Scrap metal can arrive at a steel mill by sea, rail or road. A crane is needed that can reach into the delivery vehicle and unload it. Speed is vital: the faster the vehicle is unloaded, the sooner it can depart.
We recommend unloading attachments that can be changed easily. Unloading is then continuous, with little sway and side movement, keeping each duty cycle short. Scrap is a difficult material, with no defined shape for a hook or tong to fit onto. A claw grab picks up anything it can work its teeth around. A magnet pulls complete pieces of metal onto its surface. We recommend a stable slewing trolley and unloading attachments that can be changed easily. The choice of attachment will be determined by what is being moved.
Sometimes more scrap is received than can be immediately processed. And it will often be mixed, needing to be sorted before smelting. You might have a large storage area, and your crane must be able to reach all parts of this area to access the right materials quickly. Delays are costly: a fast, reliable crane will deliver the right metal to the smelter on time.
A scrap-unloading crane for ships is built on the basic design of a ship-to-shore (STS) crane. Once onshore, a scrap crane is usually an overhead traveling crane for unloading a train or road vehicle, sorting the material, and loading the scrap bucket in readiness for the furnace. Both crane types can be adapted for your load types and site conditions, and equipped with a level of automation that fulfills your requirements.
