  • Modular design reduces the pressure of maintenance
    Modular design reduces the pressure of maintenance
    The control unit (including circuit boards) is common to the whole series, reducing maintenance difficulty and maintenance time.
    The pluggable circuit board makes the maintenance operation easier, while the circuit board adopts gold-plated connectors to avoid poor contact caused by plugging and unplugging, ensuring the reliability of the device.
  • Digitalization protects production safety
    Digitalization protects production safety
    The equipment status is transmitted to the cloud in real time, which enables real-time online monitoring of production equipment.
    The system proactively pushes fault information and maintenance advice to prevent sudden equipment failures and losses before they happen.
  • Energy saving and environmental protection
    Energy saving and environmental protection
    Hoisting mechanism of bridge cranes mostly is operated with high-speed movement. When the lifting mechanism is descending at high speed, the motor is in power generation state, and all the energy generated is fed back to the grid.
    The raw materials are all green, low energy consumption and long life components, and environmental factors are fully considered in product design, manufacturing, logistics and transportation.
APPLICATION
Case Study
Thyristor Digital Drive for high current motors
The maximum tonnage of the customer's crane is 500t, which requires a high-current voltage-regulating speed-regulating device, and most equipment on the market cannot meet the requirements.
10THD can be applied to large tonnage cranes and uses patented technology of digital triggering to ensure the passage of 25A~3000A current, while ensuring the durability of the equipment.
Thyristor Digital Drive for high current motors
High temperature resistant
In the steelmaking and ironmaking workshops, environmental temperature reaches up to 60 °C. When the air conditioner breaks down, the high temperature causes damage to the equipment and affects production.
10THD can work in the environment of -10℃~60℃, and the selected materials have high temperature resistance, and the equipment has independent channel heat dissipation device to ensure efficient production of the production line.
High temperature resistant
Reduce spare parts management costs
The factory has a lot of hoisting crane equipment, and the cost of purchasing spare parts is high. In order to avoid affecting production, there is a serious backlog of spare parts, and the cost of spare parts management remains high.
10THD consists of a power unit and a control unit, and the control unit (including the circuit board) is common to the whole series, saving spare parts purchase and management costs.
Reduce spare parts management costs
Frequent overcurrent alarms
Customer found that the control system was abnormal, and 10THD had frequent overcurrent alarms, and it was necessary to find out the cause of abnormality. Through digital system analysis, overload information and speed reduction will appear when an overcurrent alarm occurs. It is speculated that there is an object blocking the railway and affecting actual operation. After checking the crane railway, it was indeed found that there was sludge, and the system returned to normal after cleaning the foreign object on the railway.
