Electric-powered Machines

Electric-powered Machines

Excitement was in the air at CONEXPO-CON/AGG 2020 with hybrid and battery-powered models highlighted.

The air was charged with excitement at CONEXPO-CON/AGG 2020 as multiple equipment suppliers chose to highlight hybrid and battery-powered concepts, prototypes and even a few production models. And even those not showcasing alternative-powered equipment had something to say about the latest technology advances available on their machines and intended to make the lives of equipment owners easier.

Following is a glimpse at some of the key highlights. You can find these and more at www.ForConstructionPros.com, as well as in upcoming issues.

Case Wows with Electric Backhoe-loader

Perhaps the biggest jaw dropper at CONEXPO-CON/AGG was “Project Zeus” – the 580 EV (Electric Vehicle) backhoe-loader unveiled on Day 1 of the show by Case Construction Equipment. The 580 EV offers power and performance equivalent to the company’s other backhoe-loaders while providing considerably lower daily operating costs and producing zero emissions.

 

The 580 EV is powered by a 480-volt, 90-kilowatt-hour lithium-ion battery pack that can be charged by any 220-volt/three-phase connection. While applications will vary, each charge will support most common eight-hour workdays. The battery separately powers the drivetrain and hydraulic motors, resulting in hydraulic breakout forces equal to diesel-powered machines and improved performance during simultaneous loader and drivetrain operation.

Though an electric backhoe-loader may seem unusual at first glance, Eric Zieser, director – global compact equipment product line, sees this machine type as an obvious choice for electric power. “The backhoe-loader is perfectly suited for electrification as the varied use cycles, from heavy to light work, provide an excellent opportunity to convert wasted diesel engine hours into zero consumption battery time, yet provide the operator with instantaneous torque response when needed,” he states. “At low idle a diesel engine has reduced torque and requires time for the engine to ramp up to meet the load demands. Electric motors, on the other hand, have instantaneous torque and peak torque available at every operating speed.” Read more here
