MAFI trailer explained: dimensions, use, advantages in the RoRo terminal

March 5, 2026
Reading time: 5 minutes

A mafi trailer roro is a specially designed rolling platform for the transport of non-roadworthy goods on RoRo ships. It is moved in the terminal by terminal tractor units and enables the safe shipment of construction machinery, project cargo and oversized units. Typical advantages are high load capacity, flexible dimensions and efficient processes in the RoRo terminal. Correct documents such as B L, clear POL POD information and precise ETD ETA planning are crucial for smooth handling.

Short answer in 5 points

A mafi trailer roro serves as a mobile loading platform for non-self-propelled goods in RoRo transport.

It is moved in the terminal by special tractor units and rolled on board.

Typical applications include construction machinery, transformers, steel structures and extra-wide loads.

Important documents are B L, freight documents and correct information on POL POD and ETD ETA.

The costs depend on dimensions, weight, route and terminal requirements and require a customised offer.

Introduction: Why MAFI trailers are so important in RoRo

RoRo stands for Roll on Roll off and describes a shipping method in which cargo is driven or pulled on board via ramps. While cars or lorries roll independently, goods that are not ready to travel require a technical solution. This is where the mafi trailer roro comes into play.

The MAFI trailer plays a central role in modern RoRo terminals and on PCTC ships. It acts as a link between the terminal, ship and recipient. Especially with heavy project cargo, it often becomes clear in practice that the choice of the right trailer is decisive for safety, efficiency and cost structure.

What is a MAFI trailer in RoRo transport?

A MAFI trailer is a robust steel platform without its own drive. It has solid axles, a low loading height and high load capacities. In contrast to standard semi-trailers, it is designed for extreme point loads and handling in harbours.

The term mafi trailer roro specifically describes the use of this platform in the roll on roll off system. The trailers are moved in the terminal with so-called tugmasters or terminal tractors. The load remains fixed to the trailer during the entire sea transport.

Typical technical features

Low overall height for heavy machines

High load capacity, up to well over 100 tonnes depending on type

Sturdy steel construction for point loads

Multiple lashing points according to CTU code

In practice, different variants are used, including 40-foot, 60-foot and special versions for extra-long goods.

Which dimensions and load capacities are common

The dimensioning depends on the intended use. The following categories are particularly common in RoRo terminals:

40 foot MAFI trailer for medium-heavy machines

60 foot platforms for long components

Heavy-duty MAFIs for transformers or industrial plants

Important parameters for planning are

Total length of the load

Total weight including trailer

Point load distribution

Excess width or excess height

In practice, it is often the case that not only the total weight, but above all the axle load distribution is decisive. An incorrect weight specification can lead to delays in the terminal.

How is the operation in the RoRo terminal organised

Delivery to the terminal

The cargo is delivered to the port by lorry or heavy transport. It is then reloaded onto the mafi trailer roro. Special ramps or cranes are used for this.

Securing the load

Lashing is carried out in accordance with international standards. Among other things, the IMO CTU Code is decisive. Proper securing prevents damage during the sea voyage.

Congestion on board

In the next step, a terminal tractor pulls the loaded trailer on board via the rear or side ramp. There it is secured in a designated position.

Unloading at the port of destination

The trailer is unloaded at the POD and the load is either taken over directly or transported onwards.

Precise coordination of ETD ETA and transparent communication between the shipper, shipping company and terminal are essential.

What documents are required for mafi trailer roro shipments

Complete documentation prevents delays and additional costs.

Bill of Lading B L

The B L is the central transport document. It contains information on:

Sender and recipient

POL POD

Description of goods

Weight and dimensions

Technical data sheets

Particularly in the case of construction machinery, information on:

Weight

Dimensions

Ground clearance

Centre of gravity

required.

Customs and export documents

Depending on the route, export declarations, certificates of origin or special authorisations are required.

In practice, it is often the case that incomplete dimensions lead to recalculations or delays.

What advantages does a MAFI trailer offer compared to other methods?

High flexibility

Goods that are not ready to travel can be transported without complex containerisation.

Efficiency in the terminal

The rolling principle reduces handling times. The mafi trailer roro remains under the load during the entire sea transport.

Security

The stable construction minimises the risk of movement during the voyage.

Cost efficiency for large loads

RoRo is often more economical than breakbulk or flat rack containers, especially for oversized machines. However, specific costs depend on the route, weight and availability and require a customised offer.

Typical areas of application

Construction machinery

Agricultural machinery

Industrial plants

Transformers

Extra-wide steel structures

What risks and errors frequently occur

Incorrect weight information

Unrealistic or estimated weights lead to congestion problems.

Inadequate load securing

Missing lashing points or incorrect securing can cause damage.

Missing documents

Incomplete B L details or incorrect POL POD data will delay despatch.

EU ETS effects

Since the introduction of emissions trading for maritime transport, the EU ETS also affects RoRo transport within Europe. Information on this is provided by the EU Commission:

In practice, companies should examine possible additional regulatory requirements at an early stage.

Checklist for shipping with mafi trailer roro

Measure dimensions precisely

Check total weight and axle load

Provide technical data sheets

Specify POL POD correctly

ETD ETA realistic planning

Coordinate lashing concept

Prepare customs documents

Early coordination with the shipping company or freight forwarder significantly reduces risks.

FAQ on the MAFI trailer in the RoRo

What does it cost to use a MAFI trailer in a RoRo

The costs depend on the route, weight, dimensions and terminal charges. It is not possible to provide a generalised quote. A customised offer is required.

Any machine can be transported on a MAFI trailer

In principle, yes, as long as the weight and dimensions are within the technical specifications and secure lashing is possible.

What does mafi trailer roro mean in contrast to container transport

During container transport, the load is stowed in a closed container. With the mafi trailer roro, the goods remain open on a platform and are loaded on wheels.

How long does handling take in the terminal

The duration depends on the port, capacity utilisation and document situation. If the documents are complete, handling is usually very efficient.

What role do ETD and ETA play

ETD denotes the planned departure, ETA the expected arrival. Precise times are crucial for project planning and onward transport.

Conclusion

The mafi trailer roro is a central element of modern RoRo logistics. It enables the safe and efficient transport of heavy, non-roadworthy goods worldwide. Standardised processes in the terminal, clear documentation and professional load securing minimise risks.

Companies benefit from flexibility, predictability and efficient integration into global supply chains. Precise dimensions, complete documents and early coordination between all parties involved are crucial.
