The secrets of the mysterious tanker truck chain
How does it work?
- Charge conduction: The chain, made of a conductive material, captures the electrical charges accumulated on the truck.
- Grounding: By coming into contact with the ground, it transfers these charges to the earth, thus discharging them.This mechanism acts like a “reverse lightning rod” , dissipating static charges before they become a threat.
A crucial safety device
The chain at the rear is just one of the many safety devices integrated into tanker trucks. Other measures include: - RTR grounding systems: A cable connects the truck to a fixed point during filling or emptying operations to prevent static electricity.
- Anti-electrostatic materials: Some components and tanks are made from materials that limit the generation of electrical charges.
