The new eArocs 400
Charged to change construction.
Equipped with long-life lithium iron phosphate batteries (LFP), the eArocs 400 is ready for use day and night. Thanks to its all-electric drive, it is ideal for low-noise and locally CO2‑neutral use in urban construction.1
Range
Enough for a full day.
With a range of up to 200 km2 as a concrete mixer and up to 240 km3 for the construction site tipper vehicle, the eArocs 400 easily handles an entire working day – with all its challenges. No matter what you use your eArocs 400 for, you can work during the day and recharge overnight at your leisure.
Robustness
Strong and reliable.
Ideally equipped for use in construction: With the usual robust components of the eArocs 400, you can move effortlessly over uneven terrain. Thanks to powerful electric drive and high ground clearance, you can effortlessly master the demands of your construction site.
Ready to go
Ready to go. 24/7.
The battery-electric drive of the eArocs 400 is significantly quieter than conventional diesel engines. This makes it ideal for noise-sensitive environments and zero-emission zones. With at least 50% less energy consumption compared to comparable diesel vehicles and a short charging time4, the eArocs 400 is extremely efficient and flexible in use.
Multimedia Cockpit Interactive 2
Digitally thought-out.
The touchscreen of Multimedia Cockpit Interactive 2 and the ergonomic switch panel offer superior operability even on uneven terrain. You can activate numerous functions with voice control – without taking your hands off the steering wheel. Applications relevant to you can be controlled via the favourites menu. And with integrated navigation for eTrucks, you will not only find the route that suits you, but also charging options along the route.

2 Rated capacity of a new battery, based on internally defined framework conditions. May vary depending on the application and environmental conditions.
3 The range was determined under specific conditions based on internal simulations using an 8x4 concrete mixer truck with a permissible gross vehicle weight of 32 t, operating the mixer drum for 8 hours at an ambient temperature of 20 °C. It may differ from the values established in accordance with Regulation (EU) 2017/2400 due to various factors such as topography, weather conditions, speed, preconditioning, auxiliary consumers, individual vehicle configuration and driving style.
4 The range was determined under specific conditions based on internal simulations with an 8x4 construction site tipper vehicle with a permissible gross vehicle weight of 32 t, operating the tipper body for 8 hours at an ambient temperature of 20°C. It may differ from the values established in accordance with Regulation (EU) 2017/2400 due to various factors such as topography, weather conditions, speed, preconditioning, auxiliary consumers, individual vehicle configuration and driving style.
5 The charging time is based on the framework conditions defined in ISO/SAE 12906 for heavy-duty commercial vehicles – with 400 kW charging capacity at a conventional DC rapid charging station with 500 A.
6 Assistance systems can only support drivers. The driver is always fully responsible for driving the vehicle safely.
