Protective glass for railways

Protective glass for railways - Hammerglass

In collaboration with the Swedish Transport Administration, Hammerglass AB has produced a modern electrical canopy structure 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 the wind load from passing trains. Hammerglass' hard and smooth surface treatment helps ensure that dirt and dust are washed off the roof structure by rain in most cases. The surface treatment also provides 99.96% UV protection, which means that the material will not cloud, discolor or undergo any other change in optical quality over time.

A 12 millimeter LIFESAVER

Protective shields save lives. In the area of ​​high-voltage and overhead lines, there is always a risk of electrical accidents with serious personal injuries. The roof structure made of shatter-proof hammer glass complies with the electrical safety guidelines for electrical protective roof structures for installation on bridges over railway tracks. The structure blends in with the surroundings and at the same time forms a solid barrier against live lines.

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

construction and assembly

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