Heavy-Duty Modular Stage Platform

Heavy-duty modular stages are a professional category of stage equipment designed specifically for "high-load, high-stability" scenarios. Their core feature is that their static/dynamic load-bearing capacity far exceeds that of conventional stages Heavy-Duty Modular Stage Platform. Additionally, they enable flexible size adjustment through modular assembly, making them widely suitable for scenarios with strict requirements for load-bearing and stability—such as heavy equipment exhibitions Strong Stage Platform Design, large-scale performances Durable Stage System, and crowded events Modular Performance Stage. Their design and customization must focus on the three cores of load-bearing safety, structural stability, and durable adaptability, establishing a full-process standard from material selection to acceptance testing.

I. Three Core Structures Ensuring Load-Bearing Safety

Safety hazards of heavy-duty modular stages are concentrated in "stress concentration, tipping risks, and splicing looseness." Targeted structural optimizations are required during customization:

1. Force Balance Design: Uniformly Transfer Loads to Avoid Local Overloading

Require the manufacturer to provide a "finite element force simulation report" to ensure that the load of a single module is uniformly transmitted to 4 support legs, and the maximum stress of the frame’s crossbeams and longitudinal beams is ≤70% of the material’s yield strength Event demountable stage.

If heavy equipment Demountable stage platforms needs to be placed locally on the stage, "local structural reinforcement" must be implemented at the corresponding position—add "auxiliary support legs" Modular demountable stage and "thickened crossbeams" Demountable Stage platforms to prevent frame deformation caused by excessive local pressure.

2. Anti-Tipping Structure: Low Center of Gravity + Multi-Directional Fixing

The overall center of gravity of the stage must be controlled within 10cm of the "center of the support leg range" Modular demountable stage to avoid tipping due to center-of-gravity shift.

For outdoor scenarios or stages with a height ≥0.8m, "wind-resistant cables" must be installed Aluminum demountable stage Modular demountable stage or "ground anchor fixation" Quick assembly demountable stage to enhance wind resistance.

3. Splicing Stability Design: Reduce Joint Displacement

When multiple modules are assembled into a large stage, an "integral load-bearing longitudinal beam" must be installed at the bottom Demountable Stage.

"Anti-collision railings" must be installed at the stage edges (height ≥1.1m, horizontal bar spacing ≤30cm, made of Q345 steel and welded to the frame) to prevent stage displacement caused by accidental collisions from personnel or equipment.

II. 4 Mandatory Safety Verifications After Customization

Before delivery, heavy-duty modular stages must undergo strict testing to eliminate safety hazards and must not be put into use directly:

1. Static Load-Bearing Test

Load the stage at 1.5 times the rated load . After 24 hours, check:

No frame deformation , no panel depression, and no loose connectors;

No displacement of support legs and no significant compression of foot pads .

2. Dynamic Load-Bearing Test

Simulate personnel activities or equipment vibration: Move a 150kg weight back and forth 100 times on the stage surface, or apply vibration of 5Hz and 0.1g acceleration using a vibration table. Check:

No abnormal noise at frame joints and no loose bolts ;

No relative displacement between the panel and the frame, and no attenuation of anti-slip performance .

3. Anti-Tipping Test

Apply a horizontal thrust to one side of the stage , or simulate a Level 6 wind . Check that the stage does not tip over and the support legs do not slide.

4. Material and Process Acceptance

Verify material certificates: Q345 steel material report for the frame, zinc coating thickness test report , and panel anti-slip coefficient test report;

Randomly inspect processes: Weld flaw detection report , bolt torque records , and number of panel fixing points .
