Static grounding of unloading crane hoses
Thread Content
Friends, as shown in the picture, how should an electrostatic grounding wire be installed for the unloading hose? Is it necessary to lay an electrostatic grounding wire nearby in the ground to discharge static electricity during unloading, or can the electrostatic wire be directly connected to the crane pipe support during unloading to discharge static electricity? The flexible hose is 25 meters away from the tank, and the tank is grounded. Thank you.
Bury it nearby; jumpers need to be installed at all the rotating parts of the flexible hose
