Comment on this model.

The Liebherr R 936 is a crawler excavator designed for civil engineering applications.  It has an operating weight in the range 30-35 tonnes and it typically uses buckets of size 0.70 - 1.75m³.

This model is in the colours of Korz, a German company based in the Rhineland.


The model comes in a typical Liebherr branded box.  Inside the model is wrapped in soft paper and rests in a polystyrene tray. 

There were no missing parts or defects on the review model.

There is no information about the model or the real machine.  It is fully assembled, and NZG also provides some spare track links and pins.


The underside of the body has some detailing and the track pads are metal with bolt heads and grousers.  They are mounted on track frames which have some fine casting details and also working rollers.

The cab has very thin metal grab rails and windscreen wipers and the windows have detailed frames and seals.  There is also an aerial and mirror.  It looks very good inside with the joysticks and levers being highlighted in black.

The curved body is cast well and the engine cover is top notch with detail in the casting and tiny hinges highlighted with silver paint.  The grab rails are metal and other details are carefully painted.  At the rear the exhaust pipe is solid without a hole. At the boom foot there are many soft rubber hydraulic hoses which give a complex look.  The Korz colour scheme and graphics are very attractive.

The hydraulics on the boom are modelled really well with silver pipes indicated on the boom and cylinders, and more soft hoses.  The rivets used are painted and small so the look is realistic. 

The bucket is a good casting with nice teeth and the quick hitch facility is modelled effectively.


The tracks were very stiff on the review model but can be turned by hand.

The model rotates well.

The movement of the boom and stick is very good although the boom is possibly a bit restricted when digging deep.  There is a pleasant stiffness in the cylinders. 

The bucket is removable and can also be reversed.


This is a high quality model with a very good finish and the metal content is high.

The paint and graphics are excellent.


The model is good value given it is a limited edition.


This is a great looking Liebherr machine in the colours of Korz.  As with other versions of the R 936 the detailing and features are very good.


The model first appeared in Liebherr colours at the Nuremberg Toy Fair in 2012.
  This version of the model was a winter 2014 release in a run of 300 models.
