Success Story: NEO20 Lifting Hook in Foundry
20 January, 2020
As within a majority of foundries, the melting furnace is “charged” with metal and heated above the metal’s melting point. Once the molten metal has reached a specific pouring temperature it is tapped from the furnace through a spout into a pouring ladle.
In this case, the ladle’s oversized lifting point was almost 100mm in diameter, which represents a loading problem with traditional lifting hooks, and especially a safety and security headache for operators and technicians as any hook would need to be manually engaged (and released) from the lifting point.
With the NEO20 lifting hook‘s design and geometry, this was not the case and the fail-safe design hook was able to remotely engage the lifting point via remote control, avoiding the need of any person to be dangerously close to the ladle and/or melting furnace.
Another important issue at hand during the production process was the high temperatures and radiated heat. The NEO20, with its high-strength steel body, and all of its components, like the high-capacity battery had to withstand direct temperatures of up to 60ºC/140ºF during the “tapping” process.
The NEO20 lifting hook was equipped with a load cell. This load cell, in combination with the eMAX remote control, transforms the NEO20 into a precise weighing scale that informed of the weight that was being lifted during the whole process.
Once the ladle pours the molten metal into the mold cavity, the remaining liquid is emptied and the ladle is returned. Once again, the ladle is released remotely, via remote control, keeping operators at a safe distance.
