This model is a Mercedes-Benz Arocs 4x2 with a six axle Goldhofer trailer. 

This model is in the colours of Sennebogen.  It represents a real truck, although the one shown on the box is an Actros with Meusburger trailer. Also the number of axles on the real trailer is not shown, and given the tractor is only a 4x2, it may be less than the six modelled here.


The model comes in a high quality Sennebogen branded box which holds the model within black foam. 

The review model had no defects or missing pieces.

Assembly is limited to attaching door mirrors and roof aerial to the cab, and adding the ramps into the storage box.


The tractor unit is a 4x2 Mercedes-Benz Arocs.  Underneath, the transmission and suspension components are detailed in plastic, with the steering functionally modelled.  The tyres are mounted on good looking wheels. 

The cab has a beacon light bar on the roof, and the Arocs grille looks convincing.  Number plates are included, and the Sennebogen graphics are reasonably sharp.

Behind the cab the wheel arches on the rear wheels are plastic, but there are no coiled lines.  The rear lights have plastic lenses. 

The trailer is almost all metal.  Detail underneath is fairly simple with the structure represented well, and with hydraulic tanks for the self-raising axles.  At the front end there are two plastic landing legs, and there is a further pair at the back for use in conjunction with a pair of loading ramps. 

The ramps are stored inside a holder forward of the first axle.  There is also a pair of pull-out width markers under the gooseneck. The gooseneck has a metal headboard arrangement and a spare wheel and there is a simplified console arrangement. 

The main trailer deck is all metal with the wood insert panels painted on.  Various tie down points are represented within the casting but are not useable. Plastic deck width extenders are modelled.

A set of metal deck posts is included.


The tractor steering works very well, and a very hard lock can be obtained if desired. 

The cab does not tilt. 

Counting from the front of the trailer, axle 1 steers independently, and axles 3 to 6 have linked steering which acts proportionally.  All axles have a degree of vertical movement as suspension, and axles 1 and 2 can be raised and clipped out of service although the range of movement is small.

The landing legs on the trailer can be pulled out and lowered at both the front and the back. 

The width markers under the gooseneck can be pulled out and retracted.

A pair of ramps is stored within a holder and they are accessed by an opening flap on each side of the trailer.  The ramps can be inserted into grooves at the rear for loading mobile equipment.

The gooseneck can be angled using the very stiff hydraulic cylinders modelled. 

The trailer is extendible, and there is a travelling transverse beam which can be positioned to support a load. 

Pull out deck width extenders are provided but there are no spanning deck sections supplied with the model.

Deck posts can be installed.


This is a reasonable quality model which is robust. 

The paintwork and graphics are mostly very good.


The model is moderate value for the quality and features offered.


This is a nicely presented model for Sennebogen.  The trailer is an old casting so the detailing is not up to modern standards, but overall it is a typically solid Conrad model.


The model was introduced at the Bauma Exhibition in April 2019.
