Frequently Asked Questions (QDY 50t-33.5m A7 Foundry Crane Drawing Analysis)
Common technical questions on the 50t capacity, 33.5m span, 12m lifting height, cabin control, heat insulation shield, molten metal hot processing, and 2 units.
1. What is the application of this QDY foundry crane?
This QDY foundry crane is designed for molten metal hot processing in foundry operations, including furnace, ladle, and casting processes. It is used in steel mills, foundries, and smelting plants where molten metal needs to be transported safely and efficiently in a demanding high-temperature environment.
2. Why is a heat insulation shield required under the main girder?
The heat insulation shield protects the crane structure and electrical components from the extreme heat radiated by molten metal during furnace, ladle, and casting processes. It prevents heat damage to the main girder, extending the crane's service life and ensuring safe operation.
3. What are the advantages of cabin control on this foundry crane?
Cabin control provides the operator with a clear view of the working area and a comfortable working position, protected from the extreme heat and harsh environment of molten metal hot processing. This ensures precise and safe operation during furnace, ladle, and casting processes.
4. What are the power requirements for this foundry crane?
3-phase, 480V, 60Hz. The lifting motor (75 kW), trolley travel motor (11 kW), and crane travel motors (2 × 15 kW) all run on this configuration.
5. What does the model designation "QDY 50t-33.5m A7" mean?
QDY = Double Girder Ladle Crane (Foundry Crane); "50t" = 50-ton capacity; "33.5m" = 33.5-meter span; "A7" = ISO A7 duty class.
6. What is the significance of the 2-unit order?
The 2-unit order provides redundancy and increased operational flexibility in the foundry. Two cranes can work together or independently in the same workshop, ensuring continuous operation even during maintenance or peak production periods.
7. What are the workshop dimensions for this crane?
The workshop width is 35 m, the length is approximately 65~70 m, and the bridge top elevation is +16 m. The crane's 33.5m span and 12m lifting height are designed to fit within these dimensions for efficient molten metal handling.
