Looks very good in the Sennebogen colour scheme.
Removable panel to access the winches.

Overall profile is very good.
At work.

The Sennebogen 6140e is a heavy duty crawler crane designed for repetitive stressful loadings.  It has a 140 tonne capacity and a maximum main boom length of 63.5m.

This model comes with a dragline attachment.  The real machine is rated for a bucket size of 5.4m.


It comes in a very large branded box because the model is fully assembled and reeved.  The model is secured to the bottom tray with a string tie. 

The review model had no missing parts.  Some of the metal handrails were not straight.

A few technical details of the real machine are included on the box and a simple pictorial instruction sheet with photos describes the main features of the model.


The metal tracks are shaped with nice detailing.  They are mounted on decent track frames with no moving rollers but there are small graphics and steps.

The cab is plastic with a mirror, grab rails and a windscreen wiper.  Metal walkways and handrails surround the body.  TIt has a very good paint finish with small graphics and panel handles that look realistic.  On top there are textured surfaces and the handrails are metal.

At the rear the counterweights are solid blocks detailed with sharp graphics applied.  The chains are a little too bright in terms of their silvered finish and the pulleys for the boom luffing gear are separate brass pieces although they appear jammed in. 

The boom is metal with the mesh walkways formed by graphics printed on clear plastic.  The boom looks good but it is not jointed in the same sections as the real crane so it cannot be taken apart realistically.  Also the boom pendants are pliable plastic and they are fixed in length.

At the boom head the  brass pulleys would have looked better painted to match the real crane.

The dragline bucket seems over large and the draining perforations are also on the big side.  It is all metal but the front chains are two short to be realistic.


The tracks roll well by hand and the idlers on the frames are spring loaded to maintain tension.  The track frames are also retractable, so they could be set up in a narrow transport configuration.

The crane rotates well.

To gain access to the winches the whole of one side panel is removable.  Inside the panel there are a couple of large keys and these can be used to operate any of the three working winches.

The boom luffing winch can be used to adjust the boom angle although the rope does not move freely and some manual intervention is required.

There is no ability to reconfigure the boom as it is permanently riveted in the delivered configuration.  Similarly the counterweight is fixed in place and not made of individually separable parts although some pieces can be unscrewed.  However the counterweight lift cylinders can be raised and lowered a little.

The dragline bucket can be operated but it cannot be posed being emptied because of the short front chains. 


This is a robust model with a good finish, with just some of the handrails needing straightening out of the box. 

The paintwork and graphics are very good.


The model is reasonably priced overall.


Out of the box this is a very good looking model.  However, it could have been a great model if it had respected the real crane more, and if it could be split down like the real crane.


The model was released at the Bauma exhibition in 2019.  Versions were also made with a diaphragm walling attachment and a grab.

Model is fully assembled in the box.  Some handrails were not quite straight.
