Maintenance of torque limiter (1)

Torque limiter plays an important role in lifting equipment, but no matter what machine is used, it needs regular maintenance. Next, let's take a look at the maintenance work of torque limiter.
The torque limiter can monitor and detect the working condition of the crane in real time. It has its own diagnostic function, fast alarm and safety control for dangerous conditions. With black box function, it can automatically record the dangerous working conditions during operation, and provide basis for accident analysis and treatment. What is its use and maintenance?
1. When the crane is powered on, the sensors such as weight, amplitude and height will send their respective signals to the host through shielded cables. The microprocessor in the instrument will automatically calculate and judge the input signals and various manually set lifting condition parameters. After processing, the weight, amplitude, height and other data will be displayed through the LCD screen, and the control signals will be transmitted to the intermediate relay Electrical appliances, continuous circulation.
2. The installation method of sensing force take-off mechanism is different due to different crane types, and the installation method is also different.
3. After using the torque limiter for a period of time, there will be more or less deviation. The debugging method is relatively simple. As long as you read the operation manual carefully and start debugging once or twice under the guidance of the manufacturer, you can basically know it well.
4. Many manufacturers do not provide circuit drawings to users for the sake of confidentiality, which undoubtedly brings certain difficulties to the maintenance personnel. Therefore, the trained personnel should learn from the manufacturer's after-sales service personnel as much as possible about the treatment and analysis methods of some common faults, and make records carefully, so as to be in case of emergency.
