BRIEF

The DONGFENG VR 12m³ Street Sweeper Truck is a purpose‑built cleaning vehicle that automates street sweeping and waste collection. It uses a central four‑brush system that sweeps debris from both sides toward the middle, while a powerful rear suction nozzle vacuums everything into a stainless steel hopper. When the hopper is full, the hydraulic lifting system raises it and opens the rear door for quick, clean dumping.

The truck is built for continuous heavy‑duty operation. Key components include Sanyo motors, a secondary engine for extended runtime, Schneider controls, and a complete Winsboro hydraulic system (valves, cylinders, and pump). An optional front/rear water spray function turns the same vehicle into both a sweeper and a sprinkler truck, making it suitable for factory campuses, residential areas, and municipal fleets.

In short, this street sweeper truck replaces manual street cleaning with a safe, efficient, and versatile machine. It reduces labor risk, lowers operating costs, and delivers cleaner roads with less water and fewer repeated passes.

FEATURES

1. Central Four‑Brush Arrangement

Four disc brushes sweep inward toward the center line of the truck instead of pushing debris sideways. The rear suction nozzle then collects everything in one pass, eliminating repeated runs over the same road section.

2. One‑Button Brush Engagement

The driver lowers the brushes and starts sweeping with a single switch. No manual adjustments or external work. The operator stays safely inside the cab, away from traffic.

3. Hydraulic Dumping System

When the hopper is full, the driver activates the hydraulic lift. The hopper raises and the rear door opens hydraulically, allowing waste to slide out cleanly. No shoveling, no climbing, no wasted time.

4. Stainless Steel Hopper

The entire hopper is made of stainless steel. It will not rust, even when collecting wet waste or working in humid coastal environments. This extends the body life and keeps the truck looking professional for years.

5. High‑Pressure Water Spray (Integrated)

A central wide spray bar plus left/right high‑pressure side spray bars deliver water precisely ahead of the brushes to loosen dirt and control dust. The side bars are arranged in a V shape, and the suction head has built‑in nozzles that push all wastewater and debris toward the suction inlet. After the truck passes, the road is clean and dry—no muddy streaks or standing water.

6. Independent Side Control

Left and right brushes and spray bars can be operated separately. When sweeping along a curb, the driver activates only the curb‑side brush, saving water and reducing wear on the opposite side. This also helps the truck handle partially obstructed roads more efficiently.

7. Automatic Obstacle Protection on Side Spray Bars

Each side spray bar is mounted on a spring‑loaded pivot. If the bar hits a manhole cover, a high curb, or any fixed obstacle, it swings back automatically and then returns to working position once clear. This prevents expensive breakage and keeps the truck running without constant manual repairs.

8. Hydraulic Floating Wide Spray Bar

The central wide spray bar is not rigidly fixed. It floats hydraulically, following the contour of the road surface. This reduces wear on the rubber support rollers and maintains a consistent spray height, improving dust suppression and water efficiency.

9. PLC Intelligent Control System

All sweeping, spraying, hopper lifting, and door opening functions are managed by a programmable logic controller (PLC). The driver controls everything from a simple panel inside the cab. No need to step outside, even during dumping—a real safety advantage on busy streets.

10. Separate Clean Water and Wastewater Tanks

The clean water tank and the hopper (which also holds wastewater) are separate units. This layout maximizes usable space on the truck. For long shifts, the operator can partially drain wastewater on‑site (where regulations allow) and top up clean water without returning to the depot, significantly extending continuous operation time.

11. Optional Front/Rear Sprinkler Function – Two Trucks in One

With the optional front spray bar and rear sprinkler nozzles, the same vehicle becomes both a sweeper and a water truck. On dry days, it sweeps and suppresses dust. On other days, it flushes roads or waters green belts. This is a major cost saver for fleets with limited budgets and multiple responsibilities.

12. Built with Heavy‑Duty, Field‑Proven Component

• Sanyo motors – reliable for continuous duty
• Schneider control switches – industrial grade, long life
• Winsboro solenoid valve sets and hydraulic cylinders – the entire hydraulic system comes from a single trusted brand, reducing compatibility issues and simplifying spare parts management
• Secondary engine – allows the sweeping system to run independently, extending main engine life and reducing fuel consumption during low‑speed or stationary sweeping
