Improving the Safety of Transport by Crane Using Thermometer

In steel mills, iron slabs after manufactured are transported by magnetic cranes (lifting magnet). If the temperature of the iron slab is too high, the magnetic force of the crane gets weakened, so the temperature of the iron slab must be reduced to an appropriate temperature.

Therefore, it is necessary to go near to the crane to measure the surface temperature of the iron slab before transportation, but this is a time consuming and labor intensive process.

Issues

Voices of magnetic crane temperature check personnel

Need to maintain a safe distance from the measurement object for safety.
Time consuming due to manual checks
Repeatedly checking the exact measurement point from a far distance is difficult.
Temperature checks has to be done by visiting harsh environment.

HORIBA's Solution
