The CAT 772 Off-Highway Truck is a smaller sized dump truck.
CAT style box.
Looking at the rear end.
Underside view.
Good ground clearance as would be expected.
Transported on a Nooteboom Euro-99-24 Low Loader.
The CAT 772 is a nominal 50 ton (45 tonnes) class machine with a payload of 41yd (31m).  It has a top speed of almost 50mph (80km/h), and the unladen weight is around 90,000lbs (35 tonnes).


The model comes in the usual Caterpillar-style windowed box, with the model securely tied down to the base and therefore the usual fight is required to free it.  The review model had no defects or missing parts, and is fully assembled out of the box.

There is no information provided about the real machine.


The tyres have a good tread pattern and are not too shiny so they look like new tyres rather than something false.  They are mounted on hubs which have good detail.  The detail underneath is quite good too, with drive shafts and suspension components visible.  Behind the front wheels large mud flaps are modelled in plastic.

The cab is fine, with interior detail and a windscreen wiper on the outside.  There is plenty of handrailing around the cab although it is plastic and therefore not of the finest quality.  Mirrors are provided, and the lights at the front are simply represented.

The dump body is cast well with a good representation of structure.


The steering is functional although the lock is constrained by the plastic mud flaps, so a good hard lock cannot be posed. 

The rear axle has a very limited degree of suspension movement which may be more due to model tolerances than being a designed feature.

The dump body tilts, but the range of movement is very severely limited, which is a very strange modelling compromise and it is not clear why it was necessary.


This is a reasonable quality piece from Norscot.  The paint and graphics are very good.  There is an amount of plastic on the model, but on the whole the truck looks good.


The model is reasonable value for the price.


The CAT 772 is an unusual sized truck to be modelled, and many collectors will be interested in it for that reason.  Although it looks good, the features let it down a little, particularly the tilting dump body with its very limited angle.


The model first appeared in 2008.  A 1:87 version of the 772 was introduced at the end of 2010.

The handrails are plastic and do not sit quite straight but they can be gently flexed.
The dump body tipped to its maximum angle which is way less than the real machine can achieve.
Cab details.
Nice hub details.
Being loaded by a Caterpillar 323D which is a little small for it.
