The axle weighing scales, also known as the portable wheel scales or weight pads for trucks, is a type of non-standard axle scale. It can be further divided into dynamic axle weighbridge and fixed axle scales. Trade settlement between factories, mines, and axle scale weighing enterprises, as well as vehicle axle scale testing for transportation companies. The axle scale can achieve both non-stop weighing and axle stop cumulative weighing. Weighing is fast and accurate, easy to operate and use, simple to install and maintain, with the characteristics of low construction cost, convenient dismantling and relocation, and small axle scale area. Especially suitable for units with limited space, tight schedules, and strong maneuverability for axle scale load balancing.

The axle weighing scales is mainly used in some overload control units such as traffic control, highway bureaus, and road authorities. Axle weighing scales is also widely used in automobiles, ports, and mines. Axle weighing scales's significant feature is the light weight of the weigh pad plate, which has a plastic bridge and is very easy to carry. At the same time, the instrument also has a printing function, which can print the wheel weight, axle weight, approved load weight, overload weight, etc. of the car. At present, there are mainly two weight pads for trucks in the market: "wired car axle scale" and "wireless car axle scale". Due to the need for data cable connection to transmit relevant weighing data during overloading control, it is inevitable that the cable will be broken. Therefore, more overloading control units now choose to use wireless car axle scale that do not require cable connection for portable wheel scales.

Axle weighing scales are divided into wired axle scale /wireless axle scale. They are tools used to detect the axle load of cars, also known as weigh my truck near me, weight pads for trucks, portable wheel scales, dynamic axle weighbridge, and so on. It is mainly used in some overloading control units such as highway bureaus, and also has a certain range of applications in automobiles, ports, and mines.

The standard configuration of wired/wireless axle scale consists of a weighing body (including two weigh pad boards, junction box, etc.) and a weighing instrument. It is lightweight, easy to operate, and very portable. At the same time, the instrument panel also has a printing function, which can print the wheel weight, axle weight, approved load capacity, overload weight, etc. of the car. He is a good helper for checking cars.

A wired axle scale is a measuring device that measures the axle (group) weight of a vehicle separately through a weighing module (weighing board), and then accumulates to obtain the total weight (total weight) of the vehicle. The wired axle scale transmits relevant weighing data through a data cable connection, which is prone to wire breakage.

Wireless axle scale is a measuring device that measures the axle (group) weight of a vehicle separately through a weighing module (weighing board), and then obtains the total weight of the vehicle through accumulation. On the basis of wired connection, the wireless axle scale is improved by adding a wireless signal transmission device to achieve wireless transmission of measurement data, which is directly displayed on the monitor and is the choice of most overload control units.

The principle of the axle weighing scales:

The most important structure among them is the weigh pad platform and its sensors, and its working principle is worth exploring!

The working principle of the weigh pad platform of the weight pads for trucks is as follows: when the car tire is subjected to heavy pressure on the weighing platform, the weigh pad platform sensor will release a voltage signal, and the output signal size is proportional to the weight of the tire. The signal is transmitted to the amplifier for amplification, and then converted into a digital signal by the analog-to-digital converter for display on the monitor. The value obtained from a single board is the wheel weight of the car, while two boards are the axle weight. Based on the axle type of the car, the total weight of the car can be accumulated.

The working principle of the weighing sensor of the portable wheel scales is as follows: when the weighing platform is compressed and deformed, it will change the resistance value of the resistance strain gauge in the sensor, thereby changing the output of the signal.

Application of portable wheel scales:

1: Simple axle scale: used for raw material storage, cumulative production, internal settlement, etc. Due to the use of axle measurement method, the external dimensions of the weigh pad platform are much smaller than ordinary axle scales, and the corresponding land area is also much smaller, so the investment is very small; Due to its lightweight and easy mobility, the device also saves on installation and transportation costs.

2: Checking for Overloading: This portable wheel scales can be used by traffic management and road administration departments to inspect vehicles for overloading and overloading on highways, which is crucial for safe driving, protecting roads and bridges.

3: Safety performance testing: Portable wheel scales can be used as a car safety performance testing line to detect the weight of the wheels (axles) of the car. It mainly uses its dynamic axle weighbridge method, which not only saves the installation site of the testing line (but also saves site investment), but also greatly shortens the testing time and improves the testing efficiency due to the use of dynamic testing.

What should be noted when using a axle weighing scales?

1: The sensor of the axle weighing scales and the car wheel weight detector must be reliably connected and kept away from strong electric and magnetic fields. The sensor and the axle weighing scales should be kept away from highly corrosive objects and flammable and explosive materials.

2: Do not use the weight pads for trucks in areas with flammable gases or vapors.

3: In areas with frequent lightning strikes, reliable lightning arresters must be installed to ensure the personal safety of operators and prevent lightning strikes from damaging the weight pads for trucks and corresponding equipment.

4: The sensors of the axle weighing scales and the weigh my truck near me are both electrostatic sensitive devices. Anti static measures must be taken during use, and welding or other strong electric field operations are strictly prohibited on the weigh pad platform; During thunderstorm season, reliable lightning protection measures must be implemented to prevent damage to sensors and weight pads for trucks caused by lightning strikes, ensuring the personal safety of operators and the safe operation of weighing equipment and related devices.

5: Before plugging or unplugging the portable wheel scales and connecting it to external devices, the power supply of the portable wheel scales and corresponding equipment must be cut off first! Before plugging or unplugging the sensor connection wire, the power supply of the car wheel weight tester must be cut off (turned off) first! Before plugging or unplugging the communication link, the power supply of the weigh my truck near me and the upper computer must be cut off first!

6: The axle weighing scales cannot be overloaded. If this type of axle weighing scales is severely overloaded, its self-protection cannot avoid damage;

7: The use of weight pads for trucks/vehicle weighing instruments requires regular cleaning and maintenance of the humidity and dust in the operating environment; When it cannot be used for a long time (such as more than one month), power on inspection should be carried out according to environmental conditions to avoid moisture or other adverse gas erosion affecting reliability;

8: The axle weighing scales uses a weighing vehicle to maintain low speed, evenly weigh, and does not allow high-speed weighing and cheating by using sudden braking and other means. On the one hand, it can lead to inaccurate weighing and also affect the service life of the axle weighing scales;

9: Timely lubricate and grease the weight pads for trucks, regularly clean the debris on the sensor, and regularly grease the load-bearing steel ball of the weight pads for trucks sensor to prevent rust, inaccurate weighing or jumping phenomenon.

In short, in addition to following the above operation guidelines for correct operation, if the axle weighing scales or weight pads for trucks malfunctions or becomes disordered, remember to first cut off the power, contact the manufacturer or installation engineer for guidance and troubleshooting, and do not open the chassis on your own to avoid further damage.
