Comment on this model.

This model is a Liebherr 43 R4 XXT Concrete Pump mounted on a Mercedes-Benz Arocs 8x4 chassis. 

The maximum concrete output is 163m per hour and it has a horizontal reach of 38m and a vertical reach of 42m.

Packaging

The model comes in an Liebherr branded box with a window. 

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

There is no information about the real machine or the model.  Separate parts included are the hopper cover and pins for the hydraulic rams on the boom.

Detail

Underneath, the chassis is fully detailed in metal with only the steering linkages being modelled for functionality rather than detail.  The tyres have a decent tread pattern and are the same on all wheels.

The cab has horns and aerial on the roof, and another small aerial and a plastic grab rail on the driver's side.  The door mirrors have some texture and the distinctive Arocs grille is modelled with a realistic appearance.  There is a dummy number plate front and rear. 

Inside the cab, the seats have arm rests.

The carrier body has a metal structure, with the handrails and concrete pipe being plastic, as are the rear wheel arches.  There are textured walking surfaces and the wheel arches are metal throughout.  The lights at the rear are painted.

The hopper is metal with a plastic grille and a metal cover.

The front outriggers are two stage in metal and the larger rear outriggers are metal also.  The pistons have visible screw threads, and the spreader plates are cast in to the rear of the truck chassis and are not removable.

The boom sections are metal with details in the casting, and the pipework is plastic.  The plastic ram jackets have a reasonable colour match.  The connection rivets are discrete except for the one at the boom foot.

There is a plastic discharge hose at the end.

Features

The truck rolls well and the front two axles have linked steering which can be posed to a very good angle, although the tyres foul at the extreme.

The outriggers fold out and the front ones telescope.  The pads can be lowered by unscrewing.  The model can be supported wheels free.

At the rear the hopper can be posed either open or closed although it is not hinged - it has to be plugged in which does not work as well as a hinge. 

Within the truck deck there is an opening hatch which provides access to the main pistons of the concrete pump.

The boom rotates smoothly.

The boom articulation works well and the rams were able to hold almost all poses.  Pins are supplied with the model to insert in the rams if required.

Quality

This is a heavy and fairly robust model which gives it the feeling of quality. 

The paint and graphics are very good.

Price

It is fair value for a concrete pump.

Overall

Liebherr bought the German pump maker Waitzinger in 2012, and this model is derived from an earlier NZG Waitzinger model.  It looks good.
