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 28t depending on the 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 enclosed cab version of the machine.


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 beacon light 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 cab detailing is good with wipers and a beacon light, and it is made of metal including all the grab rails.

The operator's console is great with a nice sat 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 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 on this cab version of the model is fixed in position.

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


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


It is good value.


This cab version of the GRW 280 is a nice model and is highly recommended.


The model first appeared at the Nuremberg Toy Fair in 2011.  A version of the model with an open ROPS is numbered NZG 8321.  A version in Kibag colours appeared at the end of 2012.
