The Bauer BG 28 H Drilling Rig is a flexible machine used for a variety of foundation engineering tasks.  It is a Premium Line machine in the Bauer range.


The model comes in a nice quality Bauer-branded box with the model packed within black foam rubber. 

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

There is no information about the real machine.  A comprehensive instruction sheet describes the assembly.


The undercarriage has metal tracks mounted on frames which have no working rollers.  Plastic steps are fixed to the track frames.

The cab has metal grab rails and a plastic roof protection screen.  There is an unsilvered plastic mirror, and a windscreen wiper.  The walkway outside the cab is metal with a textured surface.

A metal ladder is mounted on the side of the body, and the graphics and paintwork are to a high standard.  At the rear the counterweight is in separate parts.  On the other side of the body the grilles look very good with painted openings.  On the roof there are textured surfaces and the exhaust pipe is metal.  The handrails are plastic and they look good.

Soft hydraulic hoses run from the front of the machine to the rotary drive.  The mast support structure is robustly modelled.  The hydraulic ram jackets are plastic and the colour match is slightly off compared to the metal parts.

The mast is modelled well with very good detailing.  The winches look realistic and metal sheaves are used throughout.  The auxiliary line has a small metal hook.

The kelly bar is metal with a plastic cap and the drilling bucket is metal also.  The rotary drive is excellent including springs to represent those on the real machine.  Also metal is the casing driver.


The tracks roll well on a rough surface and they are mounted on extendible track frames.

The model can be posed with an accurate transport width.  The steps on the track frames can be removed, the cab grab rail removed and the access platform can be slid under the cab.  The mirror can fold in towards the cab and the light bar at the top of the cab can be slid to a transport position.

The transport height can also be represented by folding the handrails and removing the exhaust pipe.

The ends of the mast can be folded to reduced the transport length.

The transport weight can be removed by removing the counterweight.

The top of the kelly bar unclips allowing it to be withdrawn from the rotary drive meaning realistic transport loads are possible.  However, the drilling bucket is not removable from the kelly bar.

The body rotates smoothly and without any rocking.

The mast is movable and can be posed in transport mode or erected.  The hydraulic rams are stiff and will hold any pose.

Three winches can be operated using supplied keys.  One controls the movement of the sledge up and down the mast, and the model is supplied reeved for this.  A second winch controls the raising and lowering of the kelly bar, and a third controls the auxiliary hoist.

The kelly bar and drilling bucket can be rotated, and the bucket flap opens.


This is solid and heavy model with a high metal content.

The paintwork and graphics are high quality.


The model is reasonable value.


Conrad has made an excellent model of the BG 28 H for Bauer.  It is highly functional and represents the real machine very well.


The model first appeared in January 2022.
