3. 2. An Electro-Hydraulically Controlled Cylinder on a Loader Crane

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Johan Edén; Fabian Lagerstedt; [2018]
   Keywords : pump controlled cylinder crane asynchronos motor energy efficieny control;

   Abstract : With tighter emission regulations for road vehicles pushing the technology forward, fuel savings are indirectly affecting the designs and technical solutions of loader cranes. By decentralizing the hydraulic power through driving each actuator separately, the goal of a more efficient crane drive is strived for. READ MORE

4. 3. Arbetsresultat efter markberedning med en tvåhövdad hängande testbänk med inversfunktion

   University essay from SLU/School for Forest Management

   Author : Martin Andersson; [2018]
   Keywords : invers; högläggning; aggregat;

   Abstract : Today, inverting is performed mostly using crane-mounted devices. These devices must increase their productivity in order to become more cost-competitive. One way to increase productivity is to make a two-headed device that can prepare the soil using both inverting and mounding. READ MORE
