The fully electric transporter “Ec70”, presented by Caron in Bologna, aims to assess the applicability of zero-emission propulsion in specific operational contexts. This environmentally virtuous approach, however, does not come at the expense of the machine’s operational capabilities.
Exploring new propulsion solutions to address energy transition policies in a way best suited to each specific operational need—this is the design philosophy behind the “Ec70” transporter. Premiered at Eima 2024 by Caron, this fully electric prototype was developed by the Vicenza-based company to evaluate the feasibility of zero-emission propulsion, particularly in scenarios where quiet and non-polluting vehicles are advantageous for securing public maintenance service contracts.
Applications include municipal tasks in low-emission zones, green space management in parks and urban gardens, and maintenance of beaches and stadiums. The “Ec70” meets these mission profiles without compromising performance compared to conventional internal combustion engine models. This is achieved through a powertrain built around a 50-kilowatt synchronous permanent magnet electric motor (approximately 68 horsepower) and 300 Newton-meters of peak torque.
Performance-Driven Design with Advanced Battery and Powertrain Systems
Powered by a 35-kilowatt-hour lithium-ion battery pack operating at 350 volts, the “Ec70” supports charging modes up to 22 kilowatts. The traction motor can also be complemented by a secondary electric unit dedicated to operating the power take-off (PTO). This setup enables the “Ec70” to utilize an increasing array of electrically controlled equipment, facilitating entirely eco-friendly work sites.
This environmental commitment does not compromise the operational standards expected from Caron transporters. A dual-speed transmission—one gear for precise tasks and another for road transfers — allows the machine to handle gradients of up to 100% even at full load, with a total weight capacity of up to 5,000 kilograms.
Innovative Regenerative Braking
Enhancing the management of the electric powertrain is an adjustable regenerative braking system, which incorporates a retarder function. This allows the machine to slow down simply by releasing the accelerator, with the braking effect provided by the resistance of the electric motor, particularly useful during downhill operations.
In summary, the “Ec70” represents a forward-thinking step in environmentally conscious engineering, delivering zero-emission solutions without sacrificing the operational capabilities Caron machines are renowned for.
