GFS Corp recently announced the development of a new LNG Mine Haul Truck Conversion System for the Terex Unit Rig 4400 model haul truck.
Six Terex Unit Rig 4400 trucks will be converted at a mine in India, using GFS Corp’s newly developed EVO-MT® System. The first six trucks are scheduled to begin operating on LNG in early 2018 and the project is slated to expand in the near future to over 50 trucks. These are trucks already in use for some time, as the Unit Rig 4400 model is now part of Caterpillar and has been redeveloped into the Cat MT4400D AC.
The EVO-MT® System is an integrated system consisting of onboard fuel storage and vapourisation in addition to controls and safety systems that allow the truck to operate on a combination of LNG and diesel fuel, or NG+D® operation, as the company refers to it. The EVO-MT® 4400 system will provide 259 usable US gallons of onboard liquid natural gas storage, enough to complete a 12 hour shift.
GFS Corp currently offers retrofit systems for Caterpillar 777B, C and D, 785B, C and D, 793B, C and D trucks and 992G and K wheel loaders, as well as Komatsu 830DC, AC and 930E trucks. To date, the various EVO-MT® Systems have successfully logged well over 400,000 hours in actual mining operations in environments with temperatures ranging from -40 degrees F to above 100 degrees F.
“We are excited to add the Terex Unit Rig 4400 haul truck to our EVO-MT product lineup, said Jason Green, GFS Corp’s President and Chief Technology Officer. “This newly developed system expands on the growing list of mine equipment that can be converted to LNG using our NG+D® technology.”
