What Is This Structure?

This is not part of the finished lighting truss structure.

It is a temporary mobile access and working-platform system used during truss installation.

The relationship is:

Outdoor Lighting Truss
= structure being assembled and installed

Mobile Aluminum Scaffold Tower
= temporary structure allowing installers to reach the elevated assembly positions

That distinction is important on DragonStructure.

The scaffold does not become a supporting tower for the finished lighting truss simply because it is positioned beneath or beside the truss during installation.

Two Scaffold Configurations in One Installation System

Configuration A — 0.75m Single-Width Mobile Scaffold

The single-width version uses:

0.75m-wide ladder/frame modules

with a 5.22m overall product configuration.

Its narrower tower body makes it useful where the installer needs elevated access without occupying the same width as a double-width working tower.

Confirmed packing information:

Configuration B — 1.35m Double-Width Mobile Scaffold

The double-width version uses:

1.35m-wide ladder/frame modules

with the same 5.22m product-height configuration.

Its wider tower body allows a larger working-platform arrangement.

Confirmed packing information:

So although both structures address approximately the same vertical working range, they are not the same scaffold with a different label.

Their platform layout, brace quantities, packing weight and volume are different.

Structural Breakdown

1. Modular Aluminum Frame System

Both scaffold towers are built vertically from modular aluminum frames.

For this 5.22m configuration, the source BOQs use two principal frame heights:

• 2.31m 5-rung frame

• 1.848m 4-rung frame

The tower is therefore created by stacking different frame modules rather than fabricating one continuous 5m-high ladder structure.

This modularity allows the scaffold system to be configured around different working-height requirements.

2. Integrated Ladder Access

Both configurations include dedicated frame-with-ladder modules.

Instead of requiring a completely separate external access structure, the climbing route is integrated into one side of the scaffold frame system.

For the 5.22m configuration, both single and double-width BOQs include:

• one 2.31m frame with ladder;

• one 1.848m frame with ladder.

The ladder therefore forms part of the tower's vertical access arrangement.

3. Horizontal Connections

Horizontal Bar SD2 members connect the tower frames.

The quantity differs between the two configurations:

• Single width: 8 pcs

• Double width: 6 pcs

This is a useful example of why BOQs should not be converted simply by changing the tower width.

A 0.75m tower and a 1.35m tower may reach the same nominal height, but their component combinations are not necessarily identical.

4. Diagonal Bracing

Both configurations use SD1 diagonal bars.

The supplied BOQs specify:

• Single width: 4 pcs

• Double width: 8 pcs

The diagonal members brace the modular tower bays and are visibly part of the scaffold configuration.

This describes the physical arrangement only. It should not be interpreted as a calculated statement about allowable loads or structural capacity.

5. Working Platform Arrangement

This is one of the clearest differences between the two towers.

Single Width

The BOQ specifies:

Trap Door Platform SD7 — 2 pcs

The narrow tower therefore uses two trapdoor platform units in this configuration.

Double Width

The BOQ specifies:

• Trap Door Platform SD7 — 1 pc

• Platform SD6 — 2 pcs

The 1.35m width provides space for a broader platform arrangement combining an access platform with additional standard platforms.

This helps explain the practical difference between the two systems:

Single width prioritizes a narrow tower body; double width provides a broader working deck configuration.

6. Upper Working Zone

At the upper part of each tower, the platform, guardrail and toe-board components create the principal elevated working zone.

The BOQs include:

• Toe Board SD7

• Guardrail SD9

• working/access platform components

The site photograph shows these upper work zones extending above the lighting truss installation elevation, allowing installers to work from an elevated position rather than standing on the truss itself.

However:

5.22m scaffold height ≠ 5.22m platform height ≠ 5.22m worker reach.

These dimensions must be distinguished when configuring a scaffold for another project.

7. Mobile Wheel and Adjustable Leg Assemblies

Both scaffold versions use:

6-inch wheel and adjustable leg — 4 pcs

The casters allow the tower to be repositioned between work locations.

This matters particularly during truss installation.

A lighting truss system may contain multiple:

• corners;

• horizontal beams;

• vertical towers;

• connection points;

• upper assembly positions.

A mobile access tower can therefore be used at one installation point, brought down to a relocation condition, repositioned, and then prepared for work at the next position.

The presence of casters should not be interpreted as permission to move the scaffold while occupied.

