Comment on this model.

The Liebherr HTM 804 Truck Mixer is an 8m mixer and this version is fitted with a conveyor that can distribute concrete up to 16.2m from the discharge point of the truck.  The conveyor is rated at 70m/h and can also take the output from other truck mixers discharging into the hopper.

It is in the colours of Meichle + Mohr, a German company formed in 1924.


Unusually for a Liebherr model it comes in a plain NZG branded box which presumably indicates it is no longer in the Liebherr model programme.  It is securely held within a couple of expanded polystyrene trays.  The review model had a broken conveyor piston but a replacement was provided and easily fitted.

No information is provided about either the real machine or model and the model requires no assembly.


Underneath, the 8x4 chassis has transmission detail with prop shafts and differentials, and suspension on the rear axles.  The tyres are the same on all axles and the wheels are detailed.

The cab is a Mercedes Actros and the headlights have excellent lenses and the door handles are modelled.  A pair of air horns, aerials and rooflight are on top.  Interior cab detail is plain but the graphics outside are very good and the Meichle + Mohr liver is interesting and nicely applied.

Behind the cab there is a plastic exhaust and other equipment and further back the wheel arches are metal.  At the rear the light clusters have plastic lenses.  A pair of small stabilisers have visible screw threads rather than smooth pistons.

The mixer drum is metal and the water tank and drive motor are well modelled in metal also.  The drum has intricate and colourful graphics applied.  At the rear there is an access ladder up to the entry chute and all parts in this area are metal with just the handrail and ladders parts a little thick.  Spare chutes are carried on the truck although these are fixed in position and cannot be added to the main discharge chute. 

The conveyor arm is another piece of all metal construction with some fine detail.  The conveyor belt is represented by being painted black.


The front axles are linked together and steer in tandem and there is a good range of movement.

The mixer drum is free rolling and spins very smoothly. 

At the rear there is a fold down access ladder and the two screw down stabilisers can be lowered. 

There is a rotating chute which takes the discharge from the drum. 

The conveyor gantry rotates and is articulated in three places so can be stretched out and posed in a number of ways without noticeable cylinder bleed.  Unfortunately the scaling between the discharge chute and the conveyor hopper is tight so it is a little difficult to pose the model correctly with the chute in the hopper, but it can be done. 


It is high quality model with a high metal content.

The very good paintwork and graphics make it an attractive item.


The model is good value.


This is an unusual truck mixer model and even more so because of the paint scheme.  It is a nice looking vehicle.


The model first appeared at the Nuremberg Toy Fair in February 2006 in an earlier version as model #652.  This later version of the model was made in a run of 300 models.
