The Caterpillar 320 Next Generation Hydraulic Excavator weighs around 25 tonnes depending on country of purchase.

It is used for earthmoving, roadwork, and material handling operations.


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

The review model had no missing parts or defects.

A mini catalogue of the Diecast Masters range is included.  A simple instruction sheet describes how the operator can be inserted in the cab.


The undercarriage is mainly metal with a plastic baseplate.   The tracks are metal with triple grouser shoes.  They are mounted on decent track frames with static rollers, and there are a couple of tiny graphics on each frame.

The cab has got a plastic mirror and a separate wiper is attached to the cab structure.  There is a metal grab rail and the plastic roof has a window.  Inside the detail is very good with Cat on the seatback and also on the left control console.  An operator wearing bright high visibility clothing can be fixed in the cab. 

The body casting represents the body shape very well and the side grille is formed by graphics.  The Cat graphics are very sharp and there are some tiny warning signs.    On top the engine cover is plastic with more graphics used as grilles.  The colour match on the engine cover is slightly off to the metal parts. There are also two equipment posts. There are textured walkway surfaces and the handrails are metal with a plastic mirror.

Soft hydraulic lines run to the boom and silvered connectors are modelled. More pipes and hoses run to the stick and again the connectors are modelled. Rivets on the boom, stick and tools are painted and there are small graphics on the stick.

The metal bucket is a nice casting with sharp teeth.  The quick connector is modelled but was non-functional on the review model.


The tracks roll easily, and they are mounted on spring-loaded idlers to maintain tension.

It rotates well.

The boom and stick have a good range of movement, and the bucket movement is reasonably good too.  It is a little short of the movement possible by the real machine at the extremes.

The operator can be installed in the cab for when the model is posed digging, or the cab can be empty to represent the machine being parked up or transported.


It is a robust model with a high metal content.

The paint is good and the graphics are sharp.


It is reasonable value.


The model is beautifully presented.  It looks good with small graphics adding detail.  The removable operator gives more flexibility when displaying the model.


The model became available in May 2018.
