Lightning Protection for Cranes, Luffing Cranes, Tower Cranes, Harbour Cranes

Lightning seeks the tallest and sharpest object around. This is why, lightning is the biggest natural threat to service providers that construct or operate metal structures such as Telecommunication Towers, Broadcast Towers, Antenna Towers, Cranes, Power Transmission Towers, Security Camera Masts, Military Telescopic Masts, and Sailboats.

 

Lightning Arrester/Rod is NOT the Solution. Why?

 

The answer is simple; lightning rods were not invented for metal structures.


“Catching a lightning strike” can be a good idea for ordinary buildings because the lightning rod, the down-conductor, and the grounding system are in bond with eachother and are all made of highly conductive material. The idea is to make the tip of the lightning rod the primary target, have the strike hit the rod, carry the lightning current through the down-conductor cable and let it reach the grounding system safely. Since the building is mostly made of non-conductive material such as concrete, lightning current can easily travel through the conductor cable without arcing into the building. 


 

However, this solution doesn’t work on a metal structure.

 

A metal tower is already a good conductive surface and the perfect path for the lightning current to flow down to the ground. Even with the best grounding system with the lowest resistance, lightning prefers to flow through large surfaces instead of a tiny conductor cable. Why? Well, simply because lightning current follows the easiest and fastest path to the ground, and flowing through a large surface is much easier than being prisoned within a tiny cable.


 

This results with damage to the equipment that is positioned on the towers. These can be antennas and radios on a telecom or broadcast tower, can be the electronics on a tower crane, power transmission lines held by the towers, outdoor cameras and wi-fi hub terminals on metal masts, etc..


 

To keep this equipment safe, Lightning must be kept AWAY from metal structures.

 

EvoDis® Lightning Prevention System for Cranes

 

EvoDis® System is a lightning prevention solution that keeps the strikes away from the cranes. EvoDis® is not a lightning arrester and does NOT attract strikes on itself or to the crane.


 

EvoDis® System collects the ground charges, divides them into smaller groups, and emits before letting them reach the opposite charge groups of the cloud. This process keeps the surrounding electrical field strength below the threshold level, blocks the formation of a lightning strike between the cloud and the crane and keeps the operator and all equipment on the crane safe,


 

EvoDis® Lightning Prevention System protects thousands of Cranes, Tower Cranes, Luffing Cranes, Mobile Cranes and other metal structures such as Telecom Towers, Radio&TV Broadcast Towers, Outdoor CCTV Cameras, HV Power Transmission Lines, Mobile Military Telescopic Masts, and Sailboats with 100% success for 18+ years.


 

If you own or operate any of the above structures, now you have a 100% solution to keep lightning strikes AWAY from them.
