ST315 is a standard model in the HUAYUAN mobile stage trailer series. It uses a trailer-based integrated stage structure and hydraulic deployment system, balancing stage area, load capacity, and operational flexibility. It is suitable for medium-scale outdoor performances and event projects.
Compared with entry-level models, ST315 provides a more complete stage space and higher structural load capacity. It can support multiple performers and a more complete lighting configuration, while keeping a reasonable transport size for frequent use in city and regional events.
This model is suitable for city cultural activities, community and regional performances, festival events, and medium-scale touring shows. It provides a reliable option for events that require stable stage conditions, but do not need a large and complex stage structure.
ST315 is optimized around overall dimensions and use requirements, achieving an efficient balance between transport and on-site deployment.
ST315 uses a standard trailer-based integrated structure. It maintains a balance between stage area and overall vehicle size, making it suitable for the transport and deployment needs of medium-scale events, and convenient for frequent use in city and regional projects.
The stage is deployed and retracted by the hydraulic system. The deployment sequence is clear, and the movements are well synchronized, reducing manual setup work and making setup efficiency for multi-session events more stable and controllable.
After deployment, a complete roof-covered space is formed, meeting the lighting equipment layout needs of medium-scale events.
The roof structure works together with the stage platform, maintaining stable support and load-bearing performance during frequent use.
Compared with entry-level models, ST315 provides a more complete stage working space, making performer movement and equipment layout easier.
It is suitable for event scenarios where multiple performers need to use the stage at the same time.
