Frequently Asked Questions (QDY 50/10t-25.5m-12m A7 Foundry Crane Drawing Analysis)
Common technical questions on the 50t main hook, 10t auxiliary hook, 25.5m span, 12m lifting height, cabin + remote control, full VFD, 300m travel, and 2 units same bay.
1. What is the application of this QDY foundry crane?
This QDY foundry crane is designed for molten metal handling in foundry operations. It is used in steel mills, foundries, and smelting plants where molten metal needs to be transported safely and efficiently. The dual hook configuration (50t main + 10t auxiliary) provides flexibility for different lifting needs.
2. What are the advantages of full VFD on this foundry crane?
Full VFD (Variable Frequency Drive) on all motions — hoisting, trolley travel, and crane travel — provides smooth acceleration and deceleration, precise load positioning, and reduced mechanical wear. For molten metal handling, this ensures safe and reliable operation with minimal risk of load swing or shock.
3. What is the significance of operating 2 units in the same bay?
Operating 2 units in the same bay requires coordinated control and safety systems to prevent collision. This configuration increases operational flexibility and throughput, allowing two cranes to work together or independently in the same bay for efficient molten metal handling.
4. What are the advantages of cabin + remote control?
Cabin control provides the operator with a clear view of the working area and a comfortable working position, while remote control allows the operator to move freely and control the crane from a safe distance. This dual control mode offers maximum flexibility for different operational needs in foundry environments.
5. What does the model designation "QDY 50/10t-25.5m-12m A7" mean?
QDY = Foundry Crane (Ladle Crane); "50/10t" = main hook 50t, auxiliary hook 10t; "25.5m" = 25.5-meter span; "12m" = 12-meter lifting height; "A7" = ISO A7 duty class.
6. What are the power requirements for this foundry crane?
3-phase, 380V, 50Hz. The main lifting motor (75 kW), auxiliary lifting motor (19 kW), trolley travel motor (7.5 kW), and crane travel motors (2 × 13 kW) all run on this configuration, with full VFD control on all motions.
7. What is the max wheel load for this crane?
The max wheel load is 502.6 kN for the long travel wheels and 186.3 kN for the trolley wheels. This ensures the crane can safely operate on the recommended rail sizes (P43 for trolley, QU80 for crane).
