Coal Terminal

rail gauge to be used while also maximising the usable width of the stockyard. Richard Von Moltke, Lead Electrical and Instrumentation Engineer for Sandvik Mining, explains that the new substation is designed to optimise the network with built-in flexibility to isolate production areas. This makes recon- figuration possible as the old system could not

a high level of customisation to ensure the machines meet operational specifications. Where possible they will also need to interface directly with current infrastructure in order to avoid costly and time consuming rebuilds. With the shiploaders’ design capacities at a maximum 11 000 tons per hour and the stacker/ reclaimers able to process a maximum 6 000 tons per hour for stacking and reclaiming, the behemoth-sized machines are an ideal fit for the project requirements. All-around solution The Sandvik PL300 shiploader is a rail-borne, gantry-mounted, telescopic-boom shiploader with a steep luffing function that is designed to cover all hatches on vessels ranging from 40 000 DWT Handymax up to 175 000 DWT Capesize. During berthing operations of the ves- sels, the shiploader boom can be simply raised out of the way to reduce any risk of collision. The Sandvik PD200 stacker/reclaimer pro- vides efficient use of available space as a result of its innovative design. It is a rocker-type, heavy-duty machine that minimises the migra- tion of the centre of gravity in operation to allow very high capacities and an economical
