S425 is the entry-level model in the HUAYUAN semi-trailer mobile stage series. It is suitable for projects with clear requirements for stage size, transport conditions, and deployment efficiency.
With controlled dimensions and structural configuration, S425 can complete fast deployment and retraction under different site conditions, meeting the needs of multi-stop and cross-regional use.
Based on the semi-trailer structure, this model integrates a hydraulic stage deployment system. It is suitable for small and mid-size performances, brand promotions, public events, and similar application scenarios.
S425 is a small-to-mid-size semi-trailer mobile stage. It uses an integrated deployment structure design, combining the stage platform, roof, and basic suspension system within the semi-trailer structure.
It is suitable for outdoor event scenarios that require fast deployment and a moderate stage scale.
S795 is equipped with technical rooms on both sides, and an approximately 17 × 3 m rear area is added for equipment transport and personnel access.
This makes it suitable for larger-scale equipment layout and on-site circulation organization.
In the closed state, the complete vehicle keeps the form of a semi-trailer, with a transport length of 17 m.
The equipment technical rooms on both sides are integrated with the main vehicle body. In the closed state, their external positions and relationship with the vehicle body sections can be clearly seen.
Hydraulic remote control completes the deployment and locking of the main stage and the structures on both sides.
After deployment, the main stage forms an approximately 189 m² base usable area, making it suitable for clear zoning of the main stage area, equipment area, and access area.
The roof is lifted to its working height by the hydraulic system, at the same level as the high-roof configuration.
The key point of this model is that, under larger span and larger stage area conditions, the roof lifting process still maintains synchronized movement and stable posture.
Onboard accessories include stairs, guardrails, stage skirting, backdrop curtains, and power distribution-related components.
The additional technical rooms on both sides and the rear access area of S795 make it easier to assign fixed functions for equipment placement, personnel movement, and backstage management.

When the stage size is already written into the early-stage plan, S795 is more suitable as a structural premise from the beginning, rather than a later-stage enlargement adjustment.
For projects that need to arrange performance areas, equipment areas, and technical working areas at the same time, the stage scale of S795 supports overall organization better than segmented arrangement.
When the site window, approval process, or execution rhythm does not allow repeated stage status adjustments, S795 is more suitable for one-time deployment.
In some large-scale projects, the stage does not only carry the performance. It also affects circulation routes, equipment layout, and on-site management. S795 fits this usage logic better.
When a medium-to-large stage begins to feel limited in area or organization, continued adjustment only increases complexity. S795 offers a more direct solution.
For projects that require repeated execution, long-term use, or integrated delivery, S795 is closer to the usage logic of a fixed structure rather than a temporary solution.
Suitable for projects that need to organize multiple performance zones and technical work areas on one stage at the same time.
When the event flow, on-site management, and stage layout are closely connected, S795 supports more integrated deployment.
When the same stage structure needs to be used repeatedly, S795 is closer to the use logic of a fixed stage.
Suitable for projects where the stage body directly affects site planning, equipment layout, and execution rhythm.
