Protective glass for railways

Protective glass for railways - Hammerglass

In collaboration with the Swedish Transport Authority, Hammerglass AB has developed a modern electric protective roof structure to cover overhead lines as a replacement for the old metal protective covers. The electric shield is designed to withstand snow and wind loads as well as the wind load from passing trains. The hard and smooth surface treatment of Hammerglass helps ensure that dirt and dust are washed away from the roof structure by rain in most cases. The surface treatment also provides 99.96 percent UV protection, meaning that the material will not become cloudy, discolor, or undergo any other change in optical quality over time.

A 12 millimeter BIG SAVER

Protective shields save lives.In the area of high voltage and overhead lines, there is always the risk of electrical accidents resulting in serious personal injuries. The roof structure made of shatterproof hammer glass complies with the electrical safety regulations for electrical protective roof structures to be installed on bridges over railway tracks. The construction integrates into the environment while simultaneously forming a solid barrier against live wires.

• 12-mm hammer glass, mounted on a system of angled posts that are 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 road intersections

Construction and assembly

The protective roof structure consists of 12 mm thick hammer glass, which is mounted on a system of angled posts that are bolted to the side of the bridge edge beam. During bridge renovation or new construction projects, the angled post with base plate is mounted under the railing post.The roof structure has been fatigue-calculated by simulating snow and wind loads, as well as wind loads from passing trains, and furthermore 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 capable of taking on complete projects from the dismantling of existing protective structures to the installation of a new electrical protective roof in Hammerglass. Our designers provide finished drawings with fastening solutions in the form of dwg files.
