The axle load scale, also known as the quantum mechanical dynamic axle weigher, Static weighing scale, is mainly composed of high-precision weighing sensors, weighing instruments, and short axle scales. The axle scale has a small footprint, can be used for both dynamic and static purposes, and offers multiple options for vehicle finishing. There are many types of axle scales, such as portable trailer scale, portable axle scale, electronic car scales, portable weigh pad, double table axle scales, etc. The Vehicle weighing scales hire displays the weight and total weight of two axle scales simultaneously. Two weigh pad scales are calibrated separately and have multi-point correction, greatly improving the accuracy of the car key digital scale. Portable car key digital scale are widely used for measuring, monitoring, and data management of incoming and outgoing materials in warehouses, factories, freight yards, storage terminals, workshops, ports, and other places. Suitable for digital car scales weighing and measuring vehicles such as cargo trucks, trailers, semi trailers, container trucks, etc.

The development history of digital car scales instruments:

In recent years, domestic independent brand portable digital car scales instruments have made great progress in both product and design. Compared to the high price of imported portable cat truck weight scale near me, domestically produced portable car key digital scale instruments have a significant advantage in terms of price. Due to the reference of mature foreign designs, the WS1101 car key digital scale instrument has surpassed foreign brands in terms of static comprehensive accuracy, sensitivity, and stability, in addition to high accuracy.

Illegal overloading is known as the first destroyer of highways, which not only seriously damages highways and bridge facilities, but also easily causes road traffic accidents, endangers the safety of people's lives and property, and seriously disrupts the order of the transportation market, causing abnormal development of China's automobile industry.Portable trailer scale is urgent to further strengthen the governance of illegal overloading in accordance with the law.

The new policy of overloading and overloading has been implemented since 2016, and there are new punishment standards for Vehicle weighing scales hire overloading. Starting from September 21st, the new standards will be implemented for truck overloading. The standards for determining the exceedance of trucks will be strictly implemented in accordance with the mandatory national standard "Limits for Dimensions, Axle Scale Load and Mass of Vehicles, Trailers and Car Trains" (GB1589-2016). The most significant change is the cancellation of the over limit and overload recognition standards for vehicles with a total weight of more than 55 tons, an average axle scale load of more than 10 tons, and cargo exceeding the factory marked load capacity of the vehicle. Simply put, in the past, overloading was determined based on the number of axles. For example, for a 5-axle truck, if the total weight of the vehicle and cargo exceeds 50 tons, it is suspected of illegal overloading transportation. According to the new standards, if a five axle scale truck exceeds 43 tons (with some models exceeding 42 tons), it is suspected of illegal over limit transportation.

For a long time, the transportation department has been responsible for overloading management based on vehicle axle scale load and road and bridge bearing capacity, while the public security department is responsible for overloading management based on the weight indicated on the driving license. In addition, in 2004, the country issued a mandatory standard "Limits for Dimensions, Axle scale Load and Mass of Road Vehicles" (GB1589), which proposed vehicle production standards. However, in actual implementation, each department still follows their own standards, resulting in issues such as inconsistent standards for overloading and overloading, and inconsistent standards for vehicle management and production, which have been strongly reflected by the public. A major breakthrough in the "Opinions" this time is the unification of the legal recognition standards for vehicle overloading and overloading, based on the newly revised "Limits for Dimensions, Axle scale Load and Mass of Vehicles, Trailers and Motor Trains" (GB1589). The weight limit for vehicles with six or more axles has been adjusted from 55 tons to 49 tons, achieving the unification of vehicle management and production standards, as well as the unification of law enforcement standards between transportation departments and public security departments.

Portable weighing instrument weighing accuracy:

1: Dynamic axle weigher, typically consisting of 2 boards, with an error of ± 3%;

2: Static weighing scale, with a static configuration error of ± 0.3% -0.5% for multiple boards according to the required vehicle model;

3: When weighing dynamically, the slower the speed, the better. Do not brake or stop abruptly, maintain a constant speed. The inertia and impact force of sudden braking make the car key digital scale weighing value unstable.

4: When the vehicle is weighed and the wheels have not yet left the portable trailer scale weighing platform, turning in the direction will affect the use of the sensor due to the torque.

5: Due to ground reasons, if the ground is soft, the vehicle cannot be evenly stressed when passing through the weighing instrument, which will greatly affect the weighing value.

Explanation of the operating environment of the digital car scales:

1: A hard and smooth cement road surface is required. Choose a flat solid base road surface without sand and gravel particles to place two portable weigh pad weighing platforms. Adjust the distance between the two weigh pad weighing platforms to be consistent with the wheelbase of the vehicle to be weighed..

2: Do not install the axle scale weighing instrument in places with high voltage and strong electronics, and do not use it in places with strong electronics and strong vibrations.

3: Avoid sudden temperature changes that may affect sensing devices.

Precautions for using portable weighing instruments:

1: Choose a flat and gravel free solid road surface to place the axle scale weighing platform, ensuring even contact between the weigh pad platform and the road surface. Keep the portable digital car scales instrument in the length direction of the axle scale weighing platform on a straight line perpendicular to the direction of vehicle travel. Adjust the distance between the two weigh pad weighing platforms to match the wheelbase of the vehicle to be weighed. If you are using a wireless portable digital car scales, also point the switch position of the axle scale weighing platform to the side where you will place the weighing instrument.

2: Tips for checking the even contact between the weigh pad weighing platform and the road surface: The installer steps on the four corners of the weigh pad weighing platform with both feet twice, using different forces to press and feel if the weigh pad weighing platform is shaking.

A portable digital car scales instrument measures the weight of each axle (or axle group) of a vehicle, accumulates it, and obtains the total weight of the vehicle. It can be used for both Static weighing scale and constant speed dynamic axle weigher. During dynamic weighing, the weighing instrument can automatically end and accumulate the total weight of the vehicle.

Tips for checking the uniform contact between the weigh pad weighing platform and the road surface with a portable axle scale weighing instrument:

1: The installation personnel steps on the four corners of the axle scale weighing platform with both feet twice, using different forces to press and feel if the weighing platform is shaking.

2: Take out the weighing instrument and place it in the position you think is suitable. If it is a wireless digital car scales, make sure that the selected position is on the side where the weighing platform switch is located, and the instrument is not more than 15 meters away from the axle scale weighing platform.

3: Turn on the power supply of the axle scale weighing platform separately (this step is required for wireless portable weighing instruments).

The method is to long press the switch button on the axle scale weighing platform until the signal indicator light on the axle scale weighing platform starts flashing and then release it. At this time, the power of the axle scale weighing platform has been turned on, and the signal process of the collection instrument has entered. Please turn on the instrument power within 1 minute, otherwise the axle scale weighing platform will automatically shut down if the instrument signal is not received within this time. Therefore, when you finish using the equipment, you only need to turn off the instrument power, and the axle scale weighing platform power will automatically shut down within 1 minute.
