Comment on this model.

The Liebherr R 9100 is a mining excavator which has an operating weight of 108.5 tonnes in backhoe configuration.  It is optimised for loading trucks in the 50-100 tonne range and has a bucket capacity of 6.8m³.


The model comes in a Liebherr branded box.  The review model had no defects or missing parts.

No information is provided about the real machine or model.  Assembly is simple and is limited to adding a mirror and ladder.


The metal tracks are strong and have bolt heads just visible on the pads.  They are mounted on track frames which are a good representation of the real machine but without working rollers.  There is no other real detail underneath the model.

The operator's cab has darkly tinted windows however some interior details are still visible.  The main windscreen wiper consists of applied graphics and there are lights on the front but no local mirrors.  Outside the cab there is a nice mesh walkway with realistic metal handrails.  A plastic access ladder fits to the side which is different to the ladder arrangement usually seen on the real machine.

The body casting is good with some very nice grilles on each side and the graphics are very sharp.  A couple of video cameras are modelled in plastic.  The inside of the body looks good with a mesh platform and plastic hydraulics equipment.  Hoses run to the boom foot, and there are hoses and pipes on the main boom rams.  Lifting eye shapes are modelled on the counterweight but without holes.

The gooseneck boom has some very good hydraulics consisting of plastic pipe arrays and hoses.  It has lights but the lifting eyes are not modelled.  The short stick is modelled well and includes lifting eye shapes, but without holes.

The bucket is large and is a detailed single casting.  The teeth are good.


The tracks are tensioned by spring-loaded idlers and roll well on a rougher surface.

Rotation of the body is very smooth with no rocking.

The boom, stick and bucket have a good range of movement with cylinders that are stiff enough to hold any pose.

The access ladder slides up and down.


As expected this is a very solid model from Conrad with a high metal content.

The paintwork is good, and the applied graphics are very sharp.


It is good value for a relatively larger excavator model.


After a considerable gap it is good to see a new model of a Liebherr mining machine.  It looks good and has some nice detailing.  It would have been nice if it could strip down to make transport loads but overall it is good enough to be highly recommended.


It was first seen at the MinExpo exhibition in September 2012.
