This Terex Franna AT-40 is a pick and carry crane with a maximum capacity of 40 tonnes.

This model of it is in the colours of Mammoet, the Dutch lifting and heavy haulage specialist.

Packaging

The set comes in a Mammoet branded box.  The model is held between a pair of trays and it is wrapped  in soft paper. 

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

There is no information about the model or the real machine.  A Mammoet Collector Card is included.

Detail

The underside is detailed with drive shafts running to the front and axle 2.  A plastic stabiliser frame is modelled between the rear axles.  There are different tyres front and rear and the wheels look good.

The front has paint highlighting of hinges and a good use of graphics to provide detail including a licence plate.  A lifting beam is attached at the front.

The windscreen has the unique shape to maximise the operator's view.  The cab doors have over-large hinges which detract a little, but the decoration is very good and includes a fleet number.  Interior detail is good.

There are tiny graphics at the pivot point but there are no hydraulic hoses crossing.  The deck edges have a yellow stripe and more tiny graphics.  The handrails are reasonably thin metal.  At the back there is a good looking radiator and the many graphics give a busy look.

The crane body has nice Franna graphics, and the hydraulic rams have a very good colour match to the metal parts.

The main boom section has very smart Mammoet graphics and there is a spooling reel.  Chevron graphics on the boom had a slight smudge on the review model.  The boom has a beacon light and there are metal sheaves in the boom top.  There is a significant modelling compromise on the telescopic sections in that they are solid and not perforated with holes like the real machine. 

The hook block is metal and there are fixed hooks for the boom top and the underside of each boom section.

Features


The model rolls well enough in site mode on axles 1 and 2, with axle 3 raised.  For highway mode axle 3 can be lowered but the wheels were stiff to turn on the review model.

Steering across the pivot point is very good and appears to match that of the real machine.

The cab doors open to a very wide angle.

The main boom rams are stiff particularly towards the maximum angle.  The telescopic sections extend smoothly.

The winch does not have a brake but there is enough friction to hold a light load.  Rope has to be put on the drum as part of the assembly and in practice it is difficult to get enough rope on the small drum to allow the hook to be fully lowered on four falls at maximum boom extension.

Fixed hooks can be deployed at the end of the intermediate boom sections, and at the boom top.

The lifting beam at the front can be unscrewed and used on the hook, but it does not have extendible sections due to the very small cross section of the beam.

Quality

It is a nice quality model with a high metal content.

The paint and graphics are generally very good.

Price


It is moderately priced for a limited edition model.

Overall

It is good to see this model of an unusual lifting machine.  It is generally well executed by Weiss Brothers and it looks very attractive in Mammoet colours.

Footnotes

The model was released in July 2025 in a run of 500 models.