8. Long Outriggers

Both configurations include:

3m Long Outriggers — 4

The outriggers project beyond the central tower footprint and form an important part of the working-position configuration.

This creates an important planning distinction:

Tower width is not the same as total operating footprint.

For the single tower, 0.75m describes the main frame width.

For the double tower, 1.35m describes the main frame width.

Once the long outriggers are deployed, both structures occupy substantially more ground area.

This must be considered when positioning scaffold towers around an outdoor truss structure.

Why Use Both Single and Double Scaffold Towers on the Same Truss Project?

The site image provides the most useful answer.

It shows that temporary installation access does not necessarily require every scaffold tower to have the same width.

Different positions around the truss can create different working requirements.

Single Width — When Access Space Matters More

A 0.75m tower reduces the central scaffold width.

It can therefore be useful when the tower needs to fit closer to:

• truss legs;

• other scaffold towers;

• stage structures;

• buildings;

• equipment;

• restricted installation corridors.

The trade-off is a narrower working-platform arrangement.

Double Width — When Working Platform Area Matters More

The 1.35m double-width configuration creates more room inside the tower.

The BOQ itself reflects this through the use of:

1 trapdoor platform + 2 standard platforms.

This makes the double-width tower more suitable where a broader elevated working area is useful and sufficient ground space is available.

The Real Selection Logic

The practical choice is therefore not:

Single width = small project
Double width = large project

A better way to think about it is:

Available Ground Space + Required Working Area + Installation Position → Scaffold Width Selection

This is why a single truss installation project can reasonably use both configurations.

How the Scaffold Works with the Lighting Truss

The site photograph shows a rectangular aluminum truss structure under installation, with scaffold towers positioned inside or adjacent to the truss footprint.

The functional relationship can be understood as:

Ground
↓
Mobile Scaffold Base / Outriggers
↓
Modular Aluminum Scaffold Tower
↓
Elevated Working Platform
↓
Installer Working Position
↓
Lighting Truss Connection / Installation Area

The scaffold provides human access to the truss.

It should not be described as carrying the completed lighting truss unless a specific engineered support arrangement has been separately established.

Why This Is Different from a Lighting Truss Tower

This distinction is particularly important for SEO and customer understanding.

Lighting Truss Tower

Its function is part of the event structure itself.

It may form part of:

• lighting support;

• roof structure;

• horizontal truss support;

• production equipment support.

Mobile Scaffold Tower

Its function is temporary:

• installer access;

• assembly access;

• elevated working platform;

• maintenance access.

Once the truss installation is complete, the scaffold can be removed.

So on DragonStructure, this product belongs primarily under Mobile Access Structure, not Lighting Truss Structure.

The registered Dragon Internal Link Library defines Mobile Access Structure specifically for mobile access towers, movable work structures and temporary elevated maintenance access.

BOQ — 5.22m Single-Width Mobile Scaffold

Packing Information

Weight: 132kg
Volume: 1 CBM

The zero-quantity 3-rung frames are retained here because they appear explicitly in the supplied source BOQ; they are not used in this 5.22m configuration.

BOQ — 5.22m Double-Width Mobile Scaffold

Packing Information

Weight: 170kg
Volume: 1.65 CBM

Single vs Double Width — BOQ Comparison

This comparison is one of the strongest sections of the page because it demonstrates that the two scaffold configurations share the same basic installation function but use different structural/component arrangements.

Assembly Logic

At a structure-breakdown level, both towers follow the same general sequence:

Wheels / Adjustable Legs
↓
Lower Frame Pair
↓
Horizontal + Diagonal Bracing
↓
Platform / Access Level
↓
Upper Frame Pair
↓
Upper Working Platform
↓
Guardrail + Toe Board Zone
↓
Long Outriggers for Working Configuration

The exact brace and platform arrangement differs between the single and double-width versions according to the supplied BOQs.

This is a structural explanation, not a substitute for the manufacturer's assembly procedure.

Suitable Applications

Although this page is based on an outdoor lighting-truss installation example, the same access logic can apply to:

• outdoor lighting truss installation;

• concert truss assembly;

• temporary event structure installation;

• stage truss maintenance;

• LED structure installation access;

• exhibition structure assembly;

• indoor or outdoor AV installation;

• building-services installation;

• temporary elevated maintenance.

The key requirement is temporary elevated human access, rather than permanent equipment support.

