Product Description
The Heavy-Duty YZS Series Four-Girder Foundry Crane is a precision-engineered overhead traveling crane specifically designed for demanding steel mill applications, featuring a robust four-girder/six-rail configuration with Q355B steel construction for superior thermal stability (operating range: -25°C to +200°C). Its dual-hook system combines a 320-ton main hoist with ladle-handling attachments and a synchronized auxiliary hook for steel pouring and slag transfer operations, achieving ±1.5mm/m positioning accuracy through proprietary two-stage assembly technology-initial dimension-locked welding followed by stress-relief reassembly. The crane delivers 12 m/min lifting speed with A7/A8 duty cycle compliance, powered by Schneider electrics and PLC-controlled winch trolleys (380V/50Hz). Certified to CE and ISO 4301-1 standards, it incorporates modular pre-assembly to reduce field installation time by 40% while maintaining ≤±3mm tolerance on gauge/diagonal/span dimensions. Ideal for ladle transfer, continuous casting, and refining areas, its secondary stress-relief processing enhances structural integrity by 35% versus conventional designs.
Application Scenarios
The Heavy-Duty Four-Girder Foundry Cranes are specifically engineered for critical metallurgical operations in steel plants and foundries. These industrial cranes primarily handle molten metal containers, including steel ladles and slag pots, performing essential functions such as ladle transfer between furnace and casting stations, precise molten metal pouring, and slag removal operations. With their high-temperature resistant design and dual-hook configuration, they facilitate continuous casting processes, secondary refining operations, and emergency metal containment in demanding environments. The cranes' enhanced structural stability and precision positioning capabilities make them indispensable for steel production lines, particularly in electric arc furnace areas, ladle furnace stations, and continuous casting platforms, where they ensure safe, efficient handling of heavy molten metal loads under extreme thermal conditions.

Our Advantages
1:Exceptional Load Capacity - Designed to handle extreme weights (up to 320 tons) with reinforced four-girder construction for superior structural integrity.
2:High-Temperature Resistance - Built with Q355B steel and heat-resistant components to withstand molten metal environments (up to 200°C).
3:Precision Control - Equipped with PLC automation and variable-speed winches for millimeter-accurate ladle positioning (±1.5mm/m).
4:Dual-Hook Efficiency - Synchronized main and auxiliary hooks enable simultaneous ladle transfer, pouring, and slag handling, optimizing workflow.
5:Enhanced Safety - Features load moment limiters, anti-sway systems, and emergency brakes for molten metal operations.
6:Long-Term Durability - Two-stage stress-relief assembly reduces welding deformation, extending service life by 30%+ compared to conventional cranes.
7:Customizable Configurations - Adjustable spans (19m-27m), lifting heights (15m-25m), and speeds (12m/min standard) to fit specific furnace/casting layouts.
8:Certified Reliability - Complies with CE, ISO 4301-1, and FEM 1.001 standards for metallurgical duty cycles (A7/A8).
Packaging & Shipping
Bridge Crane packaging and shipping involves disassembling main/end beams exceeding 12m into match-marked sections protected by structural steel frames and VCI anti-corrosion coating, with critical I-beam flanges guarded by reinforced edge protectors; electric hoists and precision components are oil-immersed, foam-cradled in ISPM15-compliant wooden crates with silica gel desiccants (RH≤40%), while runway rails undergo zinc-plating and palletization; all cargo is secured using certified 5-ton lashing systems with shock-absorbing EPE foam (≥80mm) and rubber isolators (Shore A 60±5), complying with width/height limits (≤3.5m non-escorted; ≤4.8m vehicle height); mandatory documentation includes bilingual packing lists, lifting point schematics, HS Code 84261990, EN 10204 3.1 material certificates, and GPS/shock-logger transit reports; final on-site verification requires laser-alignment checks (≤3mm/m beam straightness) and 500MΩ insulation testing, with Institute Cargo Clauses A insurance covering transport risks.
