This is a model of a Mercedes-Benz Arocs MP4  BigSpace tractor with a Broshuis 4-axle semi low loader. 

The model is in the colours of Wasel, a German crane and logistics company.


The model comes in a WSI Models branded box which has a window allowing the model to be seen. 

There were no missing parts or defects on the review model.

There are quite a few parts supplied for the trailer, but no instructions.


The tractor is a Mercedes-Benz Arocs 6x4 unit. It has a very detailed chassis, with the suspension and transmission modelled.  The wheel hubs are particularly nice, and there are different tyre tread patterns on the driven axles. 

At the front the Arocs grille is modelled well, and there is a realistic number plate.  There are beacon lights on the roof.  Behind the cab, there are coiled lines, and plastic wheel arches cover the rear wheels.

The trailer is highly detailed.  Underneath, the structure of the trailer is modelled well, with the axles having the suspension fully represented, and there are hoses running to each wheel.  At the front there are a couple of landing legs.  Rear legs for the loading ramps are modelled but are not functional.

The surface of the trailer is very good with the screw holes modelled in the replica timber deck.  Details along the edges of the trailer include a yellow stripe and the Broshuis logo.  On one side there is a control console box.

At the rear the lights are good and there is a number plate.

The gooseneck has a tool box.  Sides for a storage box are metal with Wasel graphics. 

A separate pack of metal deck posts is provided and also a support beam. The trailer width can be extended with boards and there are also parts for securing a container.

A pair of width markers attaches at the rear end of the trailer if required, and a couple of pull-out ones are stowed under the gooseneck.


The Arocs has a steerable axle with decent movement.  The model rolls well.

The cab does tilt but does not maintain a tilted pose.

The trailer has plenty of features.  All the axles have effective working suspension with good movement, and the rear two axles are linked with self-steering and can adopt a reasonable angle. 

At the front the landing legs can be screwed down, and the marker boards stowed under the gooseneck can be pulled out into position. 

The trailer bed can be extended to almost double its length.  For wider loads the trailer has a load floor width adjustment and this works with tiny extension beams which can be pulled out and then replica timber beams can be laid between them.

Other configuration options are provided by fitting or omitting the deck posts, and the same goes for the gooseneck side panels.  Locks for attaching shipping containers are also supplied, as is a transverse support beam.

Separate plastic loading ramps can be stored at the rear or can be placed to simulate loading.  Loading plates for the gooseneck are also included.


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

The paintwork and Wasel graphics look realistic.


The model is reasonable value.


This is a particularly good model to pair up with a crane in Wasel colours, and the trailer can be configured for many load options.


The model appeared in February 2017.
