MANUAL
General INTERtruss
Read the manual carefully and completely and make sure you fully understand its contents
before attempting to install the truss modules.
Cautionary notes:
1. Never attempt to couple Interal Intertruss modules to similar modules or systems made by other manufacturers,
even if they appear to fit well. Other manufacturers may use different tolerances or different materials or
welding techniques, which may lead to reduced load-bearing performance and an unreliable connection.
2. Always subject the modules to a visual inspection before use.
The reasons for rejection are listed at the back of this manual. If you have any doubt about the dependability or
strength of a module, or part of a module, do not use it and mark it clearly in order to prevent accidental use.
3. Number or mark each truss module with a unique identifier – a numerical code, for example - as a system
documenting aid for inspections and/or tests.
4. Always use the load tables that are associated with the truss in question.
5. When using the trusses in hoisting or lifting structures, make sure the loading does not exceed 50% of the
values indicated in the tables.
6. Always draw up a hoisting or lifting plan beforehand when truss components or truss structures are to be
supported at more than two points.
7. Always support the trusses at the lattice joints.
8. Never subject the truss components or truss structures to excessive loads.
9. Avoid high intermittent loads and dynamic loads by ensuring that the trusses cannot flex up and down.
10. The specific static and dynamic loads must be calculated when building structures that do not use straight
trusses as specified by Interal. Both the constructor and the user must be aware of all relevant national, regional
or local legislation or regulations and ensure that these stress calculations are performed accordingly.
11. Never hoist people up on trusses, unless adequate safety precautions have been taken and the risk analysis
and stress calculations indicate that it is safe to do so.

Failing to follow instructions or disregarding warnings may lead to material damage, serious personal injury
or death.
The Intertruss can easily be identified by the two grooves on the coupling
sleeves and the Interal inspection/final check sticker which is applied to every
Intertruss truss module made by Interal after June 2003.
Application:
The Interal Intertruss has been developed to allow the construction of temporary
structures of varying types, sizes and shapes by assembling sets of truss
modules. The resulting truss structures can support a variety of types and
combinations of loads and are generally installed above persons on theatre
stages, TV studio floors, exhibition stands, dance floors, event stages etc.
These loads are mainly static and consist of light armatures, loudspeakers,
projection screens, decoration, displays, etc., etc.
If other forms of use are envisaged, it will be necessary to perform a new
risk assessment and evaluation analysis and recalculate stresses and
safety factors.

INTERTRUSS 32 / 33 / 34 SERIES

MANUAL
Description:
The Intertruss 32/33/34 is available in 3 models; as a flat truss (290 mm), a triangular truss (290 x 258 x 258 mm)
and as a square truss (290 x 290 mm).
The Intertruss 32/33/34 uses different tube sizes:
- In the case of the Intertruss 32/33/34, the longitudinal elements are made from round tube measuring
50 x 2 mm, and the lattice wall construction (verticals, diagonals and internal diagonals) is made from
20 x 2 mm round tube.
- In the case of the Intertruss 32D/33D/34(D/HD), the longitudinal elements are made from round tube
measuring 50 x 3 mm, and the lattice wall construction (verticals, diagonals and internal diagonals) is
made from 20 x 2 mm round tube.
See the summary on page 2 for more detailed information about dimensions,
weights and material grades.
The Intertruss 32/33/34 is supplied in straight lengths of 0.25m - 0.5m - 1 m
- 1.5m – 2m - 2.5 m, up to and including 5 m. In addition, various corner elements
are available for this type of truss; these include L, T, and X elements in
one plane, and also the same L, T and X variants with one or two attachment
points in the vertical plane.
The modules connect together using a system of removable biconical couplings
(photo), which generally are left in place on one side. The two halves of
the aluminium couplings are secured together by a steel truss pin.
The coupling sleeve is welded into the longitudinal elements of the lattice frame,
description
allowing the biconical couplings to connect to the coupling sleeves of each module.
This biconical coupling is fastened to the sleeves by steel truss pins that are
connection pieces
secured in place using a locking clip (R clip) or an M8 nyloc locknut.
The same coupling sleeves are used on all the corner elements (L, T and X
shaped, with or without extra vertical attachment points), and on arch elements
of varying lengths and curvatures that can be assembled to form circles of different sizes and designs.
INTERTRUSS 32 / 33 / 34 SERIES
Before use:
Before using the Intertruss 32/33/34, you must first determine the weight of the loads that will mounted to the truss
and whether these loads still fall within specification when the envisaged span sizes are considered.
You must also plan the installation sequence (the order in which various length pieces and/or corner elements will
be assembled) and the identify the position of each of the assemblies in the total structure.
You must also determine the combined loads exerted by the various types of equipment you plan to mount to the
structure and the locations of the support points.
The reactive force at each support point must be determined and compared with the permissible load of the supporting
structures (hoists, stands or vertical truss legs) and with the permissible shearing force that the Intertruss
32/33/34 can withstand.
PAGE
WARNING: Risk of failure of the L, T and X elements.
Corner elements made of standard truss material may fail due to a localised accumulation of
shearing and bending forces. When constructing corner elements in this way, you must halve
the permissible load for the straight trusses that connect to the corner element (minus 50%).
NB: Exceeding the maximum load capacity of any of the hoisting or lifting devices, or of the Intertruss construction
components, is forbidden. The hoisting or lifting plan can be drawn up in accordance with NERS-003.1 or an
equivalent directive or norm. You must have the information to hand for inspection and enforcement bodies.

