SMART POWERIn most mining operations trucks only half of the total working hours are used to haul material. During the other half the truck is empty. Large diesel engines are not efficient under partly loaded conditions. ETF developed a creative way to overcome this inefficiency. Instead of using one large engine, ETF incorporates four smaller capacity engines. One engine is in use during empty hauling, two or three engines are in use during loaded hauling and the fourth engine comes into operation when full power is required while hauling on grade. The engines start in rotation 1-2-3-4 and quickly achieving the required RPM by electronically synchronizing with the others that are running. The Electronic Control System is automatically governing the moment of start and stop of all the individual engines. The whole operation is fully automatic and cannot be influenced by the operator.
Another unique ETF feature is a redundancy package to backup systems like steering and braking power. If one engine should develop a problem, it will ‘automatically’ shut down with no involvement needed by the operator, the truck maintains fully operational, until a scheduled workshop diagnosis is arranged.
Power costs savings of up to 25 % can be realized
Power packs are equipped with an unique quick coupling system enabling fast swap in case of maintenance and repair. Complete exchange of individual power packs within 15 minutes!!
