For loads of 10 tons the Lati 1ype NT.P., lorry and trailer is being widely employed. The lorry itself is constructed to carry b tons and to haul a further 5 tons on the trailer and includes a num ber of features of direct interest to overseas users. The engine is of 27.3 h.p. and forms a unit with the gearbox. There are 'b forward speeds and two differentials are carried in the gearbox, casing. A third is carried in a casing bolted to the rear of the chassis frame. The drive is transmitted through the longitudinal differential to the forward and rear differentials and thence by universally jointed driv ing shafts to the external toothed final reduction gears which are lockable froni the driving seat. On the rear of the chassis frame a spring towing hook is mounted.