This manual has been written with the greatest care and attention. However, Interal denies all liability for the consequences of
any errors or inconsistencies in the text. Interal reserves the right to modify products and manuals without prior notification.

MANUAL
Storage:
The Intertruss 32/33/34 should be stored in an area that is as free as possible of dust (preferably completely dust-free).
The truss components should be stored horizontally wherever possible. Measures must be taken to minimise the
accumulation of dirt or dust in the area of the couplings. Dust and dirt in the couplings make assembly difficult and
may cause damage to the coupling components.
Transportation:
The Interal Intertruss should be transported in the horizontal position. The truss parts should not be laid directly on
top of each other and should not come into contact with the wall or floor of the vehicle or sea container. They may
not come into direct contact with any other equipment that is transported at the same time. Any movement or vibration
in the loading area might cause parts to rub together, thereby damaging the aluminium. The use of transport
dollies is more efficient and reduces the risk of damage. In addition, a truss trolley increases efficiency when erecting
and dismantling the structure, and reduces the time taken to load the vehicle, etc. Obviously the total weight of
the load must be considered when pushing the load up or down vehicle loading
ramps and other inclines. Make sure enough helpers are present to control
the weight safely.
Interal T.C. offers a so-called truss carrier for transporting trusses. These
beams make it easier to stack trusses for transportation. The truss carrier is
suitable for both triangular and square 32/33/34 trusses.
Loose biconical couplings and the steel truss pins should preferably be
transported along with the tools required (copper-headed hammer) in a pin
storage box.
NB: Never transport trusses in the vertical position. This will cause the trusses
to rub against each other each time irregularities in the road surface cause
movement of the vehicle body, leading to wear and loss of strength. Also, if a
securing strap were to break, there would be a significant risk of injury by falling
trusses when unloading the vehicle or container.

WARNING: Risk of injury by falling trusses when loading and unloading.
Trusses stood vertically on the vehicle bed may easily topple over if the floor is not perfectly
level.

INTERTRUSS 32 / 33 / 34 SERIES

MANUAL
Erection:
It is recommended that the biconical couplings are left in place on one end of the truss modules. This significantly
increases the speed of erection, and reduces wear and tear caused by unnecessarily frequent disassembly and
reassembly. This also minimises the quantity of loose parts that need to accompany the trusses. Loose parts can
easily be forgotten or inadvertently exchanged with other similar-looking, but not identical parts.
It is preferable to work in teams of two.
1. Roll the dolly as close as possible to the area where erection is planned without creating an obstruction.
2. Loosen and remove the securing straps from the dolly and lift off the top truss part.
3. Visually inspect each truss module for signs of wear or damage. See page 5. Damaged modules or
modules with other defects should be laid out of the way and clearly marked as defective.
4. Lay the first truss module in the position shown on the drawing (truss plan).
5. Select the next truss module and connect it to the first.
6. Slide the second truss part with the protruding (male) couplings into the sleeves (female connection) of the
first part. The conical shape of the couplings make it easy to guide the protrusions into the sleeves.
7. To secure the truss parts to each other, one man should joggle the free end of the second module up and
down and from left to right while the other man inserts the truss pins into the locating holes and pushes
them home. A hammer is not generally necessary if the trusses have been properly maintained.
8. A copper-headed hammer can be used if the pins are difficult to seat. This is generally only required when
making connections in a different direction, e.g. L and T shaped corner pieces.
WARNING: Risk of damaging the truss.
Do not use a steel hammer as this might damage the truss pin and truss,
and avoid the use of unnecessary force when tapping in the truss pin; this may also lead to
damage.
Joggling the end up and down and from side to side is more effective.
9. Insert the securing clips (R clips) in the truss pin holes.
10. Repeat steps 4 to 7 until the required length has been assembled.
11. Rotate the assembled truss about its longitudinal axis by a half turn.
INTERTRUSS 32 / 33 / 34 SERIES
PAGE
WARNING: Risk of crushed feet or ankles
Alert the people close by that their feet could be crushed
if the full truss length were to roll out of position by approx. 60cm.
12. Insert the truss pins into the remaining locating holes and secure them in place with the R clips.
13. Turn the full truss length back to its original position.
WARNING: Risk of crushed feet or ankles
Alert the people close by that their feet could be crushed
if the full truss length were to roll out of position by approx. 60cm.
14. Mount any corner elements that are required to the assembled truss length.
15. If any lengths are to be connected to the corner elements: repeat steps 4 to 7.
16. Mount the assembled length to the corner element.

