The Bauer GB 50 + DHG V Grab System is designed for excavating underground panels for applications such as diaphragm walls fro basements or slurry walls.

Please note the version sold through the Bauer shop is less functional than this version.


The packaging consists of an outer sleeve enclosing a set of trays.

There were no missing parts or defects on the review model other than a loose part which was easily refixed.

A very good instruction manual is included with the model and it has a parts list and written instructions in German and English together with annotated photos. 

There is no information about the real machine.


There are good quality metal crawler tracks with detailed pads but there are no working rollers on the track frames.  The drive sprockets and frames are detailed.

The cab is plastic but the interior is good with the controls modelled and small graphics on the cab door add to the look.  The metal walkway outside is textured.  Casting detailing on the body is very good with grilles and panel handles, and many very small and detailed graphics. 

There is a metal ladder, and the handrails around the top of the body are also metal.  There is a textured walkway on the roof and the winch assembly is a nice part whilst extra rope on the drums would have looked better than partially filled drums. Motors plug into the end of the winches.

At the back the counterweight is modelled of separate slabs.

The boom sections are metal.  There are metal pulleys for the hoses and ropes.  The large spoked hose reels are plastic and the colour match of these and the main boom rams is slightly off compared to the metal parts. At the boom foot there is a detailed winch.

The DHG V grab is an impressive large part which is mainly metal.   The frame is modelled in metal with the steering plates being plastic but they are detailed and have a good colour match to the metal parts.  Inside the frame the detailing is very good including the hydraulic ram that drives the grab. 

At the top the swivel motor is modelled.  The grab is metal with nicely highlighted teeth.


The tracks roll well and are mounted on extendible frames. 

The crane rotates smoothly.

The boom can be raised and lowered with the grab on and the rams are stiff enough to hold the pose.

Two of winches are operated by a key, and they have positive action brakes.  The winch at the boom foot has to be rotated by hand and it is fiddly.  The two hose reels can be rotated.

The grab can be held and raised and lowered although this means adjusting the three winches and two hose reels so it requires some coordination.

The grab opens and closes in a precise manner.

The grab frame rotates on its connection so that panels which are angled to the crane can be excavated.

A major plus point of the model is that it can be realistically stripped down to form transport loads, and in this regard it may be the best foundation machine model yet seen on Cranes Etc.

The crane counterweight is detachable as are the walkways, ladder and handrails, and the exhaust.  The winch assembly can be folded backwards to reduce the headroom.  The boom can be split in two.

The only downside of displaying the model as a transport load is that the hoses have to be cut and some work such as gluing would be required to reattach them.


This is a high quality model with plastic used appropriately.

The paint and graphics are excellent.


It is good value given the complexity and flexibility of the model.


This is perhaps the best Bauer foundation model yet.  It is detailed with very nice functionality, and the ability to split it down to make properly realistic transport loads is excellent.  However, note that the version of this model sold by the Bauer shop has many parts glued, so is not as flexible as this version.


This model first became available at Bauma 2019.
