Presentation

Multi-criteria evaluation of electrification concepts for compact machines.

When developing a new zero-emission machine offer, multiple solutions are possible. Poclain's electromobility team, with its market experience and expertise in the field of power transmission for mobile equipment, offers you a multi-criteria assessment of the solutions implemented on its development platforms. During the conference, two electro-hydraulic solutions using different architectures will be detailed: one using a single electric motor for the propel function and the auxiliary functions, the other using two electric motors, the first one for the propel with a close loop fix displacement pump, the second one for auxiliary functions with open loop pumps. Both architectures will be detailed and evaluated.
