Kailifeng Sinotruk HOWO washing and sweeping vehicle
Chassis Configuration
Model Base: Built on the Sinotruk HOWO chassis, renowned for its robustness and wide - spread usage in commercial vehicles. The specific model might be something like the HOWO T5G series, which provides a stable and reliable base for the upper - mounted washing and sweeping equipment.
Cabin Comfort: Features a spacious and ergonomically - designed cab. The cab is equipped with air - conditioning as standard, ensuring a comfortable working environment for the driver even in extreme weather conditions. It also has a well - laid - out control panel, with easy - to - reach switches and gauges, reducing driver fatigue during long - hour operations.
Powerful Engine: Usually powered by a heavy - duty engine. For example, it could be a Weichai engine, such as the WP7 series. These engines are known for their high torque output, which is crucial for both driving the vehicle on various terrains and powering the upper - mounted equipment. They meet strict emission standards, such as Euro VI, to ensure environmental friendliness.
Transmission System: Matched with a reliable transmission, like the Fast gearbox. These gearboxes offer smooth gear - shifting, with multiple gear ratios to adapt to different road conditions and load requirements. Whether it's driving on flat urban roads or hilly terrains, the transmission can optimize the engine's power output, improving fuel efficiency and overall performance.
Axle and Suspension Setup: Equipped with heavy - duty axles. The front axle is designed to handle steering and support the front part of the vehicle, while the rear axles are built to carry heavy loads. A multi - leaf spring suspension system is commonly used, providing excellent shock absorption and load - bearing capacity. This setup ensures stable driving and good handling characteristics, whether the vehicle is empty or fully loaded with water and garbage.
Frame and Fuel Tank: The frame is constructed from high - strength steel, ensuring durability and the ability to withstand the stresses of the upper - mounted equipment and the operation process. It has a large - capacity fuel tank, typically around 300L, which allows for long - distance operation without frequent refueling, suitable for continuous street - cleaning tasks in large - scale urban areas.
Tire Specification: Fitted with large - sized, high - load - capacity tires. For instance, tires of size 11.00R20 are common. These tires have deep tread patterns, providing excellent grip on wet and dry roads, ensuring driving safety during operation. Their robust construction also makes them resistant to wear and tear, reducing the need for frequent tire replacements.
Upper - Mounted Configuration
Operation Layout: Adopts a "two - side - brush + central - wide - suction - nozzle + high - pressure - water - spray" layout. The two side brushes are adjustable in angle and speed, effectively sweeping debris from the sides of the road towards the central area. The central wide - suction nozzle, combined with a built - in high - pressure water spray bar, can efficiently flush and suck up dirt, dust, and small garbage on the road surface. The left and right high - pressure side spray bars are used to clean curbs and hard - to - reach areas, enhancing the overall cleaning effect.
Sub - engine for Power: Equipped with a reliable sub - engine. Some models may use a domestic light - duty diesel sub - engine with a power output of around 75KW. This sub - engine is dedicated to driving hydraulic pumps, fans, and high - pressure water pumps for the upper - mounted cleaning equipment. It ensures stable power supply for the operation of various working devices, even when the main engine is not running at full capacity.
Hydraulic and Electric Control Systems
Hydraulic System: Utilizes high - quality hydraulic components. The hydraulic pumps are sourced from well - known manufacturers, providing stable and high - pressure hydraulic power. The solenoid valve group is used to control the flow and direction of hydraulic oil precisely, enabling smooth operation of the side brushes, suction nozzle lifting, and garbage bin dumping. In case of emergency or malfunction of the main hydraulic system, there is usually a backup manual hydraulic operation mechanism to ensure that key functions can still be carried out.
Electric Control System: Features an advanced PLC - based control system. All operations, such as starting and stopping of the side brushes, high - pressure water spray, and suction fan, can be easily controlled through a control panel in the cab. The system also has an intelligent fault - diagnosis function, which can quickly identify and report any problems in the electrical or mechanical components, facilitating maintenance and reducing downtime.
Water System Details
High - Pressure Water Pump: Equipped with a high - performance high - pressure water pump. Some models may use an imported water pump from brands like Comet. The pump can generate a high - pressure water jet, with a pressure of up to 150Bar and a flow rate of around 120L/min. This powerful water jet can effectively remove stubborn dirt and stains on the road surface. The water pump is protected by multiple safety devices, including a pressure - relief valve and an over - temperature protection device, to ensure its long - term and stable operation.
Water Tank and Pipeline: The water tank is made of high - quality stainless - steel material, which is corrosion - resistant and has a large capacity, usually around 8 - 10 cubic meters. A low - water - level sensor is installed in the water tank, which will send an alarm signal to the driver when the water level is low, preventing the water pump from running dry. The high - pressure pipeline is made of high - strength and corrosion - resistant materials, ensuring the safe and stable transmission of high - pressure water.
Spraying Nozzles: The vehicle is equipped with a variety of spraying nozzles. The central suction nozzle's water spray bar and the side spray bars are fitted with special - designed fan - shaped nozzles. These nozzles can spray a wide and uniform water curtain, with a total spraying width of not less than 4m. In addition, there are also high - pressure rotating nozzles for cleaning specific areas, such as sewer inlets and manhole covers.
Garbage Bin and Recycling System
Garbage Bin Structure: The garbage bin is made of thick stainless - steel plates, ensuring durability and resistance to corrosion. It has a large - capacity design, typically around 5 - 7 cubic meters. The garbage bin adopts a tilting - type structure, and the maximum tilting angle can reach 45 - 50 degrees, facilitating easy dumping of garbage. Inside the garbage bin, there is an anti - overflow device to prevent sewage from overflowing during the suction process, and a high - pressure spray cleaning device to clean the bin after dumping.
Sewage Recovery: The central wide - suction nozzle has a large suction - mouth diameter, usually around 200mm. It is designed to have a high - efficiency sewage - recovery function. The built - in high - pressure water spray bar can first loosen the dirt on the road surface, and then the powerful suction force of the fan can quickly suck up the sewage and garbage, with a high sewage - suction rate to minimize secondary pollution.
Safety and Auxiliary Configurations
Safety Features: Equipped with an ABS braking system to ensure stable braking performance. There is also a reverse - alarm and a rear - view camera system, which provide clear visibility for the driver when reversing, reducing the risk of accidents. The vehicle has multiple safety protection devices for the upper - mounted equipment, such as emergency stop buttons, limit - switches for the lifting of the garbage bin and the extension of the side brushes, to prevent equipment damage and ensure operator safety.
Auxiliary Equipment: Installed with a high - definition monitoring system. Cameras are placed at key positions, such as the side brushes and the rear of the vehicle, and the images are transmitted to a monitor in the cab. This allows the driver to monitor the operation status of the equipment in real - time and adjust the operation as needed. An LED warning light bar is installed on the top of the vehicle to enhance visibility during operation, especially in low - light conditions.
