For a long time, the forklift truck was only a tool for lifting and transporting goods. In order to weigh the goods by the way in the lifting and transporting process, a weighing console was set up on the electric forklift truck, and the weighing instrument was installed on the console. The data lines installed on the lower parts of the two fork support legs were connected with digital instruments. When the elastic body with digital weighing was subjected to the force from the force direction (such as the gravity of goods), The elastic body produces corresponding micro-deformation, which is transmitted to the digital weighing instrument through the force transmission mechanism. The gravity signal output by the sensor is amplified and filtered, and 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 gantry 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 through wireless.

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 are becoming more and more obvious, and the popularity of Electronic scales in stacking forklifts is increasing, which makes forklifts 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 the electronic scale of battery forklift in various environments, linear compensation, zero compensation and temperature compensation, as well as sensing dynamic design are generally added to the bridge circuit of the strain gauge for forklift weighing. 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.

Impact overload devices are arranged at the front end and upper end of the weighing sensor, so that the front end of the weighing fork of 300kg-500kg is impacted, the left and right sides of the full-load range are loaded, and the inertia force of 300-3000kg is applied from a height of one meter to ensure the accuracy within 1d. Ensure the weighing performance and quality of the balance forklift electronic scale in man-made loss.
