Traverses for handling of loads in nuclear facilities
Traverses or lifting beams are mechanical support systems used for stabilisation, fastening or connection. They are used as load bearing equipment when loads are attached to a crane. Traverses usually have a manual or automatic coupling system to the loads to be lifted. If necessary, emergency operating systems are also implemented.
Traverses are used in the reactor building, e.g. for handling the reactor lid, reactor internals (upper and lower core plate) or for handling of various waste containers.
Traverse components
The combined lifting traverse developed by Siempelkamp NIS lifts either the entire reactor internals or individual core plates, in each case without any alternations, which in turn saves time and costs to a considerable extent during outage inspections.
The combined lifting traverse is operated via a control panel, where all system statuses can be detected via signals.
Depending on the requirements, the combined lifting traverse can also be designed in a modular manner to allow its use in different power plants or units.
