The Tadano AC 7.450-1 is a 450 tonne class all terrain crane.  It has a main boom length of 80m.


The model has high quality packaging with an outer shipping carton enclosing a large Tadano-branded box.  The model parts are wrapped in soft paper and held within expanded polystyrene trays that are clipped together.

The review model had no defects or missing parts.

The build manual for the model has an excellent parts list, and it is very comprehensive with clear steps describing the assembly and features. 

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


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 detailed wheels with different hubs on driven and non-driven axles.  

The driving cab has a chain for hitching the hook whilst travelling.  Door mirrors, windscreen wipers and beacon lights complete the external detail. 

Behind the carrier cab the engine area has textured surfaces and grilles, and various exhaust and other components modelled. 

The outrigger assemblies are metal with chevrons and tiny graphics, and circular pads. Metal spreader plates are included and they 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 towing hitch.

The crane cab has a diamond plated access platform outside and the interior detail is excellent with a computer console. 

Small warning graphics enhance the detailing around the crane.

The counterweight tray has useable lifting points and the winch for the luffing gear for the fly jib is wound with rope.  The counterweight slabs also have useable lifting points.

The main boom ram has metal parts.  Detailing on the boom includes a spooling drum and the collars at the end of each section are particularly good.  

The inner telescope sections have a realistic profile with thin walls, and the overall boom geometry is excellent.   At the boom head the sheaves are metal, and painted white. 

The SSL is well made and is nearly all metal. 

One large hook block is included and it has three sheaves.  A Tadano-branded load plate is also included.


The axles steer independently and reasonable angles are possible.  All steering modes of the real crane can be realised. There is sprung suspension on each axle. 

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

The outrigger beams can be extended and pads lowered, with the crane able to be supported wheels-free, and the outrigger beams remain reasonably straight.

The operator's cab can be tilted to a good angle, and there is a slide-out access platform.

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 ram is by means of using a key to tighten grub screws and this works very well.  

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

A key is used to operate the main winch and it has a positive brake system.  The hook on the hook block has a full range of movement.

The SSL works well with the SSL winches being ableh to provide reasonable tension on the boom.  Foldable access platforms on the SSL system provide work platforms for tying off at the boom top during rigging.

The crane can be displayed in a couple of transport modes, either with or without the SSL attached.


This model is well made and high quality. 

The paint finish is very good, and the many small graphics are sharp.


It is reasonable value for a large crane model.


IMC has produced a very nice model of the AC 7.450-1.  It is an excellent combination of details and features, and will look attractive in company colour schemes.


The model was released in Q3 2022.
