The Liebherr R 9150 B Mining Excavator has an operating weight of 130 tonnes and is designed for use with mining trucks in the 50 - 135 tonne range.


The model comes in a large standard Liebherr box design with the model held within two separate expanded polystyrene trays and protected with clear plastic sheets.

There were no missing parts or defects on the review model, other than a tiny handrail which was separated during shipping and was easily refixed.

There is no information about the real machine or model. 


The undercarriage has branding on the base plate and there is some panel detailing under the body of the machine.

The track frames are detailed and there are working rollers on top with solid non-functioning rollers on the bottom.  The  drive sprockets appear to be metal, and there is an excellent access ladder with textured steps and tiny thin handrails.  The metal tracks are nicely formed and equate in scale to a 750mm width on the real machine.

The cab is metal with a plastic windscreen guard and mirrors.  Lights and window seals are detailed well, and Liebherr can be seen printed on the seat back through the tinted windows. 

Outside the cab the walkways have an excellent mesh flooring and the handrails are metal.  Steps also have coloured edging.  Moving around the body the panels are well defined in the casting and there are many small graphics adding to the detail.

The counterweight has the Liebherr name embossed and on top there is a video camera and highlighted lifting eyes. 

The engine compartment has a cover with excellent mesh grilles at the rear, and there are nice twin exhausts.  Air intakes sit on top.

In front of the engine compartment the detailing is excellent with a mesh floor, small graphics and many hydraulic hoses.  There is also an excellent fan enclosure.

The boom is an impressive piece of modelling. The hydraulic rams have hydraulic connections and the hoses and pipework are first rate.  Lifting eye positions are marked, and the lights have tiny protective grilles.  The stick is of the same high standard, and all of the connection pins look realistic.

The large bucket is eye catching with its large white teeth which are formed really well.  But there is small detailing as well including tiny graphics.


The tracks can roll easily, and work well on a rough surface. They are tensioned by spring-loaded idlers. 

The body rotates smoothly without any stickiness or rocking.

The movement of the boom and stick has a very good range overall.  The bucket movement is excellent.

The model cannot be configured for transport in any way, and the bucket is not removeable.


This model has a very high metal content and is very well made and robust.

The paintwork and graphics are generally excellent.


It is good value.


This is an excellent mining model from WSI.  Its major strength is the detailing and the quality feel.  The features perform well and the only thing it would have been nice to see is the ability to reduce the model into transport loads and have a removable bucket.


The model first appeared as a prototype at the Nuremberg Toy Fair in 2018, and was released at the Bauma Exhibition in 2019.
