Hamm is part of the Wirtgen Group of companies.  The Hamm GRW 280 Rubber-wheeled Roller is a flexibly ballasted road roller with an operating weight ranging from 10 to 28 tonnes depending on the amount of ballast installed.  The machine has an asymmetric wheel arrangement to provide uniform compaction.  The GRW 280 series rollers won the iF design award in 2010.

This is a model of the open version of the machine with a Roll Over Protection Structure (ROPS).


The GRW 280 comes in a Hamm branded box, and it is held within two expanded polystyrene trays, and wrapped in soft tissue.

There is a little information about the real machine on the box sleeve and a small leaflet describes how the canopy is fitted to the model which only takes seconds.  Two spare mirrors are also included which is a nice touch.


This is a compact model with a nice weight.  Underneath, the detail is simple with the ballast blocks denoted by colour difference.  The wheels have smooth tyres mounted on metal hubs and each pair has a scraper for removing material from the tyres.

The lights at the front and rear are very good with plastic lenses giving a realistic appearance.  On each side there is a plastic mirror but they look convincing, and the handrails are metal and pleasingly thin.  There are textured steps and walking surfaces.

The operator's console is great with a nice seat and controls and the computer screen is replicated with tiny coloured graphics.  The real machine has sight lines for the operator down to the tyres front and rear and it is an excellent detail that these have been replicated accurately on the model.

The canopy is a simple plastic piece, whilst the Deutz engine is very detailed with pipework and different coloured components.


The rubber tyres roll well although the scrapers can sometimes act as a brake when going backwards.  The wheel scrapers can be lifted from the tyre surface.

At the front the wheels steer as a linked pair with reasonable movement.  Each pair also has suspension modelled with a spring although there is no actual 'springiness' in the mechanism. 

The operator's console rotates right and left and also slides across the cabin floor.

At the rear the engine cover opens widely to reveal the detailed engine.

The canopy can be added and removed as desired.


This is typically high quality offering from NZG.  Both the paintwork and graphics are very good.


It is good value.


The Wirtgen range of models aims to achieve a high standard and this model of the GRW 280 hits the spot and is highly recommended.


The model first appeared at the Nuremberg Toy Fair in 2011.  A version of the model with an enclosed cab is numbered NZG 832
