Special transport of oversized cargo

Special transport of oversized cargo — loads outside standard dimensions and weights — requires expert planning, the right heavy haulage fleet and abnormal load permits. ZGT has organized special transport and oversized transport from Zagreb across Croatia and the whole EU since 1996, covering route surveys, permits, escort vehicles and safe delivery of indivisible loads.

When is cargo considered oversized?

Cargo needs a special transport permit when the loaded vehicle exceeds one or more of the limits set by Croatian and EU road regulations:

  • Length over 16.50 m (tractor with semi-trailer) or 18.75 m (truck with trailer)
  • Width over 2.55 m (2.60 m for refrigerated vehicles)
  • Height over 4.00 m
  • Total weight over 40 t (44 t for intermodal transport)
  • Axle load higher than allowed for the road category

Types of oversized cargo we transport

Our fleet and team are adapted to a wide range of indivisible loads:

Industrial machinery and production lines
Energy equipment — transformers, turbines, reactors
Construction structures, bridges and silos
Ship sections and yachts
Military and special vehicles
Large steel structures

How we organize the transport

  1. 01

    Data collection.

    Dimensions, weight, center of gravity, loading points and route.

  2. 02

    Engineering route analysis.

    Clearance simulation, bridges, roundabouts, inclined road sections.

  3. 03

    Vehicle and trailer selection.

    Lowbed, telescopic or modular platform depending on the cargo.

  4. 04

    Permit procurement.

    Applications to road managers, police and transit countries for international routes.

  5. 05

    Execution and monitoring.

    GPS tracking, technical escort and 24/7 client coordination.

Trailer types we use

Trailer choice depends on dimensions, weight and shape of the cargo:

Lowbed semi-trailer.

Standard choice for machinery and industrial equipment up to 45 t. Lowers total cargo height.

Telescopic trailer.

Extends to match cargo length — ideal for long structures and ship sections.

Modular platform.

For loads above 60 t and exceptionally large dimensions; axle count adapts to the route.

Lowbed trailer with ramps.

Allows loading from a low platform without crane lifting.

Fleet technical specifications

Indicative limits per trailer type. The final combination is defined after the route survey and a review of the cargo specification.

Trailer typeUsable lengthMax cargo widthPayloadTypical use
Lowbed semi-trailer8.4–13.6 mup to 3.5 mup to 45 tMachinery, industrial equipment
Telescopic trailer13.6–21 mup to 3.0 mup to 40 tGirders, poles, ship sections
Modular platformconfigurableup to 6.0 m60 t and aboveTransformers, reactors, structures
Flatbed / mega trailer13.6 mup to 2.55 mup to 24 tVolumetric and lighter indivisible loads

Industries we serve

Typical special transport assignments by industry:

Power and energy.

Transformers, turbine and wind-farm components, boilers and pressure vessels moved to and from project sites.

Construction.

Excavators, cranes, concrete plants, precast concrete and structural steel elements.

Manufacturing and plant engineering.

Production line relocations, presses, machine tools and complete process units.

Shipbuilding and marine.

Hulls, sections, masts and yachts up to 3.5 m beam transported without dismantling.

Permits and escort

Every special transport in Croatia requires a permit from Hrvatske ceste (HC) or Hrvatske autoceste (HAC), and a police or technical escort once the load exceeds certain dimensions. For international oversized transport we coordinate permits for every transit country — Slovenia, Austria, Germany, Italy, Hungary, Serbia and beyond — align the validity windows, and plan night-time or convoy movements where local rules require them, so the cargo moves without delays at the border.

Frequently asked questions

What is oversized cargo?

Oversized cargo is cargo that, together with the vehicle, exceeds one or more legal dimensions: length 16.50 m (semi-trailer) or 18.75 m (truck with trailer), width 2.55 m, height 4.00 m or total weight 40 t. An exceptional transport permit is required.

How much does special transport of oversized cargo cost?

The price depends on cargo dimensions and weight, route length, the number of countries crossed, permit and escort requirements, and trailer type. Each quote is prepared individually after a route analysis and a review of the cargo specifications and drawings.

How long does it take to obtain an exceptional transport permit?

For Croatia, permits are usually issued within 3–7 working days. For international transport, permits must be coordinated for each transit country, which can take 1–4 weeks depending on the route.

What types of oversized cargo do you transport?

We transport industrial machinery, energy equipment, construction structures, ship sections, bridges, reactors, transformers and other indivisible loads that exceed standard dimensions.

Which countries do you cover with special transport?

We run oversized and heavy transport from Croatia to and from all EU markets, with the most frequent corridors towards Slovenia, Austria, Germany, Italy, Hungary, Czechia, Slovakia, Poland and the Benelux countries, plus the Western Balkans.

What information do you need for a special transport quote?

Send the cargo dimensions (length, width, height), weight, centre of gravity, lifting or loading points, the exact pickup and delivery addresses, and the desired time window. Drawings or photos speed up the route feasibility check considerably.
