This heavy-duty casting crane is designed for molten steel and foundry operations, offering capacities from 5 to 450 tons, with spans ranging between 7.5 and 35 meters. It effectively meets high-demand industrial lifting needs.
Built for molten metal handling, the crane features a thermal‑protective coating under its main girder and meets work duty classes up to A8, making it well-suited for hot, dusty environments with maximum stability and durability.
It operates on three‑phase AC power (typically 380 V, 50 Hz), functions reliably between –10 °C and +60 °C, and handles humidity up to 50 % at +40 °C—configurable further to match customer‑specific conditions.
The crane includes weight overload protection, buffering with high-durability polyurethane, limit switches for travel control, undervoltage protection, and an emergency stop system—plus multiple control modes like pendant, remote, or operator cabin control.
Absolutely. The crane is engineered for low maintenance with a robust, streamlined design featuring a no-weld U-shaped girder, smooth and accurate lifting, low noise levels, and easily interchangeable components for swift serviceability.
You can tailor auxiliary hook capacities, lifting heights (6 – 30 m), control methods, voltage specs, working classes (A5 to A8), color schemes, and even base materials like Q345 steel to meet distinct operational demands.
