The facility receives 20 trainloads of steel per week from Corus Steel’s mill in Llanwern, Wales, and offloads it into storage until it is loaded on to trucks for road transport.
The Street contract included the removal of three of the existing cranes and installation of five new cranes. Four of the new cranes are rated at 35t safe working load and one at 42t. Six coil grabs and one magnetic coil lift have been installed on the new and existing cranes. New crane rails of 750m (2,460 ft) have been erected with 712m of high-level fall safety lines.
The new cranes all include inverter control for smooth power take up and acceleration, while Street’s X-Y-Zero load stability system on all motions helps prevent load swing, improves safety and reduces loading cycles. Due to the high intensity of usage, all crane mechanisms are rated for the highest FEM duty and lifting usage rating, M8.
The 140,000 sq ft (12,880 sq m) Round Oak facility can hold up to 60,000t of steel. With the new cranes, it has an annual capacity of 1.25 million tonnes.
