Advantages of the tugger train at a glance

Tugger trains consist of a towing truck and trailers that carry the load. But not all tugger trains are the same; there are different designs and concepts that can be used for different applications.


A comparison of tugger train concepts

Not all tugger trains are the same. One key difference is the type of trailer used.

Each trailer carries the load in a different way:

  • Trailer conzept: the load is placed directly onto the trailer
  • Taxi concept:: the carrier is pushed onto the trailer via a ramp attached to the side and taxied
  • Push concept: the carrier is pushed onto the trailer

The concepts not only have technical differences but also vary in the effort and cost required to implement and operate them. The important question to consider is why the tugger train is being implemented now and how it must be designed to fit the company perspective.

The trailer concept is often used as a first step but can become problematic later if the company perspective favours the use of a push system. Trailer systems have long process and load handling times. They are relatively inflexible, cannot be combined with digital information systems and even in low quantities are very cost-intensive.

Push systems, in contrast, are flexible and can be used as a foundation for digitalising and automating the material flow.

The comparison at a glance

Trailer concept
The load is placed directly on the trailer.

The structure of the trailer concept is simple. The load or carriers (e.g. pallets) are placed directly on the trailers. The trailer concept is quite easy to install and has low procurement costs – even in very low quantities – and so is a popular choice for those choosing their first system. When selecting a system, we recommend you consider your long-term application and process development requirements.


  • Easy to implement
  • Small load carriers can be moved individually and not the large load carriers


  • Individual trailers are generally disconnected from the towing vehicle and placed directly on the line; alternatively, an additional vehicle is required at the sink points to unload the tugger train
  • Inflexible handling
  • Static rollers and high process times
  • Complex unloading process on the production line
  • No options for further development, no combination with digital systems or automation possible
  • In the long term, the trailer concept incurs higher costs than the push concept
  • Poor ergonomics due to rollers with high roll resistance
  • Low maximum speed and poor drive properties

Taxi concept
The carrier is pushed onto the trailer via a ramp attached to the side and taxied.

The trolleys can be loaded from both sides. In terms of process development, the taxi concept comes in second place between the trailer and push systems. Depending on the supplier, digital processes can be implemented.


  • Can be loaded on both sides
  • Trolleys are on the line and not on the floor


  • High power required for loading
  • Heavy devices with poor visibility
