A compact city crane.
The box.
The boom folds right down. The lock on the steering is excellent.

It poses well with the boom extended.
The AC40-1 is one of the very successful Demag 'City Class' cranes.  This crane has 3 axles.  For a picture of the real machine click here.


The model is securely packed within the usual polystyrene case and is contained within a box which has pictures and technical details. 

The review model arrived undamaged but was assembled incorrectly and a couple parts had to be reversed.

There are no instructions.


The base of the crane is a simple but good casting with painted lights.  The crane superstructure is similar with an orange beacon light provided on the roof.  Cab details are adequate.

The model lacks windscreen wipers and mirrors.

The boom has five sections and the winch is fixed on top of the lower boom section.  At the boom head the plastic pulleys are free-rolling.  Fixing holes for a folding fly jib are provided, but the jib is not.


All axles of the crane steer and the rear two axles are joined so that they steer together.  The steering axles are very well executed and look good when a hard lock is applied.  All the main crane functions operate so as usual the model can be posed in many ways.  Outriggers pull out and can be screwed down so the model is stable if the crane is posed working.  For transport there is a 'fender' piece which clips onto the lowered boom, and for use in confined spaces there is a mini boom extension (runner) which clips on.  When not in use the runner stows in a pocket at the rear of the crane.

The winch has no winding mechanism, but it is easily operated by finger rolling the winding drum itself, which has been ridged for this purpose.  Usefully, two hooks are provided, a single line metal hook and a three pulley block.  There is a loop for attaching whichever hook is strung in transport mode.  Strangely, on the review model, the loop was on the rear of the model but this was easily rectified by undoing a couple of screws and swapping two pieces.


The casting details are good as is the paint and graphics.  The outrigger beams are plastic as are the boom extension, fender, pulleys and toolbox.


The model is good value.


This is a pleasing model, and is well made.  It would have been even better if a folding jib had been provided and the outriggers in particular had been made of metal.


The model was introduced in 2000.  The initial version of this model was produced in Demag white prior to the takeover by Terex.  The later version was produced in Terex cream.  A number of versions have been available in crane company liveries.
The model in the tray.
The boom extension is kept in a pocket at the rear.
Set up for a simple lift.
The boom extension is good for those low headroom lifts.
