Evaluation of an electro-hydraulic system of a working machine is carried out by a Matlab Simulink model. Modelling of the total forklift system is presented. Analysis and verification of the Simulink model with practical results are also performed for an axial piston hydraulic machine drive. Practical results are presented to demonstrate the cycle energy efficiency of the proposed electro-hydraulic forklift arrangement with potential energy recovery feature.
