III. Dimensions, Materials & Design Philosophy
The design of the Sinotruk Howo cleaning truck focuses on maximizing operator comfort, structural durability, and cleaning precision. The vehicle dimensions are engineered to accommodate a large-capacity water tank while maintaining stability during extended boom operations. The water tank features a capacity ranging from 8 to 10 cubic meters, constructed from high-quality carbon steel with specialized anti-corrosion coating to ensure long service life when storing water for cleaning operations. The design philosophy prioritizes vertical structure cleaning efficiency. The centrally mounted telescopic cleaning arm, combined with multi-angle nozzle technology, ensures complete coverage of sound barriers regardless of their height or angle, effectively removing accumulated dust, exhaust residue, and biological growth that can reduce acoustic effectiveness.
IV. Detailed Structure: Engine, Transmission, Axles, and Chassis
This model boasts a robust configuration ensuring powerful performance and smooth operation.
Main Engine & Power System: The chassis is powered by a Weichai 220 horsepower diesel engine (Model WP4.6NQ220E61), compliant with National VI / Euro VI emission standards. This engine provides excellent power output for both road travel and supporting auxiliary systems, ensuring reliable performance even under heavy loads.
Auxiliary Engine (Independent Power): The cleaning mechanism is powered by a dedicated Jiangxi Isuzu (JMC) or equivalent auxiliary engine, typically rated between 80-90 horsepower (such as the common 87 HP model). This independent power source ensures that cleaning intensity and water pressure remain consistent regardless of the chassis engine speed, preventing operational interference.
Transmission & Drive Options: The truck is available with multiple transmission configurations from Shanxi Gear (Fast Gear) , including 8-speed and 12-speed manual transmissions. These options provide smooth shifting, high transmission efficiency, and optimal torque management for both highway travel and low-speed cleaning operations.
Axles & Chassis: The vehicle utilizes a heavy-duty axle configuration with a 3.6-ton front steer axle and an 8-ton rear drive axle, supported by a reinforced heavy-duty frame. This robust suspension and axle setup provides exceptional load-bearing capacity for the water tank and ensures stability during boom extension and retraction.
Driver Comfort & Control: The truck features the Howo 2250 wide-body cab with four-point suspension, offering excellent spatial comfort and reduced vibration. Standard equipment includes an original air conditioning system, multi-function steering wheel, cruise control, and a comfortable air suspension driver's seat, reducing operator fatigue during long working hours.
V. Product Features & Manufacturer Advantages (Chengli Group)
The Sinotruk Howo Sound Barrier Cleaning Truck is packed with advanced features, backed by the manufacturing excellence of Chengli Group.
Product Features:
Specialized Cleaning Arm System: The truck features a telescopic and rotating cleaning arm with an operating reach of 3 to 5 meters. This flexibility allows operators to easily adjust to different sound barrier heights and positions, ensuring effective cleaning of both straight and curved sections.
High-Performance Water Pump: Equipped with a German Pinfu (or equivalent high-quality brand) high-pressure water pump, the system delivers pressure ranging from 10 to 20 MPa and flow rates of 100 to 200 Liters per minute. This generates a powerful water jet capable of removing stubborn road grime and exhaust deposits.
Multi-Angle Nozzle Technology: The cleaning head features multi-angle nozzles designed for comprehensive coverage of sound barrier surfaces. This ensures that water reaches all profiles of the barrier, including recessed areas, achieving high-efficiency cleaning with no dead spots.
Extended Hose Reel System: A 20-30 meter high-pressure hose reel is included, allowing operators to perform spot-cleaning or reach areas beyond the arm's normal range, significantly enhancing operational flexibility.
Operational Safety: The system is designed for stable operation at height, and the rear is fitted with safety markings and lighting for road use during low-light conditions.
