How to Install a Double Wing Expandable Container House in 2 Hours
– Step-by-Step Guide
Our Double Wing Expandable Mobile House ships compactly as a
standard 20FT container and unfolds on-site into a spacious,
ready-to-use living or working space. This practical guide walks
you through the entire installation process so you can be
operational within hours. Designed for overseas buyers, the system
requires minimal tools, no heavy construction, and no concrete
foundation in most cases.
Why This Guide Matters
With proper preparation, a small team can complete the full
deployment in 1–2 hours. The unit arrives factory-finished with
insulated sandwich panels, pre-wired electrical systems, and
pre-routed plumbing stubs — minimizing on-site work.
1. Transportation & Delivery Preparation
The Double Wing Expandable Container House is engineered for
standard international shipping. It fits perfectly on flatbed
trucks, container ships, and most logistics networks without
special permits in many regions.
- Transport dimensions: Standard 20FT container size (approx. 6.058m
× 2.438m × 2.896m)
- Weight: Typically 8–12 tons depending on customization
- Delivery tips: Ensure clear access road (minimum 4m width) and
level unloading area. Use a 20–40 ton crane or telehandler for
offloading.
- Pre-delivery checklist: Confirm ground preparation is complete
before arrival to avoid delays.
2. Required Tools & Manpower
| Item | Details |
|---|
| Manpower | 2–3 people (1 supervisor + 2 technicians) |
| Lifting Equipment | Forklift, telehandler, or small crane (minimum 12-ton capacity) |
| Basic Tools | Impact drill, socket set, level, measuring tape, rubber mallet,
utility knife |
| Additional | Adjustable leveling feet (included), gravel or concrete blocks for
base |
3. Ground Preparation (No Concrete Foundation Needed)
One of the biggest advantages is minimal site work. The unit can be
installed on various surfaces:
- Compacted gravel pad (recommended 150–200mm thick)
- Concrete blocks or precast piers at corner and mid points
- Adjustable steel leveling feet (included) handle up to 150mm ground
variation
- Ensure the area is level within 50mm and free of sharp objects or
vegetation
Note: In high-wind or seismic zones, consult a local engineer for
additional anchoring recommendations.
4. Step-by-Step Installation Guide
Step 1: Positioning the Unit
Place the folded container precisely on the prepared base using
lifting equipment. Align with your site layout. Use a spirit level
to check all four corners. Adjust the leveling feet until the unit
is perfectly horizontal.
Step 2: Unlocking Transport Locks
Remove all transport safety pins and bolts from the side wings
(usually 8–12 locking points). These are clearly marked at the
factory.
Step 3: Expanding the Double Wings
Using the built-in hydraulic assist or manual winch system (model
dependent), gently unfold both side wings outward. The wings open
like large doors, creating the expanded living space. Lock the
structural joints with provided bolts for rigidity. This step
typically takes 20–40 minutes.

rectangular expanded structure with flat roof and increased width.)
Step 4: Roof & Panel Securing
Install any roof flashing or sealing strips along the expansion
joints. Check that all sandwich panels are firmly seated and
sealed.
Step 5: Final Stabilization
Tighten all corner and base connections. The unit is now
structurally sound and ready for utility connections.
5. Water & Electricity Connections
All internal wiring and plumbing are pre-installed. You only need
to connect external supplies:
- Electrical: Connect the main distribution board to your power source
(220V/50Hz standard). Pre-wired sockets, lights, and switches are
ready.
- Plumbing: Hook up fresh water inlet and drainage outlets to site
infrastructure. Bathroom and kitchen stub-outs are pre-positioned.
- Optional: Solar panel brackets on the flat roof make off-grid setup simple.
6. Post-Installation Maintenance Tips
- Inspect seals and expansion joints every 6 months
- Clean sandwich panel surfaces with mild detergent to maintain
appearance
- Check leveling feet after heavy storms or ground settlement
- Galvanized steel frame requires minimal rust treatment in normal
conditions
- Design service life: 20–30 years with standard care
Common Installation Questions (FAQ)
Do I need a crane for installation?
A forklift or telehandler is usually sufficient. A small crane is
recommended only for difficult terrain.
Can one person install it alone?
We recommend 2–3 people for safety and efficiency. Experienced
users can manage with 2.
What if the ground is not perfectly level?
The adjustable leveling feet compensate for up to 150mm difference.
Minor additional shimming may be used if needed.
How long until I can move in or start working?
Utility connections can be completed within 1–2 hours after
expansion, allowing immediate use.
Is it possible to relocate the unit later?
Yes. The process is reversible — fold the wings, secure transport
locks, and move to a new site.
