50 Reviews
The DragonStage 9x6m Bolt Truss Gantry System is a modular event-support structure featuring two vertical truss towers, a horizontal bolt-connected truss beam, tower-head assemblies, base plates, and diagonal outrigger bracing.
With a nominal horizontal dimension of 9m (29.5ft) and a height of 6m (19.7ft), this open-frame structure is intended for event lighting, stage production, backdrop framing, and temporary gantry applications. Final truss specifications, support arrangements, and equipment loads are confirmed according to the project requirements.
The DragonStage 9x6m Bolt Truss Gantry System is a modular, ground-supported truss structure designed for event-production applications requiring an elevated horizontal truss beam.
The system consists of two vertical support towers connected by a horizontal truss beam. Each tower is illustrated with a base assembly, diagonal bracing, and a tower-head assembly.
The nominal dimensions shown in the drawing are:
Horizontal Dimension: 9m / 29.5ft
Overall Height: 6m / 19.7ft
The 9m dimension is taken from the supplied drawing between the indicated support positions. The final outside width, beam length, and clear opening should be confirmed from the production drawing.
This structure is particularly relevant to event companies looking for an open gantry configuration rather than a complete roof or enclosed stage structure.
The defining feature of this product is its two-tower support arrangement.
The illustrated structure includes:
One vertical truss tower on each side
One horizontal bolt-connected truss beam
Tower-head assemblies
Base plates
Diagonal outriggers and bracing members
Modular connection sections
The horizontal beam provides the main elevated truss line, while the two towers form the supporting structure on either side.
Unlike a simple truss arch assembled directly with vertical legs, this configuration includes additional support members around the tower bases.
The actual capacity and stability of the assembled structure depend on the final component specifications and verified support conditions.
Bolt-Connected Truss Structure
The system uses bolt-connected truss components rather than a spigot connection arrangement.
Bolt truss sections are connected using matching end plates, bolts, nuts, and other specified fasteners.
For rental and event companies, separate modular sections are useful for transportation, storage, maintenance, and replacement.
However, bolt-connected truss systems are not automatically interchangeable simply because they have similar external dimensions. Their end-plate geometry, bolt-hole spacing, fastener specifications, and structural design must also match.
The gantry includes one horizontal box truss beam connecting the two support towers.
The nominal horizontal dimension shown in the drawing is 9m.
This elevated beam can form the basis for an event-lighting or overhead production layout, subject to confirmation of allowable loads, equipment positions, and supporting structure.
The final beam section sizes, component lengths, connection arrangement, and equipment positions should be established in the assembly drawing.
6m High Vertical Support Towers
Both sides of the gantry use vertical truss towers.
The drawing indicates a nominal overall height of 6m.
Each tower includes a base assembly and diagonal support members near the lower section.
The upper part of each tower also includes an additional tower-head assembly.
Although these top components are visible in the drawing, their precise function and whether they form part of a lifting mechanism have not been specified.
Therefore, the product should not be advertised as a motorized lifting system or manually operated lifting gantry without confirmation of the actual equipment.
Base Plates and Diagonal Outrigger Bracing
The lower support arrangement is an important feature of this configuration.
Each illustrated tower is equipped with a base plate and diagonal bracing extending outward from the main tower.
This differs from a simple vertical truss leg placed directly onto a flat base.
For this type of temporary structure, the complete support arrangement should be selected according to the actual installation conditions.
The provided drawing does not establish the required ballast, anchoring method, foundation design, or allowable external loads.
These requirements must be confirmed for the complete assembly.
Designed for Event Lighting and Open Gantry Applications
The system can be considered for event-production layouts requiring a freestanding overhead truss line.
Potential applications include:
Event lighting frameworks
Concert production structures
Indoor stage truss systems
Temporary gantry installations
Exhibition production areas
Stage backdrop framing
Corporate event structures
Festival production applications
For lighting fixtures, hanging equipment, banners, or other added loads, the complete structure must be checked according to the final installation.
Why Choose a Twin-Tower Gantry?
A twin-tower gantry provides a defined overhead beam between two separate support positions.
This arrangement can be practical when an event requires a truss beam across an open working area but does not need a full roof framework.
It also allows the horizontal truss, tower components, base assemblies, and connections to be supplied as separate modular elements.
For rental companies, these components may be useful in future compatible layouts, provided the new configuration is properly specified and verified.

FAQ
What is the size of this bolt truss gantry?
The drawing specifies a nominal 9m horizontal dimension and an overall height of 6m, approximately 29.5ft × 19.7ft.
Is the 9m dimension the clear span between the towers?
Not necessarily. The 9m dimension is shown between support positions in the illustration. The final clear opening and overall outside width should be confirmed from the production drawing.
What type of truss connection does this system use?
The product is specified as a bolt-connected truss system.
How many support towers does the gantry have?
The illustrated system uses two vertical truss towers, one on each side of the horizontal beam.
Does the system include diagonal braces?
Yes. The drawing shows diagonal outrigger bracing connected to the tower support arrangements.
Can the gantry be used for event lighting?
It can be considered for event-lighting applications. The lighting fixtures, attachment positions, support interfaces, and complete loading arrangement must be verified.
Does the system include an electric hoist or lifting mechanism?
The drawing shows tower-head assemblies, but it does not confirm the lifting method or the inclusion of an electric hoist. This must be specified before ordering.
Does the gantry include a roof?
No. This is an open gantry truss configuration without a roof covering.
Can it be installed outdoors?
Outdoor suitability depends on the complete structure, site conditions, wind exposure, loads, and the verified support and anchoring arrangements.
Can the width or height be customized?
Yes. Different dimensions and truss configurations can be discussed according to the customer's project requirements.
Can existing bolt truss sections be used with this system?
Possibly, but compatibility must be confirmed by truss dimensions, connection-plate geometry, bolt specifications, and the complete structural arrangement.
What information is required for quotation?
Please provide the intended application, required dimensions, preferred truss section, equipment weights and mounting positions, indoor or outdoor use, and whether a complete tower and base package is required.
