ST345S Mobile Stage Trailer

Triple-axle upgraded structure for medium-to-large performance events

As an upgraded model of ST315, ST345S uses a triple-axle structure. The overall stability is stronger, making it more suitable for projects with higher use intensity.

After deployment, the stage size is 8.6 × 6.45 m. Reference configuration: 2–3 people, about 40 minutes to enter equipment setup.

Compared with mid-size models, ST345S provides a larger stage area and higher roof load capacity, making it more suitable for on-site arrangements with more people and a more complete event flow.

This model uses wireless remote control or button switch control, with higher deployment and retraction efficiency.

Between stage area, use intensity, and deployment efficiency, ST345S is more suitable as an upgraded mobile stage trailer solution for medium-to-large events.

  • Triple-axle Chassis

    Triple-axle Chassis

    ST345S uses a triple-axle chassis structure.
    This structure helps distribute the complete vehicle load and provides a foundation for continuous relocation and higher-frequency use in medium-to-large events.

  • Hydraulic Opening and Closing Control

    Hydraulic Opening and Closing Control

    The hydraulic system handles the main mechanical movements for main stage deployment and retraction.
    The operation supports wireless remote control or button switch control, reducing dependence on manual handling and repeated adjustment.

  • Single-folding Main Stage

    Single-folding Main Stage

    The main stage uses a single-folding deployment format.
    After the main platform opens, it forms the primary performance area and serves as the base section for the extended stage and equipment layout.

  • Secondary Extended Stage

    Secondary Extended Stage

    After the main stage is deployed, the extended stage can be manually installed.
    This structure increases the actual usable area and supports event arrangements with more participants or longer program flow.

Products Advantages

Why Choose the HUAYUAN ST345S Mobile Stage Trailer?

  • Triple-axle Chassis for High-load Projects

    The triple-axle design supports higher load capacity and use intensity, making it suitable for continuous deployment and repeated relocation in medium-to-large projects.

  • Supports Higher-level Projects

    Compared with standard mid-size solutions, ST345S can continue to support outdoor projects after the scale increases, without immediately switching to a heavier stage solution.

  • Sufficient Reserved Space for Equipment

    After the main stage is combined with the secondary extended stage, equipment placement and personnel positions can be arranged in advance, reducing temporary on-site movement.

  • Continuous Program Transitions

    After the usable area is increased, the stage can support different program segments. The site does not need to be cleared repeatedly between stages, allowing the workflow to continue.

  • Stable Deployment Rhythm

    The main stage opening is handled by the hydraulic system. Reference configuration: 2–3 people, about 40 minutes to enter equipment setup. A fixed team can execute the process in a consistent way.

  • Investment Focused on Common Needs

    The investment in ST345S mainly focuses on stage area, use intensity, and deployment efficiency, matching the common purchasing logic of most medium-to-large projects.
