The scale model of the Sennebogen 5500 was the first mass-produced large crawler crane model and it appeared as a prototype at the BAUMA exhibition in 2001, and went on sale in 2002. 

This 5500G version is updated with some revisions to the 'Go for Green' revision of 2012.


The box sleeve is Sennebogen branded and contains two polystyrene trays which have a large number of individual pieces securely packed.  Surprisingly, the two extra counterweight pieces included with this version of the model were packed loose and unprotected meaning that some collectors may receive parts with paint chipped during shipping.

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

A detailed instruction sheet is provided, complete with pictures, and it is in German and English.  It is not revised for this version of the model.  It does not describe all aspects of the assembly such as which winch drums to use.  The winch drums should be used as follows (numbering the winch drums 1 to 4 from front to back):

- 1 is used for the hook when there is only a main boom or for the hook for the luffing jib if the crane is using two hooks;
- 2 is used for the hook on the main boom when the luffing jib is attached;
- 3 is a double drum and controls the luffing of the main boom using the pulleys on the A-frame (except the centre pulley);
- 4 controls the luffing jib - the rope goes under and around the single pulley on the body and then up and over the centre pulley on the A-frame and on up to the luffing gear pulleys.

Two drums have rope installed out of the box, and two spools of rope are supplied for the other two.  On the review model surprisingly there was not enough rope pre-installed on the jib luffing drum to facilitate a full range of movement.


Each crawler track comes as a separate unit.  The tracks themselves are plastic made up of a large number of interlocking sections.  They look very good although they are occasionally a little stiff so do not always lie naturally.  The only other moving parts on the track frame are the main sprockets.

The main piece of the model crane consists of the cross frame that links the two track frames, the crane body and first section of boom.  The cross frame snaps into position into openings in the track frames and this provides a robust fixing mechanism.   The self-raising jacks are simple screw threads which are crude by modern standards.

The cab design is new on this version.  It is metal with grab rails and an unsilvered mirror, and good interior details such as foot pedals.  The main body is relatively uncomplicated except at the rear where the counterweight attachment mechanism is modelled well, and is complete with cylinders and lifting chains although the plastic cylinder pistons would look better if they were silver. 

Four separate winches are available to be used, and there are holes in the body to allow entry of the operating keys.  The pulleys on the body and A-frame are metal rather and they roll freely. 

The counterweight plate attaches with a pin and pairs of six weights sit on top, including the new larger plates which are part of the 5500G.  For some reason the graphic chevrons on the new plates are slightly off colour.  Each counterweight piece is cast with useable lifting lugs.  Not included on the model are the ballast plates used on the real machine which span between the track frames front and rear. 

The first section of the main boom is permanently fixed to the crane body together with spring-loaded bars to prevent the boom being over luffed into a vertical position.  All sections of the boom are made extremely well and look fine.  They join together using the plastic pin system which is very effective. 

The main boom head has snap-in large plastic pulleys which are satisfactory but perhaps not the best in their ability to free-roll, and they also appear to have an over-large separation between the sheaves. 

With the luffing jib attached an excellent cable arrangement is provided to prevent the jib over-luffing but on the review model the two upper ropes were not the same length.

The pendant bars used to support the boom and jib are all modelled in tough plastic.  They are pinned together so they remain straight under tension.

There is no dolly wheel at the end of the fly jib and this would have been a worthwhile addition. 

The hook is only a single pulley affair but looks smart with chevron stripes.  It is metal and looks fine on the fly jib but the main boom really calls for something larger.  The pulley inside the hook is plastic and would not turn on the review model.


The tracks roll well by hand and work very well when the crane is built up.  The jacks lower by unscrewing.

The cab is mounted on a tilting and hinge arrangement so that it can be moved inward to reduce the crane width during transport and can be rotated upward to a steep angle to aid the driver during lifts at height.  The mechanism was loose when the cab is horizontal so it drooped down a bit.  It would have been nice if the walkway outside the cab had been hinged so that it can be stowed during transportation.  

The four winches are operated by keys which are metal.  They can also be removed when not used so they do not distract from the look although the holes remain.  To insert the key in the jib luffing winch requires pushing out the internal axle so care is needed not to push it too far.

The luffing gears work well due to the free-rolling metal pulleys.  The hook function is poor because of the plastic pulleys used.

The main strength of this model is the large variety of ways the model can be displayed.  It can be broken down for transport so looks very good on appropriate haulage vehicles.  It can also be displayed in various stages of assembly. 

The crane can be rigged a number of ways.  It can have just a main boom of various lengths, including very short if you want it.  It can have a luffing jib of different lengths giving an overall model height of about 1.2m.  Another option arises because the reducer section at the top of the main boom can have jib sections directly attached to create a long boom with reducing section towards the top.  Under this configuration the model stands around 1.1m high.

In terms of stability the model is fine and is improved by the addition of the two new counterweights.


The casting of the boom sections is very good and overall the model has a quality feel. 

The Sennebogen green paint scheme looks really good and the few graphics are sharp.


The price of the model has increased significantly with this revision and this is not accounted for by the limited improvements which have been made.


This model has been in production for around 17 years since its first release.  This version has a few incremental improvements since the upgrade in 2011, and a significant price increase. It remains a good looking, flexible model.

However, it is disappointing that Conrad did not do more to modernise and improve the model given that many changes could have been low cost.


The Sennebogen 5500 crawler crane was originally introduced in 2002 in yellow and grey livery and was reviewed here

In 2011 an updated version was introduced.

This updated version, the 5500G, was introduced for Bauma 2019.
The contents.
Decent looking load.  The Arocs truck is in Sennebogen colours.
Counterweight and lattice sections.
Overall look is very good.
Textured walkway surfaces.
Small hook for a big boom. It is better to only fit two pulleys on the boom head so they roll properly.
Plastic sign boards on the jib.
Overall profile is very good.
