Types of Trailers for Container Transport
What is a Container Transport Trailer?
A container transport trailer is a specialized non-motorized vehicle that forms a key component in intermodal logistics. Its main task is to ensure safe, efficient and fast transport of standardized containers (ISO or inland) between ports, railway terminals and final destinations (warehouses, factories, construction sites, etc.).
Why is the correct choice of trailer essential?
- Operational efficiency and safety: The correct type of trailer minimizes the risk of cargo damage, reduces operating costs and ensures smooth transport throughout.
- Legislative compliance: Each country regulates the maximum dimensions and weights of road combinations; choosing an unsuitable trailer can lead to fines or the need for special permits.
- Technical loading/unloading capabilities: It determines whether the cargo can be handled automatically, manually or with the help of special equipment.
- Logistics optimization: Significantly affects turnover speed, goods flow and deployment capacity.
Key parameters for trailer selection
Before selecting a trailer type, analyze the following factors:
| Parameter | Significance for trailer selection | Note |
|---|---|---|
| Container length and weight | Determines the type of chassis (20′, 40′, 45′, triple combination), number of axles, load distribution | ISO containers: 20′, 40′, 45′; inland containers have different dimensions |
| Type of cargo | Standard, refrigerated, hazardous, oversized, sensitive to handling | Reefer requires power supply, ADR requires special marking and equipment |
| Loading/unloading options | Whether a crane, reachstacker is available on site, or independent handling is necessary (tipper, sidelifter) | Important for construction sites, farms, smaller companies |
| Route and weather | Long-distance transport favors low weight and aerodynamics, city transport favors maneuverability | Robustness necessary on poor roads, cargo protection against weather |
| Legislation | Weight limits, dimensional limits (height, width), required permits for oversized cargo | In EU max. height 4 m, combination weight typically 40–44 t (depending on country and number of axles) |
Types of container trailers and their detailed characteristics
1. Container Chassis (Skeletal Trailer)
Description and principle:
A container chassis is a steel frame with axles and twist-locks, designed exclusively for container transport.
- Standard chassis: Fixed length (20′, 40′, 45′), sometimes with the option to load two 20′ containers.
- Extendable chassis: Hydraulically/mechanically extendable frame for multiple container types (greater utilization, higher purchase price).
- Variants by axles: Two-axle (lighter load, local), three- and four-axle (heavier or longer containers, higher capacity).
Technical parameters (example 40ft chassis):
- Length: 12.2 m
- Width: 2.5 m
- Deck height: 1.2–1.4 m
- Tare weight: 3.5–5 t (depending on equipment)
- Payload: up to 36 t
- Twist-locks: 4–8 pcs (depending on variant)
Advantages:
- Highest safety (fixed connection with twist-locks)
- Lowest tare weight (higher useful load)
- Fast handling in terminals
Disadvantages:
- Cannot be used for cargo other than containers
- Requires external handling equipment (crane, reachstacker)
- Limited versatility
Typical use:
Transport of standard ISO containers between ports, terminals, warehouses within long-distance and domestic transport.
2. Tilt/Tipping Trailer
Description:
A special container chassis with a hydraulic cylinder allowing the container to be tilted and slid to the ground or back onto the frame.
Design features:
- Hydraulic mechanism for tilting
- Reinforced frame, often with additional beams
- Tilting control from the cabin or via remote control
- Possibility of adding a winch for smooth lowering
Advantages:

Disadvantages:
- Higher weight and price than standard chassis
- More complex maintenance (hydraulics)
- Requires level and solid surface
Typical use:
Delivery of containers for storage (e.g. to a construction site), transport of bulk materials (container with insert), farms, small businesses.
3. Sidelifter/Side Loader Trailer
Description:
The most modern and most autonomous variant, equipped with two hydraulic cranes (front and rear), which allow loading/unloading a container without external equipment directly from the ground, from another vehicle or wagon.
Main features:
- Crane capacity up to 35–40 t
- Remote control for precise maneuvering
- Stabilizing supports (legs) for safety during lifting
- Possibility of “double stacking” (placing container on container)
Advantages:
- Complete independence from terminal equipment
- Extreme flexibility and speed of operations
- Possibility of handling even in tight spaces
Disadvantages:
- Higher purchase price (up to 3–5× more expensive than chassis)
- Higher tare weight (lower useful load)
- Requires trained operators
Typical use:
Humanitarian and military logistics, delivery to construction sites, to hard-to-reach locations, transshipment between different types of transport.
4. Flatbed Trailer
Description:
A universal trailer with a flat loading surface, without side walls, roof and often without twist-locks.
Design variants:
- Standard platform (48, 53 ft)
- Platform with folding ramp (for equipment)
- With possibility of side or top loading
Advantages:
- High versatility (containers, machinery, construction materials)

- Cargo is exposed to weather
Typical use:
One-time or occasional container transports, transport of non-standard or damaged containers, combination with other cargo.
5. Lowboy/RGN Trailer
Description:
A special trailer with a very low loading surface between the axles (40–60 cm above ground), often with a removable “gooseneck”.
Technical details:
- High payload capacity (up to 60 t)
- Multiple axles (3–5) as needed
- RGN (Removable Gooseneck) allows equipment to drive on under its own power
Advantages:
- Safe transport of high containers (High Cube, open-top)
- High stability (low center of gravity)
- Possibility of combination with oversized/overweight cargo
Disadvantages:
- Higher price and complexity of operation

How to correctly select a trailer – practical guide
1. Determine the container type and dimensions
- ISO 20′, 40′, 45′ or inland container? High Cube?
- Consider weight – for heavy cargo choose more axles.
2. Consider the loading/unloading location
- Is handling equipment available (crane, reachstacker)?
→ If not, choose a tilt or sidelifter trailer.
3. Check legislative limits
- Max. height of combination in Czech Republic/EU: 4 m (with High Cube, gooseneck chassis/lowboy must be used)
- Max. length with trailer: 16.5 m
- Max. permitted weight: 40–44 t (depending on number of axles and route)
4. Consider operating costs and frequency of transport
- Regular transport between terminals? → invest in specialized chassis.
- One-time or combined? → consider flatbed trailer.
5. Consult with experts
- Use the experience of forwarding companies and trailer manufacturers – they will recommend an optimal solution tailored to your needs.
Most common mistakes when choosing a trailer
- Underestimating weight and load distribution (axle overloading, fines)
- Ignoring height limits with High Cube containers
- Choosing a flatbed trailer for heavy or valuable containers without twist-locks (risk of shifting)
- Incorrect selection for locations without handling equipment (delays, additional costs)
