Zero Emission Site Dumpers eMDX


The first
Mecalac 6-ton
zero emission
Site Dumper


Site dumpers are complementary machines that can quickly change the dynamic of a jobsite. Compact and maneuverable, capable of operating in all ground conditions, they provide an efficient solution for moving materials on the jobsite.

The new Mecalac eMDX retains the fundamentals and heritage of the Mecalac 6MDX site dumpers in terms of productivity, safety and reliability, while incorporating Mecalac’s technologies and expertise in zero emissions solutions.

Switch to Autonomy

Seamless switch to electric

Requirements of urban worksites as well as the habits of operators have been taken into account to develop the Mecalac eMDX site dumper so that the machine autonomy and productivity are not impacted.

With a record battery capacity of 75 kW.h, the eMDX can operate intensively for a minimum of 8 hours non stop. Only 4 hours are required to charge the battery. The eMDX unrivalled 8-hour autonomy can be achieved thanks to the battery's power and heat management technologies. In your jobsite, this autonomy can translates into dozens of additional hours as site dumpers are mainly used on a periodic basis with frequent machine stops.

Switch to Performance

Largest 100% electric site dumper

Unlike “mini” electric site dumpers available on the market, Mecalac has focused its R&D investment to offer an emission-free solution for transporting materials on a scale never before achieved. The result is the Mecalac eMDX, the first 6-ton electric site dumper with uncompromising levels of autonomy, performance and safety.

The automatic transmission ensures that all the power of the electric motor is transmitted to the permanent four-wheel drive, for unrivalled power and efficiency on all terrains.

MDX-Series Cab: designed & tested to withstand impact

Switch to Safety

The safest cabbed dumper got even safer

In addition to the ROPS/FOPS certification, the cab of the eMDX has been tested by Mecalac to withstand impacts while loading the dumper skip. A series of front and side impact tests have been performed using different excavator swing speeds to simulate real impacts that could occur. The eMDX cab has proven to be highly resistant to potential impacts, reinforcing our leadership position in terms of safety.

Mecalac's design features ensure enhanced safety with easier machine access, excellent all-around visibility, and a higher level of operator protection. Adding to this, an advanced object detection radar identifies potential hazards in front of the machine, maximizing safety standards.
