S425 is the smaller stage-scale model in the mobile stage semi-trailer series. The base stage area is about 84 m², with extension supported. It is more suitable for projects that need the solution to be implemented quickly and are more sensitive to site access and setup organization.
Stage deployment and retraction are completed by hydraulic remote control. Under common configurations, 3–4 people can complete stage deployment in about 30 minutes, making it easier to complete key actions within a limited setup window and reserve time for system testing.
LED screens, stage lighting, line array audio systems, and power supply systems can be configured according to the project plan. It is recommended to confirm equipment positions and on-site access space during the solution stage to reduce repeated adjustment on site.
S425 retains the load-bearing base of a semi-trailer stage and hydraulic deployment method while keeping the overall scale controlled. It is suitable for outdoor projects with limited site space and transport route conditions.
In transport mode, S425 keeps the exterior form of a semi-trailer. The stage, wing panels, and roof system are retracted into the vehicle body and locked in the closed position.
The vehicle body length in transport mode is about 10 m, making route planning easier on roads with tighter turning conditions.
Hydraulic remote control drives the folding stage and the left and right wing panels to deploy.
After deployment is completed, the structure is locked, forming an approximately 84 m² usable stage area.
The roof is lifted to the working position by the hydraulic system.
The height from the stage deck to the roof is 4.7 m. This height can be used as a reference for arranging lighting, audio, and other equipment.
Standard accessories include stairs, guardrails, stage skirting, backdrop curtains, and power distribution-related components.
They correspond to stage access, safety boundaries, visual screening, and on-site power organization.

S425 uses a relatively compact semi-trailer structure. While maintaining the load-bearing capacity of a semi-trailer stage, it effectively controls the overall vehicle length and turning radius.
This structure makes it easier to enter use environments with restricted road conditions, narrower site access, or limited event area space, providing greater flexibility for project site selection.
S425 does not aim for the largest stage area or the most complex system configuration. Instead, it meets the core needs of regular performances and events through reasonable control of stage size and system configuration.
This configuration approach helps meet professional use requirements while avoiding unnecessary structural redundancy, making the overall system clearer and more controllable.
By simplifying the mechanical structure and hydraulic layout, S425 makes the deployment process more intuitive and the on-site operating steps clearer.
This design reduces dependence on operator experience. It also makes deployment, locking, and retraction easier to manage, helping reduce uncertainty during on-site execution.
Within the defined stage size range, S425 is structurally designed to carry regular stage lighting, audio systems, and performer arrangements.
Its load capacity starts from real event requirements, emphasizing safety and stability under reasonable configuration rather than blindly pursuing extreme parameters.
In the HUAYUAN semi-trailer stage series, S425 is a more compact model, mainly intended for projects with higher requirements for site adaptability and operational control.
It complements larger models in application level, providing a clear selection direction for events of different scales and conditions.
The structural and system design of S425 focuses on stability and maintainability during long-term use.
By controlling system complexity and reinforcing key structural areas, the equipment can maintain a consistent working condition across repeated use cycles, making it more suitable for projects requiring continuous use.
Suitable for community squares, small city events, and other performance scenarios where the stage scale needs to be clearly controlled.
Suitable for small and mid-size touring events that require cross-city relocation and continuous use across multiple shows.
Suitable for outdoor gatherings and related events, with a stage structure that supports basic lighting and audio system arrangement.
Suitable for campus arts performances, opening ceremonies, and other occasions that require fast setup.