Configuration Variables

Before selecting a similar scaffold tower, confirm:

Required Installation Height

Where is the actual truss connection or equipment installation point?

Required Platform Height

Do not select the tower only from the overall structure height.

Available Ground Space

Can a 1.35m double-width tower fit, or is a 0.75m single-width tower more practical?

Required Working Area

Does the installer need only an access position, or a broader platform for installation work?

Truss Geometry

Where are the columns, horizontal beams and connection points?

Number of Installation Positions

Will one mobile tower be repositioned, or are several towers required simultaneously?

Outrigger Space

Can the 3m outriggers be deployed around the installation area?

Ground Condition

Is the working area level and suitable for the proposed mobile scaffold configuration?

Indoor / Outdoor Environment

Outdoor installation introduces site conditions that cannot be determined from tower dimensions alone.

What the Site Photo Teaches Us

The photograph makes this product substantially more useful as DragonStructure content than the two original standalone sales pages.

Looking only at the catalog products, the question is:

“Should I buy a 0.75m scaffold or a 1.35m scaffold?”

Looking at the actual installation site, the better question becomes:

“Which working positions need narrow access, and which positions benefit from a wider working platform?”

That is a structural-planning question.

It also explains why standardization does not necessarily mean using one scaffold size everywhere.

A project can standardize around the same mobile scaffold family while still using different tower widths according to different working positions.

This is experience-based project interpretation from the supplied site image, not a verified engineering conclusion.

Experience-Based Interpretation

Using both tower widths can provide different access solutions around different truss installation positions: narrower access where floor space is constrained and a wider working area where sufficient space is available.

Not Established by the Supplied Material

The supplied information does not establish:

• allowable platform load;

• allowable number of workers;

• truss load capacity;

• whether the scaffold can temporarily carry any truss load;

• maximum permitted platform elevation for every assembly;

• required outrigger geometry for every site;

• wind rating;

• allowable outdoor wind condition;

• ground-bearing requirements;

• ballast requirements;

• safety factor;

• certification;

• code compliance;

• engineering approval.

In particular, the outdoor photograph should not be used as evidence that this exact configuration is suitable for every outdoor condition.

Information Needed for a Similar Truss Installation

For a similar project, please provide:

• truss drawing;

• truss overall width, depth and height;

• installation/connection elevations;

• site photographs;

• available ground space;

• required working-platform height;

• number of installers;

• number of simultaneous working positions;

• preferred single or double-width tower;

• whether towers need to be repositioned during installation;

• ground condition;

• indoor or outdoor application.

With this information, the scaffold configuration can be selected around the actual installation workflow, rather than choosing tower height alone.

FAQ

Why would one lighting truss project use both single and double-width scaffolds?

Different installation positions can have different access and working-area requirements. A 0.75m single-width tower reduces the central footprint, while a 1.35m double-width tower provides a wider platform arrangement.

Is the single-width scaffold simply a lighter version of the double-width scaffold?

No. The supplied BOQs show different brace and platform combinations. The single tower weighs 132kg and packs into 1 CBM, while the double tower weighs 170kg and packs into 1.65 CBM.

Does a 0.75m scaffold require only 0.75m of ground space?

No. The 0.75m dimension describes the tower frame width. The 3m outriggers extend the operating footprint beyond the central tower.

Does the scaffold support the lighting truss during installation?

This page treats the scaffold as a temporary installer access and working structure. The supplied evidence does not establish it as a structural support for the lighting truss.

Should I choose the scaffold according to truss height?

Truss height is only one variable. Required platform elevation, installation point, available ground space, working area and outrigger space should also be considered.

Can the same scaffold be moved between several truss installation points?

The towers use casters and are mobile structures, so repositioning is part of their practical function. However, movement and working-position procedures must follow the applicable scaffold operating requirements; mobility should not be interpreted as permission to move the tower while occupied.

Final Structure Classification

Short Description

A 5.22m modular aluminum mobile scaffold access system used for elevated work during outdoor lighting-truss installation. The project combines 0.75m single-width and 1.35m double-width towers within the same installation environment: the narrow configuration reduces the central tower footprint, while the double-width configuration provides a broader working-platform arrangement. Both use modular ladder frames, horizontal and diagonal bracing, mobile wheel assemblies, elevated platforms, guardrails, toe boards and 3m outriggers. The scaffold functions as temporary installer access rather than as part of the finished lighting-truss support structure.
