ST315S is a trailer-type stage model designed for community and small events. Its design goal is to allow stage deployment and use even when no electrical power is available.
The complete vehicle weight is controlled within 3.5 tons. It can be towed by a common pickup truck or SUV, making registration and use easier in regions such as Europe and Australia.
While meeting the basic stage area requirements for events, ST315S does not rely on external power and does not require additional equipment support. It can be deployed directly in site-restricted environments such as communities and parks.
ST315S uses a winch-driven steel cable system to complete stage deployment. The full deployment process is completed manually.
Stage deployment, support, and fixing do not rely on a hydraulic system or electric control device.
Stage deployment is completed by pulling the steel cable through the winch. The deployment sequence is defined by the structure itself.
The operation acts directly on the stage components and does not rely on an external power system.
After the stage is deployed, the trailer chassis, mechanical support legs, and stage support legs work together to complete support and fixing.
Each support point has a fixed position to keep the stage stable during use.
The truss structure connects the stage and roof into one complete structure.
After deployment, this structure forms a stable load-bearing system to support the upper stage structure.
The complete vehicle weight is controlled within 3.5 tons. Stage deployment does not rely on external power.
This design considers transport, use, and regulatory requirements, making it suitable for regions with clear limits on complete vehicle weight.

When power conditions cannot be confirmed in advance at the event site, whether the stage can be used normally becomes the first concern.
ST315S does not introduce power dependence during deployment, so the stage itself does not become an obstacle to starting the event.
When registration or cross-regional use is required, vehicle attributes often become a greater restriction than the stage itself.
The complete vehicle conditions of ST315S are more likely to be accepted within local trailer systems, reducing additional administrative and usage burdens.
Some projects do not want to coordinate generators, lighting, or audio for a single event.
As an independent stage, ST315S keeps the event workflow focused on the stage itself rather than system coordination.
When staffing is limited, whether the stage depends on specific operators directly affects sustainable use.
The operation method of ST315S is easier for fixed personnel to master over the long term, without relying on temporary technical support.
Not every stage is used for high-density performances or continuous touring.
ST315S is more commonly used for periodic, low-frequency, but long-term event arrangements as a stable basic stage.
When the event requirement clearly involves only the stage body, introducing more complex systems may instead increase management costs.
ST315S provides a more direct solution when the application boundary is clear.
Used for community festivals, neighborhood gatherings, and similar activities.
The stage usually only supports personnel performance and basic program organization.
The event site is mainly arranged temporarily, without preset power or performance system conditions.
Used for public performances, volunteer activities, or temporary public projects.
The stage serves as the event support platform only, without additional equipment or technical configuration.
Used for campus gatherings, displays, or simple performances.
The event focuses mainly on internal campus arrangements. The stage only needs to be stable and usable, rather than expanding performance effects.
Used for occasions that only require the stage to complete display, speaking, or program organization.
The stage body alone can meet the event needs, without involving system coordination.