MANUAL
USE
1. Check all the joints for correct location of the truss pins and R clips.
2. Place the truss onto the support points (of stands or lifts) - or:
3. Use a flexible means of attachment to hoist the truss. The following are suitable: tubular polyester slings,
steel cable slings with a protective coating or so-called ‘Softsteels’, tubular webbing slings with a wirereinforced
core. If there is a risk of contact with spotlights or other hot objects in the direct vicinity, plastic
tubular slings should be equipped with a steel cable safety back-up.
WARNING: Risk of falling truss parts
Never use steel cables unless they are equipped with a protective mantle or coating that prevents
direct contact with the aluminium tubes. The steel cable is much harder and will ‘saw’
into the aluminium tubes.
4. Attach the truss to the hoisting or lifting equipment and lift it to the desired working height.
WARNING: Risk of overloading and falling trusses.
Always use hoisting or lifting equipment of a suitable lifting capacity and ensure that the
truss is lifted at a constant speed. Speed variations during lifting may generate high bending
moments in the trusses and could ultimately cause breakage.
5. Recheck all the joints for correct location of the truss pins and R clips.
6. Install the load(s) as shown on the drawing (lighting plan, decoration plan etc.)
7. Check that any loads supported on a hoisting/lifting structure made of 32/33/34 truss material do not exceed
half the value in the table. The load table for the 32/33/34 truss can be found on page 10.
In the case of fixed portal structures it is not necessary to halve the load values as stipulated by NPR 8020-10.
WARNING: Risk of breakage and falling trusses.
ALWAYS avoid overloading trusses.
8. Check the amount of deflection of the truss after the loads have been attached. The permissible deflection
is listed in the load table on page 10. Excessive deflection may indicate deformation in one or more
truss modules.
9. Raise the truss or truss structure to the desired ‘trim height’.
10. Note that the positions where the heavier loads are supported on the support points will move more slowly.
Where there are more than two support points, the truss may start to bend locally. Stop hoisting in good
time and allow the slower hoisting points to align with the rest of the truss or truss structure.
11. Once the truss has reached the desired height, attach safety slings as required. Always check the necessity
for this against the requirements of national, regional or local regulations.
WARNING: Danger of falling from a height.
Climbing in the Interal Intertruss is strictly forbidden.
12. This is not even permitted for adjusting or maintaining the spotlights mounted in the truss. The truss has
been designed to withstand static loads and NOT the kind of additional loads that are generated by the
movements of a person climbing in the truss, or the forces that are exerted on a safety line attachment
point if the person in the truss were to fall. Use a cherry-picker or telescope lift for work on the spotlights, or
lower the entire structure back down.

MANUAL
dismantling
1. Dismantling takes place in the reverse order to assembly.
2. The use of a copper-headed hammer is recommended when loosening the truss pins.
WARNING: Risk of injury by truss pins travelling at high speed.
It may sometimes be necessary to use a steel hammer to loosen jammed truss pins. Only use
a steel hammer if the exit route of the pin has been shielded effectively. The pins can sometimes
loosen abruptly and fly out at high speed.
3. Pick up the truss pins straightaway and check them for damage. Put undamaged pins back in the pin storage
box and lay the damaged ones aside for repairs.
WARNING: Risk of slipping or stumbling.
Leaving pins lying around on the ground increases the risk of somebody slipping or stumbling
in high traffic areas where truss parts are carried from place to place.
4. Load the truss modules onto a trolley or dolly and secure them with a ratchet strap. Roll the loaded dollies
away from the working area.
Maintenance:
The Interal truss requires little maintenance, but is not totally maintenance-free. The parts that require the most attention
are the steel truss pins and the conical coupling components.
1. The truss pins should be viewed as consumables. Conscientious maintenance and/or timely replacement
of these pins will extend the service life of the truss sections.
The truss pins should not exhibit mushroom-shaped burrs as a result of heavy blows with a hammer. Burrs
at the thin end in particular will significantly reduce the service life of the trusses and have a detrimental effect
on ease of assembly. Deburr the pins regularly using a grinding stone or abrasive paper and lubricate
them with silicon spray or some other form of lubrication. The pins should be thrown away when bent or
worn, or if the R clip hole is no longer useable.
2. Conical couplings that exhibit burrs or dents due to contact with other objects should also be smoothed
down using abrasive paper, blown clean and then lubricated with a silicon-based oil.
3. The inside surface of the conical sleeves (attached to the truss tubes) should be checked for burrs on a
regular basis. If burrs are found, the inside of the sleeves must be lightly rubbed down with abrasive paper
to remove the burrs, blown clean and then lubricated with a silicon-based oil.
4. Bent diagonals and end tubes can generally be straightened with a hammer. Use a wooden wedge to protect
the aluminium.
5. It is also recommended that all the coupling components are cleaned and lubricated again during the annual
service.

accordance with DIN standards 4113 Part 1 and Part 2. Whenever dynamic loads are expected, the loading figures should
be reduced by 50% (we recommend to perform a new calculation). For other loading conditions a structural engineer or
Interal T.C. should be consulted.
The load tables assume that the means of
attachment of the loads (clamps, slings, etc.)
that are hung from the truss will be located as
closely as possible to a point where several
diagonals come together.
