This is a model which reflects a historic move of a 1500 tonne reactor in Lithuania by Mammoet. 

It consists of the transport, with the reactor available as a separate model.

Packaging

The model comes in an outer shipping carton which contains a Mammoet-branded box which has a photo of the reactor move.  Inside the box the model parts are held in separate high quality boxes with the parts wrapped in soft paper.

The review model had no defects or missing parts.

A uniquely numbered Mammoet certificate is also included, together with useful instructions which also has a parts list. 

Detail

The Arocs has a detailed 8x4 chassis. The transmission components are modelled and the tyres are different on the steering and driven axles. The wheels are very detailed and the hubs are highlighted in red. 

The cab has  air horns on the roof together with a nice light bar. The Arocs grille is impressive and has an accurate license plate.  The many graphics are very sharp and there is a fleet number on the cab.  There is a towing hitch at the front.

Behind the cab there is an impressive equipment tower and a toolbox, with a thin metal ladder on one side.  At the rear the lights have lenses and the rigid mud flaps have graphics applied. 

A driver is included as a separate part.  It is detailed, with Mammoet printed on the back.

The ballast box is a plastic part which is very well finished.

Twelve 6-line Scheuerle K25 modules are supplied, and they are detailed to the same level with a high point being that they each have individual fleet numbers.

The rubber tyres have a realistic tread pattern and they are mounted on metal hubs.  Each pair of wheels is mounted on a metal support with a functioning hydraulic cylinder. The structure underneath is strong and robust. The edges of the modules have a yellow stripe.  

Plastic connectors enable the modules to be linked at the sides and ends, with the pinning mechanism of the real modules also utilised.  The pins are mounted in a holder like the real module. Nicely textured plates fit into the module surface.

Four power packs are included and they are mainly metal and nicely detailed.  There are very good etched grilles and a nice exhaust pipe. 

Drawbars and steering connections are provided and they have individual fleet numbers.

The turntables and spreaders are plastic parts and graphics add some detail.

Features

The Arocs has decent steering movement. 

A separate fifth wheel is provided so the tractor can accommodate trailers with a larger kingpin.

The cab has opening doors.  These work well, and open to a moderate angle.

The driver can be inserted in the cab.
 
The modules have linked steering which is proportional, and with a good range of movement.  Steering of the assembled transport via the drawbar is not so good due to the tolerances in the complex mechanism.  Each wheel set has sprung suspension with decent movement. 

The modules can be connected in parallel and in series. 

The turntables rotate.

It looks great with the optional reactor as a load.

Quality

This is a high quality model with a high metal content. 

The paint finish and graphics are excellent.

Price

It is a very limited edition and large model, and is priced accordingly.

Overall

This is a super impressive heavy transport model, particularly when loaded with the separately available reactor.  It blends detail and functionality to produce an excellent model.

Footnotes

The model first appeared at ConExpo 2026 and was made in a run of 150 models.
