Working under extreme conditions, it is important that powertrain assemblies on drilling systems perform with ultimate reliability. This is especially true of the drawworks, which reels the drilling line in and out during operation. A leading global manufacturer of drilling systems contacted Stromag to provide a bespoke IBV Eddy Current brake to meet its demanding drawworks specification.
