Digital Control Averaging Leveling Beam for Precise Asphalt Paving in Engineering Projects

The application fields of ultrasonic balance beams are quite extensive, mainly including the following aspects:
1.Highway construction
Expressways: Ensure the flatness and quality of expressway pavement and improve the comfort and safety of driving.
National highways and provincial highways: Provide high-quality paving effects for various trunk highways.
2.Urban roads
Main thoroughfares: Enhance the flatness of urban main thoroughfares and reduce the bumpiness of vehicle driving.
Secondary arterials and branch roads: Improve the overall quality of the urban road network.
3.Airport runways
Aircraft takeoff and landing areas: Ensure the flatness of the runway and meet the strict requirements for aircraft takeoff and landing.
4.Large parking lots
Provide a flat ground for parking lots to facilitate vehicle parking and driving.
5.Industrial park roads
Meet the needs of industrial transportation and vehicle passage and improve the durability and flatness of the roads.
6.Port terminals
Dock operation areas: Ensure the flatness of the dock ground, which is conducive to the operation of cargo handling and transportation equipment.
7.Roads around sports stadiums
Provide good traffic conditions for sports events.
In conclusion, in all engineering projects with high requirements for pavement flatness, ultrasonic balance beams may be applied to improve the working effect of asphalt pavers.

Chinese controller features

1. It adopts digital control mode, and forms a control network with sensors through the CAN bus protocol. It can be compatible with various CAN digital sensors on the paver, such as longitudinal slope, transverse slope, etc., and has strong scalability.

2. The LCD screen displays real-time data, and all operation interfaces are in Chinese or graphical prompts, making it easier to master and more convenient to use.

3. The system has a self-diagnosis function, and the faults of the system are clear at a glance on the display screen.

4. It is completely interchangeable and universal with the same type of imported brand products, and can be used for paver, milling machine, grader and other equipment.

Ultrasonic Sensor Features

Ultrasonic sensors: 6 in total. They all use original imported military-grade high-power probes, which can be exchanged at will. The installation height is 35 cm from the ground, and the last one is about 50 cm from the newly paved asphalt surface.

1. The ultrasonic slipper sensor consists of 6 ultrasonic probes, including 5 test probes and 1 environmental compensation probe, with a large detection surface;

2. It is used on the balance beam to increase the amount of test data. The five independent probes of the sensor work at the same time, and only three data close to the actual detection value will be used, so as to obtain the average value and make the road smoother;

3. It completely replaces the G176 contact slope gauge to detect the steel wire or curb benchmark, so that the leveling system can eliminate the influence of steel wire vibration and sliding rod drop on the smoothness of the road surface.
