Our client uses Mersedes Actros for sand and broken stones transportation. Truck has following features:
- Extremely big roadtrain weight: more than 70tons which leads to extremely high diesel fuel consumption: 60-80L per 100km
- Automatic gearbox
- V-shape engine
- Full 6×4 wheel drive
Another client’s truck, Mersedes Axor has 4×2 wheel drive, so it works in comparatively easier conditions, in careers with smoother exit, but it also has extremely big full weight in 45-50 tons.
For dual-fuel conversion we used universal 24 V TRIOL convertion kit ( see special article ).
