AK - Les Awirs 3-1

Transport through the trees

In Flémalle, near Liège, Electrabel is transforming an old mining site into a green zone. The slag heap may look green on the outside, it certainly isn’t inside. Eventually it must disappear altogether, with as little hindrance as possible to the surroundings. Therefore, Aertssen Cranes was commissioned to assemble a 1.7 km long conveyor belt, right through the Ardennes countryside.

In Flémalle, near Liège, Electrabel is transforming an old mining site into a green zone. The slag heap may look green on the outside, it certainly isn’t inside. Eventually it must disappear altogether, with as little hindrance as possible to the surroundings. Therefore, Aertssen Cranes was commissioned to assemble a 1.7 km long conveyor belt, right through the Ardennes countryside.

Between 1952 and 1972, at least 1.7 million tons of fly ash heaped up on the slag heap. This residual product was released during the combustion of coal in the old power station at Les Awirs. However, the stability of this slag heap is threatened, and so it must go.

Its destination being a series of cement factories throughout Belgium. But before it arrives there, it needs to be transported to the quay on the Meuse – without hindrance to neighbouring residents or nature. So the best solution is to create a closed 1.7 km long conveyor belt which is being installed by Aertssen Kranen. The conveyor belt had better be solidly constructed – just like everything else that Aertssen builds of course -, because in the coming 13 years, it will transport two thousand tons of ash a day. Our 80, 120, 140, 250, 300 and 500-ton cranes were employed for this challenging assembly work. Some components were lifted in tandem by our two largest cranes on site - AC 500s with a 36-metre movable lifting boom. Fast, meticulous and professional. So that from October 2016 on, the conveyor belt will be able to do its job continuously until 2029!
