HOWO 371 / 375 / 380 / 400HP 4×2 Tractor Truck Available
HOWO 371 / 375 / 380 / 400HP 4×2 tractor truck is a heavy-duty prime mover designed for highway logistics, container transportation, port operations and medium-to-long-distance semi-trailer transport. The 4×2 axle configuration provides a lower curb weight, reduced fuel consumption, smaller turning radius and improved payload efficiency for standard road transportation. The truck can be equipped with SINOTRUK or Weichai diesel engines, HW-series manual transmission, heavy-duty rear drive axle, reinforced chassis frame and HW76 or HW79 sleeper cab. It is suitable for towing skeletal container trailers, flatbed trailers, sidewall trailers, fence trailers, tanker trailers and other standard semi-trailers. The HOWO-7 platform supports 4×2 tractor configurations, WD615 / D10 and WP10 / WP12 power systems, approximately 266–430PS power coverage and Euro II–Euro V emission configurations. Engine power, emission standard, cab type, fifth wheel, axle ratio, tires, fuel tank, driving side, color and accessories can be customized.
