Fully electric wheel loader prototype showcased
Komatsu used the 2022 Bauma event to showcase a prototype of its first fully electric compact wheel loader. Recently designed and built together with Moog, this new connected and automation-ready construction machine is battery-powered and zero-emissions and is now ready for joint testing.
Moog’s Intelligent electric system includes an electric traction motor, lift, tilt and steering electric cylinders, power electronics, system control computer, battery, and battery management system. The integrated control system connects and coordinates the actions across the machine, while the all-electric actuators and motors provide the force to the machine’s traction and loading system. The integrated nature of the system enables industry-leading system efficiency and controllability.
Ambitious goals for carbon neutrality
“To achieve our CO2 emission reduction targets from products in use of 50% by 2030 from 2010 levels, to achieve carbon neutrality by the end of 2050, we are looking for promising technologies from suppliers to accelerate our electric machine development,” said Seiichi Fuchita, chief technology officer (CTO) and president of Development Division at Komatsu. “The machine built together with Moog combines the strengths of both companies and was finalised within a short period of time and we expect the joint testing will show the advantages of a full electric machine and will proof collaboration is beneficial for both sides.”
Both companies will jointly test the fully electric loader to prove that it can achieve a new level of efficiency, operating time, and comfort. The joint test will show that the machine’s operating cycle is extended, and, with innovative assist functions, that it provides a “fatigue-proof” and comfortable environment for the operator to manage the machine and his day.
An automation-ready electric loader solution
The prototype’s intelligent machine electrification system is designed to be connected and automation-ready. The system has the sensing and control capabilities needed for automation while the integrated software framework comes with built-in tools to coordinate multiple axes of motion and precisely control torque, velocity, position, and force.
