This sharp Bauer BG 39 of Max Bögl from Neumarkt (DE) was used to drill piles for a new viaduct over a railway. This rig has a maximum total mass of 180 tonnes.
The functions of the drilling rig are powered by four hydraulic oil pumps, which are powered by a 433 kW-strong CAT C15 diesel engine. The diesel tank has a volume of 800 liter.
On top of the superstructure is the 38 tonne main winch installed. This winch must be removed for the transport over the road and has a total mass of 7.8 tonnes including 140 meter of hoist rope.
The undercarriage is 6.46 meters long and 5 meters wide. For the transport over the road can the width be reduced to 3.7 meters. The crawlers can be dismantled to and have a mass of 15.5 tonnes each.

The maximum length of the leader is 28.3 meters. Depending on the rotary drive is it possible to drill piles with a diameter up to 3.7 meters.
