The Crosby Group steel products, forged and cast, can be used in the general conditions of service up to temperatures of -40 ° F (-40 ° C).
In the case of temperatures from 0 ° F to -40 ° F (-18 ° C to -40 ° C) the correct implementation of the actions requires special attention in the following cases:

  1. The lifting should be done at a steady pace. Avoid overloading.
  2. The equipment with bearings should be checked and serviced more frequently and may require special lubrication.
  3. All lifting equipment should be checked before each lift.
  4. Remove notches, grooves or cracks by grinding (maximum removal of material equal to 5%).
  5. Do not use accessories that have been soldered or altered once they leave the factory.
  6. If deemed necessary by the user, the lifting equipment should be regularly inspected by an examination of the surface magnetic particle and liquid penetrant colored.

For actions at temperatures below -40 ° F (-40 ° C), you have to consider the “COLD TUFF” product.


With this line of accessories, The Crosby Group has given a significant contribution to the famous Antarctic expedition called “The Coldest Journey“, organized and led by the world’s greatest living explorer, Sir Ranulph Fiennes, which includes the complete crossing of Antarctica during the winter.

Not only the shipment aims to complete this ambitious goal by testing the human resistance to climatic conditions impossible, but aims to raise $ 10 million for “Seeing is Believing”, a global charity initiative to fight avoidable blindness in developing countries development.
