The Liebherr R 940 Demolition Excavator was introduced in 2020.  It has an operating weight in the range 49 - 64 tonnes depending on configuration.


The model comes in a high quality Liebherr-branded box which opens up to reveal the model packed within expanded polystyrene trays. 

There were no missing parts on the review model. A handrail was detached during shipping and was easily refixed.

A simple instruction sheet is provided which describes the assembly of the storage racks, but it does not describe any of the features of the model.  The method of assembly of the storage racks means they can be difficult to dismantle to put back in the box. 

There is no information about the real machine.


The undercarriage has detailed metal tracks mounted on detailed frames which include plastic steps.  There are no working rollers.

The body is metal with casting details including panel handles.  The counterweight has the Liebherr name embossed on it and smaller details include a video camera at the rear. The graphics include the Liebherr name and small warning signs.  The hand rails are thin metal and strong,  and the roof details include a plastic air intake, and an exhaust pipe.  A bank of hydraulic hoses run to the boom.

The cab has a non-textured access step and a plastic grab rail with a non-silvered mirror.  The windows have the seals marked.  A large plastic debris guard covers the roof and windscreen.  Internal detailing is good.

The boom foot has excellent hydraulic detailing and the main lift cylinders have hoses running to them.

The demolition attachment is in three pieces, and is modelled in metal.  The hydraulic detailing continues the high standard with plastic pipework running up the boom top, and soft hoses run to the hydraulic rams and the quick coupler.   The quick coupler is plastic.

The crusher is also plastic, with a very good colour match.  A sorting grab is also included which is metal and has small hydraulic cylinders modelled inside.

The metal storage rack for the demolition attachment is modelled well and includes ladders and platforms. 

The separate excavator boom and arm also has very good hydraulics detailing.  It has a large detailed bucket, and also comes with its own metal storage rack.


The tracks roll well on a rough surface and are tensioned by springs in the idlers.  The track frames are retractable so can be posed in working or transport configurations.

The model rotates well.

The cab tilts to a good angle and it holds any pose well.

The demolition attachment has a good range of movement and it is stable even when the whole assembly is horizontal.  There is a small plastic clip which fixes the booms together for stability during transport.  The quick coupler allows either tool to be fixed with a pin. 

The crusher rotates and opens and closes also.  The jaws are spring loaded so they will grip to a degree.

The sorting grab rotates and opens and closes with the two sides linked together so that they move in unison.

The excavator boom can be attached to the boom foot in two different positions using a plastic pin.  It has a good range of movement on all rams.

The provision of storage racks allows the model parts to be posed as interesting transport loads.


The model is strong and robust with a high metal content. 

The paintwork and graphics are very good.


The model is decent value overall.


The R 940 is a very good looking and functional model.  It is a typically robust Conrad model which can be posed as transport loads or in an operating mode.
