The Caterpillar 785D Mining Truck has a gross vehicle operating weight of 250 tonnes, with a maximum payload of just over 140 tonnes.  Fully loaded, the truck can travel at 55km/h (34mph).

Another interesting statistic is that the fuel tank capacity is nearly 1900 litres (500 US gallons).


As with nearly all Caterpillar models, it comes in a windowed box with the model held tight between plastic formers.  Also it is tied to the base with stiff ties, so collectors can expect a short frustrating experience to free the model from the packaging.  With that said, the review model had no defects or missing parts.

There is no information about the real machine other than a photo on the back of the box (which has a different dump body style and tyres to the model), but there is a description of the main features of the model.


The tyres are made of that rubber that is slightly too shiny and a matt finish would probably look better.  The tread pattern is fine, and the hubs are quite good plastic parts with an excellent colour match to the rest of the model and with the fine detailing that plastic allows. 

Underneath, the truck has a heavy construction but there is a gap where the engine would be, so it is not realistic, although of course this will not normally be seen.  Plastic is also used for the tanks between the wheels, but again the colour match is excellent so it does not show. 

The front of the model is impressive with lots of fine metal handrails.  The ladders and stairs are plastic, as is the other equipment on the cab deck, and the main radiator grille at the front, but they all look good.  The driving cab is metal with some interior detail, and it also has metal grab rails and a windscreen wiper.  A pair of large driving mirrors are positioned on each side of the truck.  There is some nice small detailing such as the air horns below the driver's cab.

The dump body is a large metal casting with a good structure and it includes some plastic mud flaps and a non-functioning chain at the rear for securing the dump body open.  Also included are bars for removing debris between the rear tyres.


The steering works well and has quite a reasonable range of movement.

The rear axle has a good suspension mechanism which allows either independent oscillation or both wheels to move together.

The mirror opposite the driver's cab can be folded in for transport, but not the driver's side mirror.

The handrail at the top of the access stairs is hinged so it can be opened to provide access to the ladder.

The dump body can be tipped and the dual stage pistons open well and are stiff enough to hold any pose.  The tipping angle is realistic.


This model is well made and robust.  Plastic has been used thoughtfully and effectively without affecting the look of the model.  The paintwork and graphics are very good.


The model is quite large and so is good value.


The Cat 785D is a continuation of Norscot's improved quality of models in recent years.  The detail level is good with some of the finer points such as the metal hand railing adding to the quality feel.  It also poses well with a suitable loader.


The model first appeared in dealers in 2009.
