Especially large component dimensions often make it necessary to load the furnace from above, usually by crane. The usable space of the furnace must be prepared accordingly. For this purpose trestles are often used to pick up the component. We customize these trestles according to your batch.

Depending on the respective specification, our box furnaces can be used for hardening, as well as for tempering and annealing of components with an optional dimension. For large box furnaces there is the option to install a walkway above the box to allow easy and safe loading.
