E-quipment spotlight: Komatsu PC365-11 hybrid excavator

Because of a intelligent, absolutely electrical swing system and “increase up” energy help options, the massive PC365-11 hybrid excavator from Komatsu guarantees higher efficiency and critical gasoline financial savings in comparison with standard diesel machines.

Komatsu says its PC365-11 hybrid excavator makes use of a “boom-up” energy help characteristic that captures and shops kinetic vitality throughout completely different operation cycles, then faucets into that energy to offer an additional vitality increase when wanted. The result’s 15% extra productiveness and a 20% enchancment in gasoline effectivity when in comparison with non-hybrid excavators in ~40 ton class.

“The PC365LC-11 was engineered for excellence in multifunction functions by leveraging its revolutionary electrical powertrain system to spice up job website productiveness whereas lowering gasoline consumption,” says Matthew MoenKomatsu’s product supervisor. “To focus on these efficiency enhancements, we’re emphasizing the idea of ‘multifunction plus’ because the defining characteristic of this machine.”

The way it works

Komatsu’s hybrid system replaces the traditional hydraulic swing perform with a totally electrical swing motor that pulls energy from an ultracapacitor (versus a battery) vitality storage unit. As excavator slows or stops swinging, one thing like a regenerative braking system captures the kinetic vitality that might usually be misplaced as warmth and shops it within the capacitor. As soon as there, the saved vitality might be rapidly launched to energy the swing motor or help the engine, delivering as much as an additional 70 hp when wanted to help heavy lifting or digging cycles.

And, due to Komatsu’s proprietary software program, all of this vitality seize and reuse occurs automagically throughout regular work, with out the necessity for exterior charging. The gasoline financial savings occur as a result of eradicating the hydraulic load from the ICE engine permits it to run at an ultra-low idle, whereas the productiveness comes from the higher energy and general pace of the electrical operations vs. standard hydraulics.

Electrek’s Take

Belief me after I inform you that Komatsu didn’t get up at some point and resolve to construct a capacitor-based hybrid crane. One in every of their prospects had the thought and got here to them, promising orders. That’s what Komatsu does – from undersea distant management dozers to lunar mining rigs (above), in the event you carry Komatsu an order, they may completely discover a method to fill it.

As for PC365-11 hybrid excavator, it’s full of intelligent tech, general – providing vital gasoline, emissions, and TCO reductions with out dramatically altering the operational logistics of an current fleet’s operations. That’s all of the gross sales pitch it wants.
