  • Advance railings are used to provide the erector of a scaffolding with certain safety elements when climbing up to the top, newly created scaffolding level, which offer him a hold. After the safety railing has been erected, the leading railings are released again and used to secure a new section. Such devices are also called leading fuses.
  • the object of the present invention is to remedy such and other disadvantages of the prior art and in particular to specify a device of the type mentioned at the outset that enables the assembly of a leading railing from an existing scaffolding level in a simple manner for a scaffolding level to be created above it, which significantly reduces the assembly effort for providing the leading railing, which can be produced economically and which can be assembled and moved by just one fitter.
