Perolo DCMT4. Earthing (grounding) device.
An grounding cable connects a tank trailer to earth in order to prevent load ignition. This is an important safety feature when loading or unloading flammable liquids such as petrol.
These are the specifications that can be required for such a device. Always ask specifically for specifications of a grounding device.
