Energy utilization is quite poor in hydraulic booms. Modern mobile machines load sensing hydraulics is used. Because hydraulic booms are multi degree-of-freedom mechanisms, it is very challenging task to improve energy utilization in hydraulic boom applications. Energy consumption is estimated in a selected work cycle by simulations. Different possible methods to regenerate energy in an example boom are presented. A method to cross utilize different DOFs is proposed. Comparison between load sensing and proposed method is done. Simulations show quite promising results.
