Product description:

LD Series loader electronic scale (forklift electronic scale) is a high-precision weighing product independently designed, developed and produced by Lidong Weighing Co., Ltd., which is suitable for dynamic weighing and measurement of railways, mines, quarries and sand yards. On the basis of not changing the weighing structure of the original loader (forklift), the electronic ground scale manufacturer adds the special loader (forklift) weighing equipment for Lidong weighing, The hardware and software are in line with the electronic weighing instrument to refuse overload and underload, and improve the loading and unloading efficiency and efficiency.

Operating principle of electronic weighbridge:

Two pressure sensors are installed on the loader (forklift), and the position sensor controls the effective value of the signal collected by the pressure sensor, that is, by measuring the pressure difference between the two ends of the lifting pressure cylinder piston of the wheel loader, the pressure value is converted into a weight signal using digital analog software, and the weight value is displayed after data calculation and processing by a microcomputer processor, And print out the data as required. The weighing process is full dynamic measurement. The precision of this product is strictly in accordance with the provisions of the international metrology organization OIMLR51Y (B), and the weighing error can be ± 1%. All kinds of loaders, whether imported or domestic, can be installed.

Product structure of electronic weighbridge:

LD series special loader electronic scale (forklift electronic scale) is composed of high-precision micro sensor (designed with large diameter oil hole, even if there are some impurities in the hydraulic oil, the sensor will not be blocked and scrapped; temperature self adjustment compensation, temperature drift control), contact proximity position sensor All Chinese intelligent menu type microcomputer display (high-strength molded case, good sealing, shockproof, dustproof, friction resistant, waterproof, strong anti-interference ability, suitable for various harsh working environments).

Structure of Chinese intelligent menu type microcomputer display (weighing instrument)

Microcomputer display: large screen dot matrix graphic display, which can display any graphic or character content, has the function of pinyin input of Chinese characters, anti glare design, clear vision under direct sunlight, and background light function to ensure night work, tunnel work, such as underground coal mine loader (forklift) weighing. In addition to displaying the weight and cumulative weight of materials in the tipper, the display also displays information related to weighing, such as company name, train number, truck number, material type, etc; At the same time, the electronic scale displays the instant time and date, and can set the loading limit value of the train or truck.

● Keyboard: used when users operate microcomputer display (weighing instrument), such as inputting English letters, numbers, pinyin and other relevant information.

● Fluorescent screen needle printer: the instrument is equipped with an intelligent micro dot matrix printer, which can print weight, cumulative information, vehicle number, unit name and other relevant information.

● Color screen thermal printer: the instrument has its own thermal printer, which is designed as an integrated whole, does not occupy the cab space, and can print the weight, cumulative information, vehicle number, unit name and other relevant information. Advantages: fast paper feeding speed, low noise, no need to change ribbon, extremely convenient paper loading, which solves the problem of common

The printer has the defect of poor paper feeding due to the low temperature of the weighing environment. The color screen weighing instrument has less internal wiring, low failure rate and higher stability.

● Memory battery: there is a RAM battery in the instrument, and the stored data can still be retained when the scale is turned off.

Functions and features of the product:

● Performance assessment can be realized, and daily, weekly and monthly report statistics can be realized by vehicle number, so as to improve the work efficiency of workers.

● (Color screen) realizes the function of general printing, which solves the problem of customers loading multiple vehicles and printing the loading data of multiple vehicles at the same time;

● Microcomputer control, full dynamic measurement, forklift need not stop during lifting, simple operation, can effectively prevent overload and underload;

● Full dynamic Chinese intelligent voice reading function, reminding the driver of overloading, bucket sticking, data error and other phenomena, and eliminating the driver's wrong operation;

● Setting and display of cumulative loading weight, with total overload alarm and single shovel weight alarm functions, which is convenient for controlling weight loss and overload;

● Microcomputer control, which can display real-time weighing results (single bucket weight, cumulative weight), vehicle type selection, vehicle number, operator, material name, loading station code, operation time (year, month, day, hour, minute), double oil circuit and multi-party detection, with high intelligence and comprehensive and accurate data;

● All Chinese characters function Pinyin input, operation basic data storage, printing function (loading time, goods name, weight, car number and other data)

● The screen and keyboard are equipped with backlight function, which is convenient for night operation, tunnel operation, such as underground coal mine loader (forklift) weighing;

● IP class has strong anti-interference ability, and is suitable for various harsh working conditions and interference signals of railways, highways, freight yards;

● Speed compensation function to ensure the accuracy of electronic scales for different drivers with different driving habits;

● The temperature compensation function ensures the accuracy of the electronic scale when working at low temperature and high temperature.
