The Demag AC 700-9 is a 700 tonne class all terrain crane.  It has a main boom length of 60m, and a maximum system length of 149m.

This version of the model is the colours of Mammoet, the Dutch lifting and heavy haulage specialist.  It is the Collector's Edition of the model.

It has Mammoet model number 410233.


The model comes in high quality packaging with an outer shipping carton enclosing a large Mammoet-branded box.  The model parts are wrapped in soft paper and held within expanded polystyrene trays that are clipped together and not taped.

The review model had no defects or missing parts.

This edition of the model comes with a book describing the development of the real crane and it has many excellent photos.  There are some technical details too although some more configuration and load chart information would have been interesting too.  The build manual for the model is very comprehensive with clear steps describing the assembly and features, and only reeving diagrams for the hook blocks are missing.  There is an excellent parts list.

Tools are supplied to assemble and operate the model, and many of the bags of small parts are numbered making it easier to follow the instructions.

The Collector's Edition also encloses an engraved key chain fob with the unique number within the production run.   Also included is a Mammoet AC 700 key chain.


The chassis is highly detailed with the transmission and steering present although not all parts are physically linked.   The tyres are very good with a fine tread pattern and they are mounted on nicely detailed wheels.  

The driving cab has a rope for hitching the hook whilst travelling, and other details include a nice grille at the front and a tiny graphic in the side windows.  Door mirrors, windscreen wipers and beacon lights complete the external detail. The seat backs have a Terex logo on them which may reflect the real crane that Mammoet owns.

Behind the carrier cab the engine area has textured surfaces and a nice mesh grille, and there is a highlighted filler cap on a tank.  The exhaust pipe has a hole in it.  The sides of the carrier have highlighted bolt heads and tiny graphics to give an authentic look, including a Mammoet fleet number.

The outrigger assemblies are robust and well made.  They are metal with chevrons and tiny graphics, and circular metal pads can be clipped on for storage, or used together with metal spreader plates which have useable lifting lugs.  The outrigger pistons have smooth faces.

At the rear of the carrier the lights have plastic lenses, and there is a realistic number plate.

The crane cab has a diamond plated access platform outside with metal handrails and the interior detail is excellent with a busy computer console.  Small graphics enhance the detailing around the crane.

The counterweight tray has useable lifting points and the winch and luffing gear for the fly jib is reeved up in the factory.  The counterweight slabs also have useable lifting points.

The main boom rams are excellent metal parts with thin white lines.  Detailing on the boom includes a couple of spooling drums and access platforms, and the graphics are high quality.   Pendant bars for the Sideways Super Lift (SSL) can be stored for transport.  A ladder can also be hung at the front.

The inner telescope sections have a realistic profile with thin walls, and the overall boom geometry is excellent. There is a Mammoet graphic on the top boom section.  At the boom head the sheaves are metal, and painted white.  Hoist rope tying-off points are modelled.

The SSL is well made and is nearly all metal.  Only the hoist guide rope part seems a little awkward on the model.

Two hook blocks are included, 3 sheaves and 7 sheaves, and they are very good metal parts.  Also included are sets of lifting chains and these are welcome additions to a crane model.  They can be used particularly when the crane is self-ballasting.  A Mammoet-branded load plate is also included.

This edition of the model also includes holders for carrying various parts during transport. These are metal frames and they are another welcome addition to a crane model.


The axles steer independently with the exception of axle six which is fixed as per the real crane.  The achievable angles are very good.  The crane can also be posed with crab steering if required by raising axle six out of service and this works well on the model. There is sprung suspension on each axle. 

Handrails can be added to the crane body when in working mode.

The outriggers can be extended and pads lowered, with the crane able to be supported wheels-free, and the outrigger beams remain reasonably straight. The beams can be locked in their folded out position.

The operator's cab can be rotated from the transport position and raised to provide clearance when the crane slews.  It can also be tilted to a good angle.

The counterweight system can be fitted in various configurations, including being mounted on the carrier deck during self-assembly.

Raising the boom is easy as the locking mechanism on the main boom rams is by means of using a supplied key tightening screws and this works very well.  

Telescoping the boom is smooth and easy with a spring clip to lock each boom section.  It has locking positions at 45%, 90% and 100%.

A key is used to operate the main winch and it has a positive brake system.  Access to the winch is enabled by a removable panel held in place by magnets, and this is a high quality solution to avoid unsightly holes in the crane body.

The SSL works well with the SSL winches being stiff enough to provide reasonable tension on the boom.  Foldable access platforms on the boom provide support for the SSL top sheaves.

The crane can be displayed in a variety of transport modes from the lightest configuration (no front outriggers and no SSL), to fully loaded.   Various parts can be carried on the supplied trays on a suitable truck.


This model is well made and high quality.  It is beautifully presented.

The paint finish is slightly thick in places but overall  very good, and the many small graphics are sharp.


It is good value, with the additions in the Collector's Edition being worthwhile.


This is an excellent version of the Demag AC 700-9. It looks great in Mammoet colours.  The book and carrying frames in the Collector's Edition are top notch.


The model first appeared as a Collector's Edition in Mammoet livery.  The Collector's Edition in Demag livery was released in December 2019.  A standard edition without the book and other parts was also released.
