Comprehensive Product Introduction: Dongfeng Tianjin Guardrail Cleaning Truck | DFAC 4×2 Guardrail Cleaning Truck with 12 Cubic Meter Tank Capacity

I. Product Overview

The Dongfeng Tianjin Guardrail Cleaning Truck is a heavy-duty, multi-functional municipal vehicle engineered for high-efficiency road maintenance and sanitation tasks. Designed to tackle the toughest cleaning challenges, this unit excels at cleaning median barriers on highways and expressways, as well as washing W-beam guardrails along roadside edges. Its robust design incorporates a powerful onboard power system, allowing it to perform intensive cleaning operations independently of the chassis engine. Beyond guardrail maintenance, this truck serves as a versatile piece of municipal cleaning equipment, integrating multiple functions such as high-pressure washing, dust suppression, and greening irrigation, making it an indispensable asset for highway departments and municipal works.

II. Core Parameters

The following table outlines the critical specifications of the Dongfeng Tianjin Guardrail Cleaning Truck, highlighting its powerful performance and operational efficiency.

III. Dimensions, Materials & Design Philosophy

The design of the Dongfeng Tianjin cleaning truck focuses on maximizing durability, operational stability, and multi-scenario adaptability. The vehicle dimensions are engineered with a substantial wheelbase to accommodate the large 12,000-liter water tank while ensuring stability during high-speed travel and cleaning operations. The water tank is constructed with high-grade materials, typically featuring a side wall thickness of 4mm and a bottom plate thickness of 5mm, using high-strength carbon steel or optional 304 stainless steel to ensure corrosion resistance and longevity for heavy-duty use. The design philosophy prioritizes "one truck, multiple uses." It integrates a front wash bar for road cleaning, a rear water sprinkler for dust suppression, side sprays for greening irrigation, and a remote-controlled water cannon for landscape watering, all while maintaining the core function of median barrier cleaning.

IV. Detailed Structure: Engine, Transmission, Axles, and Chassis

This model boasts a robust configuration ensuring powerful cleaning and smooth operation.

• Main Engine & Power System: The chassis is powered by a Cummins 230 horsepower diesel engine, compliant with Euro VI emission standards. This provides ample power for the vehicle's road travel and can optionally power auxiliary systems when needed.

• Independent Auxiliary Power: This unit is equipped with a self-contained auxiliary engine, which independently drives the high-pressure hydraulic system. This design ensures that the cleaning intensity does not affect the driving performance, allowing the main engine to focus on mobility while the auxiliary engine provides consistent power to the brushes and water pump.

• Transmission & Drive System: It features a heavy-duty manual transmission matched to the Cummins engine. A power take-off (PTO) drives high-pressure hydraulic pumps, powering the brushes and water pump, ensuring reliable power delivery without belt slippage.

• Axles & Chassis: The vehicle utilizes a heavy-duty 4×2 axle configuration, consisting of a front steer axle and a rear drive axle, supported by a reinforced double-layer frame. This provides the necessary load-bearing capacity for the 12-ton water tank and ensures stability during high-speed brush contact with guardrails.
