HOWO 4x2 Road-Maintenance Sprinkler, 7 m³ Nominal Tank

The HOWO 4x2 road-maintenance sprinkler has a 7 m³ physical carbon-steel tank with a square-round form and anti-wave baffles. It is intended for local road cleaning and high-pressure flushing, with optional mist-cannon and special-cleaning equipment. The spray width exceeds 16 m. The tank size is the shell volume, not an approved road water load; the permissible fill amount is unverified and must be set from the final registration and axle ratings before use. A full 7 m³ water load must not be assumed.

The Sinotruk HOWO chassis has a 3,300 mm wheelbase and overall dimensions of 5,995 × 2,050 or 2,090 × 2,800 mm. The cab seats two or three people. Mass and axle figures for this configuration require confirmation. Weichai China VI diesel engine options include 96, 118 and 132 kW versions. The automatic transmission is paired with standard ABS.

Short overall length helps the driver position the truck on narrower local streets and around road-maintenance work. The carbon-steel tank and baffles support controlled water transport at the approved fill level. Optional warning lights, mist-cannon equipment and cleaning attachments let operators select a body layout for the actual maintenance task. Final water volume for travel should be set only after the truck's crew, equipment and approved mass have been checked together.
