The Caterpillar 7974 AC Mining Truck has a payload of 297 Metric tonnes.  It is used for large quarry operations.

Packaging

The model comes in substantial high quality packaging.  There is an outer shipping carton which contains a tin which is protected by expanded polystyrene trays.  The tin is high quality and includes pictures and details about the real machine.

The review model had no defects or missing parts. 

A 2020 mini brochure of the Diecast Masters range is included, as is an instruction sheet for installing the operator.

Detail

This is a large heavy model weighing around 3kg.

The chassis construction is heavy with very good detailing which is a result of using plastic parts with an excellent colour match.  Many cables and pipes are  modelled and they give a complex appearance. Also modelled is a ladder inside one of the front wheels.

The large wheels are detailed and the tyres have a realistic matt finish and a detailed tread pattern. 

The front of the truck has an impressive radiator grille and the access stairs and ladders are plastic, but the handrails are metal and realistically thin.  There are two separate wheel chocks.  The level of detail throughout is high.

The cab deck is textured with a non-slip surface and there is an impressive cabinet with highlighted grilles and handles.  The radial grid on the right hand side has very nice metal mesh.  There are digital load indicators on both sides.  The cab is metal and the seats and controls are visible, and an operator can be installed.  Large mirrors on each side of the truck are plastic.

Between the wheels are large boxes and tanks which are modelled in plastic with enhanced detail, and with an excellent colour match.  Below the dump body the top of the chassis also has many details with various tanks and pipes modelled.   Two large two-stage hydraulic pistons lift the dump body, with the middle stage being light grey plastic which does not look so good.  Large soft mud flaps look good.

The dump body is a large metal casting with some plastic elements. Sharp graphics are applied and lifting eyes are formed but are not complete holes.

At the rear end a couple of bars hang down between the rear pairs of tyres to clear out trapped material and a safety cable is modelled.  The detailing at the back is excellent including detailed graphics on the suspension cylinders and intricate highlighting of the rear axle.

Features

The front wheels steer although the range of movement is moderate. 

The rear axle suspension works well.

At the front the access stairs at the bottom fold down to enable an operator to board the truck.  A ladder on the opposite can be folded down.

There are two opening gates at the top of the ladder and stairs.

The dump body tilts well to a decentt angle and the cylinders are stiff enough to hold the body at any angle.

On the cab deck an access flap can be opened to enable the engine to be seen. The cab has opening doors on each side. 

The operator can be installed, or left out.

Quality

It is a high quality model with significant metal content and appropriate use of plastic.

The paint is very good and the graphics are sharp.

Price

It is a very large model which is fully priced.

Overall

This is another well presented model by Diecast Masters.  It is impressive with many nice details, and poses well with a suitable mining excavator.
