Project description

During the construction of the Grand Paris Express Metro Line (the largest urban construction project in Europe), 45 million tonnes of earth and rock has to be removed from the tunnels that are constructed. The material is partially transported to gypsum quarries in the Paris region. Groupe E.C.T. is moving the material to the old underground workings of, still operating, gypsum quarries.

Dumping safely and sustainably

In order to be able to dump the material in a safe and sustainable way, Groupe E.C.T. is using pushers that can dump the material closer to the hanging wall of the old workings.

The trucks are optimally designed for this project. The trucks are only 3.50 meters high. This allows trucks to stop very close to tunnel walls in case of emergencies so that emergency vehicles can pass. As it is important to achieve low exhaust emissions, especially underground, the trucks have a Euro 6 engine.

To meet French mining regulations and CE regulations, the trucks are equipped with rollover protection structure (ROPS) and falling object protective structure (FOPS). The pusher size is 28m3 (struck) allowing for a payload of 50 tonnes.

An employee of BAS Mining Trucks has been on site to train the drivers to drive safely and sustainably with these 50-tonnes payload trucks. Repair and maintenance will be carried out by ECT themselves in cooperation with Volvo Trucks France and BAS Mining Trucks.
