set
friction brakes.

SIMPLE TO INSTALL

The extrusion used for the fixed
and moving .tracks are identical,
and are supplied in standard
lengths of 2m, 3m and 4.5m.
There is also a radiused comer
rail for turning the track through
90°. A simple rail joining plate
means that fixed tracks of any
length can be installed .
The fixed track is secured
overhead and there is a choice
of mounting systems to suit all

types of structures.
The parallel spacing or pitch of
the track depends on studio
requirements with considera­tion also given to loading limits
when cross beams carrying
luminaires extend beyond
the track.

Double

carnage assemblies
and channel end stops are
fitted to the fixed overhead
track, and cross beams located
in the lower part of the
carnages. Cross beams, in tum,
are then equipped with 6 wheel
single

carnages appropriate to
the weight and number of
lurninaires required. End stops
are fitted to the cross beams to
retain the lurninaire
the end of the extrusion. Cross
beam

carnages have a

carnages at

standard 16mm
spigot for fixing luminaires
direct, or for mounting a
pantograph.
available to connect the
mounting spigot into a 29mm

(1 Ya") female socket to mount

larger lights directly onto
the

carnage .

Cable transfer runners are
located on the rail to move with
luminaires, keeping cable
looped along the track. The far
end of the light cables may be
connected with a plug-top to
the supply without need for
dedicated sockets, so lights

can be plugged in as required .
All LightRig components are
available separately so that
systems can be planned exactly
to suit individual needs.

OVERHEAD FIXING

The fixed track of the Strand
LightRig system must be
secured to a load-bearing
structure capable of carrying
the full weight of all track,
luminaires and accessories . To
calculate the weight of a system
use the component weights
table on the back page .

SYSTEM LOADING

The LightRig system itself is
robustly built with strong,
rigid extrusions , and
carriages with nylon wheels,
designed to
cross beams and luminaire /
pantograph loads with capacity
to spare . The maximum load is
determined by the track
suspension clips , with a 6:1
safety factor : the load on each
pair of suspension clips must
not exceed 50kg. Because the
cross beams can be bunched
together their loads must be
calculated when they are all

adjacent to one another.
Allowing a space between for
the size of the lights the load

(X)

Load

cany the weight of

LIGHTRIG LOADING LIMITS (6:1 SAFETY FACTOR)

MAXIMUM LOAD PER PAIR OF FIXING CLIPS = 50kg

LOAD/SPACING NOMOGRAM

can then be calculated and a
fixing provided at each point
where a 50kg load occurs.
However , when planning a
system layout, allowance must
be made for the extra loading
placed on carriages when
cross beams are extended
outside the fixed tracks . The
determining factors in
assessing these loading limits
are the spacing or pitch of the
fixed tracks , the amount of
overhang of the cross beam and
the load on the cross beam .

Using a straight edge on the

nomogram below, loading
limits (with a 6:1 safety factor)
can be calculated for
various situations .

Joining plates are not

recommended to extend
moving tracks . Ensure that
there is a fixing adjacent to
each rail joint and at spacings to
provide a support at every 50kg
loading along the rail.

EXAMPLE

With a pitch of 2.5m and a load
of 34kg the permitted overhang
would be (1.28m). Increasing
the overhang to 1.5m would
necessitate a minimum pitch of
3m ( or a reduced load) .

COMPONENTS

LIGHTRIG CURVED TRACK

The fixed track can be made to
turn through 90° by using the
special curved quadrant rail
which has a 2m radius . There is
a short straight section ofrail at
each end for joining to straight
track. In conjunction with the
curtain runners, curved rail may
be used for cyclorama cloths as
well as lighting.

LIGHTRIG PANTOGRAPH

Luminaires may be set to any
height below the fixed track by
fitting LightRig pantographs
which can be balanced to carry
any load from 0.25kg to 20kg .
Pantographs are equipped with

(%") female sockets for

16mm
direct mounting to LightRig
carriages .Forfurther
information ask for the Strand
LightRig Pantograph data sheet.
