The forklift scale of electric stacker is a Weighing system composed of precision weighing sensor and intelligent digital display instrument on the basis of electro-hydraulic lifting forklift. The electronic forklift scale realizes the ingenious combination of forklift and electronic weighbridge, and the weighing data can be displayed automatically every time. The weighing pallet stacker has the advantages of light weight, low body, light operation, wide field of vision, solid frame design, strong bearing capacity, balanced lifting, electric braking of motor output shaft and lead-acid traction battery to ensure long-term work.

It is transmitted to the digital weighing instrument through the force transmission mechanism. The gravity signal output by the sensor is amplified and filtered, and then sent to the A/D converter to be converted into a digital signal. The weight value is calculated by the microprocessor according to the mechanical mathematical model, and the weighing data is prompted to be read when the forklift mast is vertical. The digital weighing LED displays the results, and the real-time data is uploaded to the computer control room by the weighing instrument wirelessly. Now it is widely used in short-distance transportation and warehousing of goods in stations, docks and large and medium-sized enterprises. With the development of market economy, the position and role of logistics in economic development is becoming more and more obvious, and the weighing popularity of electric forklift is getting higher and higher, which makes forklift have multiple functions of handling, lifting and weighing, thus greatly improving the working efficiency and warehouse management level.

In order to ensure the measurement accuracy of forklift weighing in various environments, linear compensation, zero compensation and temperature compensation, as well as sensing dynamic design are generally added to the bridge circuit of forklift weighing strain gauge. At the same time, in order to ensure the accuracy of remote excitation of the sensor, two wires are generally output to the weighing instrument at both ends of the excitation of the strain gauge to calculate the loss compensation of the excitation voltage during long-distance transmission. When adjusting or replacing the digital weighing sensor and the digital weighing instrument, it is directly adjusted in the weighing instrument without adjusting the angle difference through the junction box, which greatly improves the simplicity of regular inspection and maintenance of weighing and the accuracy of commercial measurement.
