Mobile drill rig uses electric drive for fume-free operation
Redevelopment of city centre locations can require drilling of deep bore holes to check the suitability of the soil and bed rock for supporting new buildings. If a site requires a comprehensive geological survey it may be necessary to drill inside existing buildings. However, most drills are diesel driven, meaning the exhaust fumes have to be extracted to the outside, a task that is difficult, time consuming, expensive and often not entirely successful. A new type of drilling rig, developed with the help of electric motor company Exico, can be used indoors without the risk of filling the building with diesel exhaust fumes.
