General purpose overhead crane
QDY Type Casting Double Girder Overhead Crane
Product Overview
The Weiyuan QDY Type Casting Crane is a heavy-duty, specialized double girder overhead crane engineered to operate in the harsh, high-temperature environments of steel mills and foundries. Designed specifically for lifting and transporting ladles of molten metal, this crane is the backbone of the metallurgical and casting process. It features a robust structure, heat-resistant components, and multiple layers of safety protection to ensure maximum reliability and security when handling critical, high-temperature loads. With advanced controls and durable construction, the QDY Casting Crane is built for performance and safety in the most demanding industrial settings.
Product Advantages
Superior Heat Resistance
Engineered to withstand extreme heat, the crane is equipped with thermal insulation layers protecting the main girder and critical components from radiant heat. The electrical systems and motors are designed for high-temperature work environments, ensuring reliable operation even when handling molten metal.
Heavy-Duty and Robust Structure
The double girder design provides exceptional strength and stability, capable of handling large-capacity loads up to 800 tons. The trolley is equipped with a main and auxiliary hook, allowing for both primary lifting and auxiliary operations like tilting the ladle, enhancing operational flexibility.
Multi-Layered Safety Protection
Safety is the highest priority. This crane includes a comprehensive suite of safety features, such as dual braking systems on the main lifting mechanism, overload limiters, temperature alarms, emergency stop functions, and heat-resistant cables, to guarantee secure handling of molten metal.
Reliable and Precise Control
The crane is typically operated from an air-conditioned cabin, which protects the operator from the harsh external environment. Advanced control systems, including options for variable frequency drives (VFD), allow for smooth, precise, and stable movement, minimizing load sway and ensuring accurate pouring.
Durable, High-Performance Components
Built with top-tier components from trusted brands like Schneider and Siemens, the QDY crane is designed for longevity and minimal downtime. The winch trolley, motors, and gearbox are all engineered for A5-A6 heavy-duty work cycles, providing consistent and powerful performance.
Application Scenarios
Steel Mills and Smelting Plants
The primary application for the QDY crane is in steel mills for the transportation of ladles filled with molten iron or steel from the blast furnace or electric arc furnace to the continuous casting machine or ingot molds.
Foundry and Casting Operations
Essential for foundries, this crane handles the lifting and pouring of molten metals such as aluminum, copper, and iron into molds to create castings, ensuring a smooth and safe production process.
Metallurgical Industry
Used in various metallurgical processes that involve the handling of liquid metal, including refining, alloying, and transferring between different processing stations. It is a critical piece of equipment for any large-scale metal production facility.

FAQ
Q: What is a casting crane, and how does it differ from a standard overhead crane?
A: A casting crane (or ladle crane) is a specialized heavy-duty overhead crane designed specifically for transporting molten metal in foundries and steel mills. It differs from standard cranes by having enhanced safety features, superior heat resistance, and a more robust structure to handle the extreme temperatures and critical nature of lifting liquid metal.
Q: What safety features are included for handling molten metal?
A: Our QDY casting cranes are equipped with multiple layers of safety. This includes a dual-braking system on the primary lifting mechanism, overload limiters, heat shields to protect the girder and trolley, insulated hooks, and high-temperature resistant cables. All features are designed to ensure fail-safe operation.
Q: What is the purpose of the main and auxiliary hooks?
A: The main hook is used for the primary lift of the ladle. The auxiliary hook, which operates independently, is used for ancillary tasks such as tilting the ladle to pour the molten metal or for maintenance and other smaller lifting jobs. This dual-hook system provides greater operational control and efficiency.
Q: Can this crane be operated remotely?
A: While the standard and safest method of operation is from a climate-controlled cabin, we can equip the crane with a wireless remote control as a supplementary or backup control method, depending on your operational safety protocols.
Q: How does Weiyuan ensure the quality of such a critical piece of equipment?
A: With nearly 40 years of manufacturing experience and a history of supplying to major industrial players, Weiyuan builds cranes to the highest international standards. Our QDY casting cranes are designed by expert engineers, built with certified materials, and undergo rigorous testing and inspection, including load tests and safety system checks, before shipment. A comprehensive quality report is provided with every crane.
