High Temperature Protection for Double Girder Foundry Crane

When used in harsh environment, such as lifting hot liquid steel ladle in steel mill, the overhead crane has the risks of being damaged by molten splash, heat and flames, resulting in great losses in time and money. Therefore, the steel mill crane should take several heat safe measures to tackle severe working environments as well as protect the equipment itself.

  • The cabin room will apply heat insulation measure to ensure the safety of operators. The same goes with main beam.
  • To ensure a safe lifting operation, forged hook and steel core wire rope will be adopted.
  • The motor of class H insulation is adopted.
  • The crane wheels are forged or rolled.
  • Double brakes are applied to ensure a secure lifting.
  • The festoon cable system is constructed from high temperature materials to resist hot molten metal splash.
