Protective glass for railways

Railway protective glass - Hammerglass

In cooperation with the Swedish Transport Authority, Hammerglass AB has manufactured a modern electrical canopy construction to cover overhead lines to replace the old sheet metal protective covers.The electrical shield is designed to withstand snow and wind loads, as well as wind loads from passing trains.The hard and smooth surface treatment of Hammerglass helps dirt and dust to be washed off the roof structure in most cases by rain.The surface treatment also provides 99.96% UV protection, meaning the material will not cloud, discolour or otherwise change in optical quality over time.

A 12mm LIFESAVER

Shields save lives.In the area of ​​high-voltage and overhead lines, there is always a risk of electrical accidents with serious personal injury.The roof construction made of unbreakable hammer glass corresponds to the electrical safety guidelines for electrical protective roof constructions for installation on bridges over railway tracks.The construction blends into the environment while providing a solid barrier against live wires.

• 12mm hammered glass mounted on a system of angled posts bolted to the side of the bridge edge beam
• Solid barrier against live conductors
• Waterproof and tamper proof
• Strength calculation considering snow and wind loads as well as wind loads from trains
• Meets the requirements for noise barriers set out in the CE standard EN-14388
• Execution class EXC2 or EXC3
• Can be mounted as a splash guard at street crossings

Construction and assembly

The canopy structure is 12mm thick hammered glass mounted on a system of angled posts bolted to the side of the bridge edge beam.When renovating bridges or in new construction projects, the angled post with base plate is mounted under the railing post.The roof construction has been fatigue-calculated by simulating the snow and wind loads as well as the wind load from passing trains and also meets the requirements for noise barriers specified in the CE standard EN-14388.The solution is waterproof and tamper proof and can be manufactured to execution class EXC2 or EXC3.We are able to take on complete jobs from the dismantling of existing protective structures to the installation of a new electrical protective roof in Hammerglass.Our designers provide ready-made drawings with fastening solutions in the form of dwg files.
