The Demag AC 45 City is a 45 tonne class crane designed for city work.  It has a main boom length of 31.2m, and a maximum system length of 44.2m.


The model comes in a Demag-branded box.  The model parts are held within expanded polystyrene trays which are clipped together with plastic formers rather than being taped, so this is much nicer packaging.

The review model had no missing parts.  The alignment of the connecting holes between the fly jib and boom head was not good due to a workmanship issue.

The manual is very good.  It describes all aspects of the model, with clear instructions.  It mentions different length pins but in practice they are all the same length. Tools are supplied to operate the model.


The chassis is very good with the transmission and suspension fully detailed.   The tyres are also very good with a fine tread pattern and they are mounted on very nice detailed wheels.  

At the front is a hitching point for the hook whilst travelling, and there are nice lights, metal handrails and texturing. Tiny graphics add detail all around the carrier.

At the rear the engine area is detailed with metal and plastic parts.  Two fold down ladders are fixed to the deck.  A large mirror support has excellent silvered mirrors.

The outrigger beams are nicely formed with structural holes detailed.   The pistons have visible screw threads when the pads are lowered rather than smooth faces, and this may in part be a compromise driven by the thinness of the outriggers on the real crane. The pistons also cannot be fully retracted which is a pity.  Nice metal spreader plates are also included with the model.

The crane cab has rather large window wipers, and the interior detail is good although the steering wheel seems very large.  Small graphics enhance the detailing around the cab and there are work lights and a beacon light.

The counterweight is nicely decorated with chevrons and the Demag name.

The main boom ram is a metal part.  Detailing on the boom includes a couple of spooling drums, and the hoist rope winch is modelled well including a cage and hydraulic hoses and pipes.  The boom sections have a two tone decoration.  The pulleys on the model look very convincing.  They seem to be metal painted white to resemble the plastic pulleys used on the real crane.

A bumper for the boom head is provided for use in transport mode and it is a nice metal part.

A fly jib with swing away section is included.  It is metal throughout.

A single three sheave hook block is included and it is good.  The model really needs a separate smaller hook to complement the fly jib.  An optional Demag plate is provided to keep tension on the hoist rope.


The axles can steer independently with reasonable movement although with some springiness so they try to return to a straight pose which is a pity as the model would look good with the wheels posed having a hard lock.   There is sprung suspension on each axle. 

Ladders on the carrier deck can be rotated and lowered and this works really well.

The outriggers can be extended and lowered, and the crane can just about be supported wheels-free.

Raising the boom is easy as the locking mechanism on the main boom ram is by using a supplied key to tighten a screw and this works well.

Telescoping the boom is smooth and easy with a spring clip to lock each boom section at maximum extension.

A key is used to operate the main winch but there was not much brake action on the review model.

The fly jib can be attached and reeved in two lengths. 


This model is well made and very good quality.  The use of plastic is appropriate and done well. 

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


It is moderate value for a three axle crane.


This is a really good looking model of the Demag AC 45 City. The detailing makes for a high degree of realism, and the features work well enough in most cases.  It is also a very well presented model.


The model was first displayed at the Ede Model Show in 2019.  A version with small road wheels was also produced as model 33-0114.
