Unique Electric Wheeled Excavator Concept from DEVELON

• DEVELON introduces the 14W-EREV electric wheeled excavator concept at Intermat 2024, showcasing zero emissions and advanced efficiency features.

• The 14W-EREV is designed for urban use, offering compact versatility, enhanced visibility, and increased stability and mobility for safety in challenging conditions.

• Features include a regenerating drive system (eDrive), advanced swing system (eSwing), and eWorking systems for optimal efficiency and performance.

• Equipped with an Around View Monitor (AVM) for 360° visibility, the excavator ensures safety by easily detecting obstacles in urban environments.

• The 14W-EREV boasts an independent electric pump motor for maximum hydraulic flow and a boom swing capability for working in tight spaces or inside buildings.

• Offers quick battery charging technology, with up to 80% charge in 1.5 hours, and an optional 55 kW diesel engine or an additional 120 kW battery pack for extended autonomy.

Being debuted at Intermat 2024, the 14W-EREV electric concept vehicle from DEVELON, formerly Doosan Construction Equipment, is the most advanced, state-of-the-art machine of its kind. This electric wheeled excavator is designed with a regenerating drive system (eDrive), advanced swing system (eSwing) and eWorking systems to ensure maximum efficiency with zero emissions.

The 14W-EREV is intended to excel in urban environments, offering a compact and very versatile design. The 14W-EREV combines this with enhanced visibility, increased stability and mobility to ensure increase safety on urban sites and in challenging conditions.

Built with a streamlined design, the 14W-EREV maximises peripheral vision over long distances for optimum safety and security. Offering the driver a full 360° of line of sight around the machine, the 14W-EREV can easily detect obstacles from any angle and in any urban environment. Equipped with an Around View Monitor (AVM), the 14W-EREV provides a full-screen projection of the machine’s journey and surroundings.

The 14W-EREV offers an independent electric pump motor, which helps to maximize hydraulic flow for attachments and provides a high flow for applications such as tiltrotators and articulated front pieces. In addition, the 14W-EREV offers a boom swing capability ideal for use in either tight spaces or buildings due to the working envelope being below 4 m.

Excellent Combination of Stability and Power

With its low centre of gravity, the 14W-EREV provides excellent stability both while working and while driving. For added convenience, a dozer/out-trigger option is also available to help the operator get the most out of the machine. While providing great stability and power, the 14W-EREV also offers impeccable build quality that ensures peace of mind when embarking on any project.

With its independent electric travel motor providing high traction effort and acceleration, the driver is able to take on more. Its four wheel steering is designed to minimize the turning radius and provide maximum control during road trips. And with round mode and crab mode available, making U-turns on the road is a simple process. During deceleration, the operator can enjoy a smooth ride while at the same time taking advantage of the energy regeneration process to increase the battery's life.

Innovative Solution for High Performance with Zero-Emissions

Improved battery charging technology allows the machine to be quickly charged up to 80% in 1.5 hours for the main battery. The battery pack has a capacity of 120 kWh, which allows 3 hours of driving and is therefore the ideal solution for zero emission areas.

Develon offers, as an option, the choice between a 55 kW diesel engine, for a hybrid solution, or a second additional 120 kW battery pack, which will add 3 hours of additional autonomy. The optional diesel engine helps users to deal with infrastructure issues on site, where there is no possibility of recharging.
