1. The QDY double beam bridge loading crane is one of the main equipment in steel manufacturing continuous casting technology. Mainly used for smelting metal transport, casting, and hot metal loading.
2. The QDY double beam casting crane consists of a boxed bridge frame, a hook, a crane walking mechanism, and an electrical system. The main hook uses a load tool as the lifting device to lift the ladle, and the auxiliary hook cooperates with the main hook to complete the pouring of molten steel and steel slag, as well as other auxiliary lifting.
1. Adopt Siemens PLC and Siemens frequency converter for control and drive. Meanwhile, Profinet is used for communication between PLC and frequency converter. It is equipped with communication detection function, which can detect the working status of each site in real time.
2. A monitoring system has been installed to monitor the working status of the crane in real-time.
3. The lifting mechanism of the ladle crane adopts a redundant system design to ensure the safety and reliability of lifting liquid metal.
The traveling mechanism and main electrical equipment of the QDY double beam bridge type ladle crane are installed in a box girder, which is insulated with rock wool and equipped with an air cooler inside. In order to reduce the thermal radiation of molten structural components, thermal baffles are installed along the span direction at the bottom of the beam
4. It has wireless transmission and electronic scales, which can transmit the weight of liquid metal in real time.
5. Each crane is designed with an electrical room, which is equipped with an electric fan to ensure the safe and reliable operation of electrical equipment.
The lifting mechanism of the 6.250t ladle crane adopts a planetary reducer structure. If an electric motor malfunctions, it can still complete the lifting work in a short period of time.
7. The mother child car has achieved unmanned automatic bag lifting, saving costs.
8. The overall design is lightweight and compact in structure.
9. Low height, light weight, small hook limit, and large working range.
10. High quality parts, durable, safe and reliable.
11. Less maintenance and repair costs.
12. The total power of the crane is small and the energy consumption is low.
13. Frequency control, smooth lifting and low impact
