- Weighing System
The wheel loader electronic scale is an electronic weighing device installed on the domestic or imported wheel loader to measure the load. It can provide various loading information such as single shovel value and cumulative value of the material being weighed, and print the list. While loading, it can dynamically and synchronously reflect the loading volume, helping customers to complete the weighing operation quickly and at low cost, and accurately load and unload. , to prevent overloading, improve work efficiency, is widely used in factories, mines, railways, ports and other bulk cargo handling operations. Loader electronic scale is the most common name for loader industrial weighing equipment in the industrial industry, also known as loader scale, loader scale, forklift scale, forklift electronic scale and so on.
The loader electronic scale is a kind of loader weighing equipment, which is integrated with the mechanical control part of the loader and realizes weighing during the loader operation. It realizes the weighing by converting the hydraulic pressure into the weight of the load in the bucket by monitoring the predetermined weighing position with a proximity switch. It has two different working modes: target mode and accumulation mode. According to the operator's choice, the load can be automatically accumulated or deducted from the target set value.
The Wheel loader electronic scale enables the loader to automatically weigh the material while loading it. It is suitable for automatic weighing and measurement of loaders (including forklifts), overload protection, workload management, etc. It can weigh coal or coke, non-ferrous ore, earthwork, granite or marble, sand, gravel bricks, industrial and civil waste, excavation materials and construction additives. Application places: wheel loaders such as mines, stations, ports, docks, factories, freight yards, etc.

The wheel loader scale is generally divided into two parts, the signal acquisition part and the signal processing and display part. The signal acquisition part is generally realized by sensors or transmitters, and the accuracy of signal acquisition is very important to the weighing accuracy of the loader.
Wheel Loader Weighing System
1. Static weighing system
It is often used for the modification of existing loaders or forklifts. Since there is no appropriate weighing equipment on site, and the user needs to measure for trade settlement, in view of the user's demand for modification costs, the static measurement method is usually selected. Can be used exclusively for ingredients.
The static weighing equipment consists of: pressure sensor (1 or 2, depending on the accuracy requirements) + ordinary weighing display instrument (optional printer if necessary) + installation accessories (pressure pipe or process interface, etc.).
General characteristics of static weighing:
1) When weighing each time, the position of the weighing bucket is required to be consistent to ensure the accuracy of the weighing, thus affecting the weighing efficiency;
2) The equipment has fewer functions, and many tasks need manual assistance, such as recording, calculation, etc.;
3) It is suitable for short-term workplaces and does not require a large amount of data processing;
4) Low cost, suitable for some self-employed units or small units;
5) There are few parameters involved, and the installation and debugging are more convenient.
2. Dynamic weighing system
For the loading measurement of large units such as stations, ports, and mines, a dynamic weighing system should be selected to meet the needs of rapid, continuous measurement and large-scale data management.
The dynamic measurement and weighing equipment mainly includes: pressure sensor (2 pieces) + dynamic control instrument (with printing function) + installation accessories.
The main functional characteristics of dynamic weighing equipment:
1) Cumulative loading, weight setting, display and overweight alarm functions;
2) Single bucket weight weighing, accumulation and display functions;
3) The truck model selection or input function, the truck number entry function;
4) Input function of operator, loader number and loading station code;
5) Operation time (year, month, day, hour, minute) recording function;
6) Basic job data storage, printing and query functions;
7) Adopt dynamic sampling and fuzzy algorithm to realize dynamic calibration and dynamic weighing, no need to stop the bucket, and automatic weighing during the lifting process;
8) Use the loader power supply for power supply.
9) Using dual hydraulic sensors and high-precision A/D converter, the accuracy is higher.
10) Automatic zero setting or manual zero setting can be set.
