Lifting equipment with innovation

Today, however, the premium manufacturers’ eye-catching powder coating has another important characteristic in addition to good visibility and optimal corrosion protection. The coating is a heat indicator. It changes colour permanently under temperature influence and provides information about a potential reduction of the load-carrying capacity. With controlled, consistent coating and colouring, this colour change can be tested very accurately under laboratory conditions and recorded in a colour chart. The colour chart then serves as a simple aid for determining the maximum temperature reached.

The colour change is already relevant when temperatures of 100°C are exceeded. Permanent reduction of the load-carrying capacity in the lifting equipment can occur, decreasing slightly from 100°C and significantly above 200°C.

These reductions are usually determined under laboratory conditions and given as percentage reduction factors.
