In the harsh and high-temperature conditions of foundry and metallurgical operations, equipment must meet the most demanding safety and durability standards. Weihua’s foundry crane hook heat resistant solution is specially designed to handle molten metal and extreme environments with enhanced performance and reliability.
Weihua’s foundry crane hook heat resistant is engineered to endure high-temperature working conditions commonly found in steel mills, casting workshops, and smelting facilities. Manufactured with advanced materials and precision heat treatment processes, these hooks maintain structural integrity and load-bearing capacity even when exposed to intense heat.

1. Tahan Panas: Constructed with alloy steel or specialized heat-resistant materials, Weihua’s hooks withstand temperatures exceeding 300°C, ideal for ladle cranes and metallurgical operations.
2. Kekuatan Tinggi: With optimized forging and heat treatment, the hook provides excellent mechanical performance under heavy loads.
3. Safety Design: Equipped with a safety latch and designed with proper throat openings to prevent load slippage during operation.
4. Wear Resistance: Treated for enhanced surface hardness to resist abrasion in demanding environments.
5. Customizable Options: Available in single or crane double hook jenis, tailored for specific foundry crane applications.

In Duisburg, Weihua supplied heat resistant crane hooks for a ladle crane used in continuous casting operations. The hooks operate under temperatures around 400°C, successfully handling 150-ton molten metal ladles. The client praised the hooks’ performance and zero failure rate over two years of operation.
At CSN’s hot metal processing line, Weihua delivered a batch of foundry crane hook heat resistant components rated at 20 ton, specially treated for thermal resistance up to 450°C. The durability in South America’s humid and high-heat environment proved exceptional.
Weihua worked with Tata Steel on a major plant upgrade. Our double-hook heat-resistant assemblies were used in a 100-ton overhead crane. These hooks perform seamlessly in the blast furnace bay, where ambient heat reaches 350°C.
Weihua installed a series of heat-resistant crane hooks rated for -40°C to +500°C temperature range. Their use in extreme thermal cycles showcased our hook’s exceptional metallurgical strength and crack resistance.


Weihua is a globally recognized manufacturer of industrial cranes and lifting components. With decades of experience, our crane hook products are trusted in some of the world’s most demanding metallurgical environments. We offer not just equipment, but complete safety, dukungan teknis, and custom engineering solutions.
