Liebherr: in the middle of Canada’s icy winter: LB 30 unplugged

Calgary has a clear goal: to reduce greenhouse gases. Part of the climate strategy is the use of emission-free technological innovations. With the first battery-powered unplugged model on Canadian soil, this strategy is also being consistently pursued in construction projects. During the construction of a new pedestrian overpass, contractor Graham and deep foundation subcontractor Ki International Ltd. put the LB 30 unplugged drilling rig purposely to the test with difficult drilling work and temperatures as low as minus 36 degrees.
