Sany Zhuhai Port Machinery Park: 10x10m Super-Large-Span Stacking Fast Doors Installation
Project Overview
This case study documents the survey, measurement and installation of two 10 × 10 m super-large-span stacking fast doors at the Sany Zhuhai Port Machinery Park — Sporadic Production Construction Project. The project combined heavy port-machinery infrastructure with industrial fabrication, demanding a door solution engineered for extreme dimensions, high loads and a tough industrial environment.
Project Snapshot
| Project | Sany Zhuhai Port Machinery Park — Sporadic Production Construction Project |
|---|---|
| Product | 10 × 10 m super-large-span stacking fast door |
| Quantity | 2 units |
| Opening Size | 10,000 mm (W) × 10,000 mm (H) per unit |
| Site Type | Port machinery plant / large steel-structure industrial workshop |
Site Characteristics
Before fabrication began, the site presented a set of distinctive, high-demand conditions:
- Port machinery cranes — heavy-duty gantry and overhead cranes operating within the same building envelope.
- Large steel structures — a big-span steel framing system that dictated the door opening tolerances.
- Industrial workshop environment — continuous production with dust, heavy traffic and vibration.
- Heavy ground traces — compacted tracks and wear marks confirming constant passage of heavy loads.
Our Professional Survey Actions
Accurate measurement is the foundation of any 10,000 mm wide by 10,000 mm high opening. To guarantee a perfect fit, our engineering team carried out:
- Multi-point measurement — recording width, height and depth at multiple points across each opening to capture structural deviation.
- Diagonal cross-check — verifying both diagonals to confirm squareness and prevent door binding or misalignment.
- Ground, wall and top survey — inspecting the floor condition, wall flatness and uprightness, and the structural top rail to define fixing points and load paths.
Each step ensured the 10 × 10 m super-large-span stacking fast doors could be manufactured and pre-assembled offline, then delivered for a fast, low-risk installation.
Why a Super-Large-Span Stacking Fast Door
| Challenge | Solution |
|---|---|
| 10 × 10 m clear opening | Super-large-span stacking fast door design with reinforced guide rails |
| High wind & industrial loads | Structural frame engineered for port environments |
| Heavy crane & vehicle traffic | Fast opening/closing to limit heat loss and dust ingress |
| Frequent heavy passage | Robust hardware and safe stacking mechanism |
Results & Value Delivered
With meticulous on-site verification and a purpose-built pairing of doors, the project delivered:
- Two perfectly fitting 10 × 10 m super-large-span stacking fast doors;
- Reduced installation time thanks to pre-verified dimensions and diagonal checks;
- Improved workshop sealing, energy efficiency and dust control for the port machinery plant;
- A repeatable, verifiable measurement method suitable for large industrial openings.
Conclusion
Sany Zhuhai Port Machinery Park required a door solution strong enough for heavy port infrastructure and large enough for a 10 × 10 m opening. Through multi-point measurement, diagonal cross-checking and a comprehensive ground/wall/top survey, our team ensured both super-large-span stacking fast doors were installed accurately, safely and reliably.
