2. Electrification Of A Tiltrotator : Electrifying The Hydraulic Tilt Function
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : As new emission regulations in the EU set more stringent requirements on greenhouse gas (GHG) emissions, original equipment manufacturers (OEM) must find ways to align with the EUs sustainability goals. By transitioning to more electrically driven machinery, operators of off-highway vehicles can benefit from better fuel economy, lower greenhouse gas emissions and less air pollution. READ MORE

4. A bonded discrete element approach to simulate loading with hydraulic mining excavators
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. READ MORE
