This model is a Putzmeister Pumi 25-4 truck mixer concrete pump mounted on a Mercedes-Benz Arocs 8x4 chassis. 

This model has been given an 'L' series designation in the Conrad numbering system which indicates reduced functionality.

Packaging

The model comes in a Conrad branded box with the model protected by a foam rubber insert. 

The review model had no defects and no missing parts. 

There is no information about the real machine.  The assembly required is fitting door mirrors and a roof aerial.

Detail

The chassis detailing at the rear has the axles and suspension modelled in plastic, and at the front the steering is modelled in a functional way.  However the drive shaft between the engine and the rear axles is missing which is a modelling compromise.  The wheels look very smart and the tyres are the same on each axle. 

The cab has an aerial on the roof, and the lights at the front have plastic lenses.  There are Putzmeister graphics at the front, and the Arocs grille looks good.   Inside the cab details are simple.  The mirror built in to the visor and the small door mirror are both unsilvered.

The rear wheel arches are plastic, and at the rear the lights are painted.  The rear stabilisers are modelled, but they are not functional.

The mixer drum is metal with a plastic ring at the rear bearing, with simple graphics.  The drive motor and water tank at the front are also metal as is the access platform at the rear although the handrails are thick. 

The hopper and chute are plastic and there is a fixed plastic chute extension above the rear wheels.  There is no grille in the hopper and the lid is plastic.  The rear access platform and ladder are in metal.

The placing boom is a strong part made of metal as is the pipework.  Nice Putzmeister elephant graphics are across the boom sections.  There is a plastic hose section at the end of the boom.

Features

The front axles have steering and it is not linked, presumably because of other chassis details.  The model can be posed with a reasonable lock on the steering.

The rear driven axles have a degree of vertical movement to simulate suspension.

This model does not have a tilting cab.

The drum turns smoothly without being free rolling, and the rear chute can be angled across the hopper.

The outrigger beams can be pulled out and the pads lowered by unscrewing the visible screw threads.

The placing boom is fully articulated with stiff rams so any pose can be set.   It can be rotated fully.

The hopper has a sliding lid which is a little fiddly to position properly.

Quality

It has a high metal content and feels robust. 

The paint and graphics are to a good standard.

Price

The model is reasonable value.

Overall

This is a relatively heavy model with a quality feel.  It is an 'L' designation model under Conrad's numbering system so it has a lower functionality, but it remains a nicely implemented model, if not the most detailed.

Footnotes

The model was a Bauma 2016 release by Conrad.
