| The quantity of a single cleaning brush | 55 |
| Cleaning height（mm） | ≥1200 |
| Cleaning principle | Adopt the cleaning process of two flushes and two brushes, cleaning both sides simultaneously to make the cleaning more thorough.
Cleaning process: Firstly, the two rows of water spray pipes in front of the brush rollers spray water to fully pre-wet the guardrail. During the process of the vehicle body moving forward, the two rows of brush rollers in the middle scrub the guardrail successively. Finally, the two rows of water spray pipes behind the brush rollers spray water to wash away the remaining dust. |

Vehicle performance and characteristics
This 4 - cubic - meter guardrail cleaning vehicle has a cleaning diameter of over 600mm. It can conduct special operations on large - diameter traffic facilities such as anti - collision barrels, road and bridge curbstones, road and bridge cement fences, and cement piers, with a wide range of applications.
The water tank capacity of this 4 - cubic - meter guardrail cleaning vehicle reaches 4 tons, which is about twice that of similar vehicles. It can operate continuously for 3 - 4 hours, avoiding the waste of time and cost during repeated water - filling processes and greatly improving the actual operation efficiency.
The operating speed of the guardrail cleaning vehicle reaches 3 - 15km/h, which is 2 - 3 times the actual operating speed of similar vehicles.
This guardrail cleaning vehicle is equipped with a high - tech intelligent operating system, in line with mechanical intelligence. It realizes the automation of mechanical operation, which can be completed with one key.
In addition to cleaning the widely used Beijing - style guardrails, this guardrail cleaning vehicle can also conduct one - time cleaning without dead angles on large - thickness plastic - steel guardrails, inclined - plate anti - glare guardrails, etc.
This guardrail cleaning vehicle can be optionally equipped with multi - functional devices such as a water - sprinkler operation structure, a video monitoring system, a high - pressure water gun structure, and a garden long - range spraying system, fully realizing the multi - purpose use of one vehicle with complete functions.
Start the auxiliary engine. The auxiliary engine drives the hydraulic oil pump, and the brush - rolling mechanism is opened by controlling the horizontal telescopic cylinder.
The height of the brush - rolling mechanism is adjusted by controlling the lifting cylinder.
The outer brush - rolling is made to swing by 90° by controlling the brush - rolling swing cylinder. The vehicle is moved close to the guardrail so that the brush - rolling can clamp the guardrail.
The distance between the outer brush - rolling and the guardrail is controlled by adjusting the brush - rolling distance adjustment cylinder. After the position is adjusted, the high - pressure water pump and water - way control components are controlled to operate, and the high - pressure nozzles and low - pressure nozzles start to spray water. At the same time, the brush - rolling motor drives the brush - rolling to start rotating, and the guardrail cleaning vehicle starts the guardrail cleaning operation. When the operation reaches the end of the guardrail, the guardrail cleaning vehicle can directly drive away from the guardrail.
When the guardrail cleaning vehicle needs to drive away from the middle of the guardrail or transfer to another site, the outer brush - rolling is made to swing by 90° by controlling the outer brush - rolling swing cylinder, and then the vehicle is driven away from the guardrail.
