After a few months of installing the Earth-Rite MGV system on one of the company’s many industrial vacuum loaders, I received a call from an operator of the truck stating that the system would not build vacuum. I informed the operator that the reason the truck would not operate and build a vacuum was due to inadequate ground and that we have our MGV system interlocked so that if there is not an adequate ground, the vacuum system will stop operating.
I requested that the operator move the truck and find another grounding point, as the current grounding point might have been compromised in some way. The operator attached the MGV to a different ground point and reported back that the system was now working correctly. We were both happy to have resolved the issue so work could be carried out safely.
The operator notified the plant safety of the bad grounding point and we were commended by the customer we were working with for bringing this to their attention and for having a system in place that would not allow work to continue in a potentially unsafe area.
We have since installed many Newson Gale Earth-Rite MGV Systems on our equipment and have now made the system a standard on all vacuum loading equipment.
Thanks, Newson Gale.
