Gaseous Fuel Systems Corp. (GFS) has announced that it has received an order to convert an entire fleet of Caterpillar 785 trucks to LNG fuel at an unnamed mine in the US.

The company claims that the trucks are expected to be in operation by late January 2017.

The new systems join GFS Corp’s product lineup that include NG+D® systems for the Caterpillar 777 and 793 as well as the Komatsu 830 and 930 haul trucks. Trucks with these systems have successfully accumulated over 400,000 hours of runtime to date, in mine service, substituting lower cost, cleaner burning LNG for a substantial portion of the diesel fuel that the truck would have normally used.

The President and CTO of GFS, Jason Green, said: “The 785 is a very common model of haul truck, used in mines in many parts of the world where LNG is readily available and diesel costs are relatively high […] We are excited to be able to add these new systems to our product offerings.”
