Column-Mounted Cantilever Crane: The "Red Swinging Arm God of War" of the Metallurgical Workshop

Amid the steaming steel fires of the steelmaking workshop, the vermilion fixed-column cantilever crane stands tall like a "vertical heavy artillery" - the cylindrical column penetrates directly into the center of the earth, the cantilever beam is like a battle axe across the sky, and the 360° rotation radius covers an operating area of 10~30m. In the "extreme battlefield" of lifting molten steel ladles and transferring high-temperature billets, the hard-core logic of "fixed column load-bearing + rotating arm breakthrough" solves the triple dilemma of "narrow space, high temperature and heavy load" in the metallurgical workshop.

Technical Parameters:

Fixed Column Configuration: A single column supports a "ton-class cantilever."
✅ Mechanical Revolution: A Q345R forged steel column with a diameter of 1-2m is integrally molded, creating a "point load → circular diffusion" mechanical system. A single column can withstand over 3000kN (equivalent to a 300-ton static load), with 40% greater anti-overturning capacity than box-type outriggers, allowing it to seamlessly fit between the steel trusses of the steelmaking bay.
✅ Space Saving: The column occupies only 2-4m² of floor space, saving 80% of horizontal area compared to gantry cranes, freeing up valuable space for cranes, roller conveyors, and maintenance access. The foundation can be pre-buried in just 7 days during the renovation of the old plant.
✅ Seismic Locking: The column base features dual redundancy with a "spherical joint bearing + seismic anchor bolts," withstanding workshop-level 5 ground vibrations. Cantilever hook swing is ≤±15mm, and ladle casting alignment error is ≤5mm.

"Full-area Domination" in the Metallurgical Industry
🔹 Steelmaking Cross-Core Area: Lifting 120-ton ladles, the cantilevered boom spans the converter and continuous casting machine, collaborating with the overhead crane to achieve "zero-wait relay" for molten steel, increasing casting efficiency by 35% and reducing steel leak accidents to zero.
🔹 Rolling Heating Furnace Area: Lifting 80-ton hot billets, the boom extends 0.5m to the furnace side, replacing manual hooking and slashing workers' high-temperature exposure time by half.
🔹 Special Customization: Extra-long columns (≥18m) support blast furnace loading, and dual booms in parallel lift 150-ton slag pots. It can even accommodate circular plant tracks, turning "blind spots" in the metallurgical workshop into production growth points.
