For firefighting at Netto high-bay warehouse, we have a unique mobile cart equipped with power and water to supply the crane in case of fire.
The principle is described here:
At the entrance to the warehouse fire-fighters connect power and water cables to the cart.
The cart is transported on rails to the crane while power cables are rolled out.
Power and water from the cart is connected to the crane.
The crew extinguish the fire from the warehouse crane.
