Description
Tow high-output hot water washing capability directly to remote jobsites. The Simpson 4000 PSI 4.0 GPM Gas trailer package delivers self-contained mobile cleaning power. A 200-gallon onboard water tank feeds an industrial diesel-fired wash system. The massive gross trailer weight requires a half-ton pickup truck for transport.
A 3500-pound leaf-spring axle supports the 2-inch tubular steel chassis. The powertrain consists of a 408cc Vanguard engine coupled to a CAT triplex plunger pump. Schedule 80 steel pipe winds through the diesel burner chamber to resist intense thermal expansion. A rear-mounted manual hose reel holds heavy wire-braided pressure line. Powder-coated fenders protect the frame from road rocks.
Trailer System Feature Highlights
Road crews clean highway barriers and graffiti using remote fluid storage. The onboard tank system eliminates dependence on local fire hydrants or field water taps.
- Vanguard 408cc commercial engine delivers brute driving torque to the pump
- CAT triplex plunger pump supplies 4000 PSI for extreme industrial stripping
- Horizontal heating coil burns fuel oil to generate continuous 200°F water
- Integrated 200-gallon polyethylene tank guarantees steady fluid supply during remote washes
- Manual heavy-duty hose reel stores long hose lengths without kinking problems
- Steel trailer frame features DOT-approved LED lighting for highway towing safety
- Four quick-connect spray nozzles adjust spray fans for distinct wash tasks
Mobile Dynamometer Stress Data
Dynamometer pull testing records 3520 RPM under full 4000 PSI trigger lock. Flow meters measure continuous 4.02 GPM delivery at the nozzle tip. The burner elevates 60°F inlet water to 195°F within 90 seconds. Engine fuel consumption registers 0.95 GPH while the burner burns 1.60 GPH diesel. Operator ear noise levels register 89 dBA at 10 meters distance.
Operational Realities Job Demands
You hook the 2-inch ball coupler to your truck hitch for rapid dispatch. The baffled tank minimizes fluid sloshing during highway turns. Do not tow this trailer with small passenger SUVs or light crossover vehicles. The dynamic liquid weight overpowers light vehicle brakes and causes dangerous trailer sway.
- Grease trailer axle wheel bearings every 6 months of road travel
- Descale the steel heating coil with acid wash solution once a year
- Drain the water storage tank before winter highway transport to prevent freezing
