400 Ton Ladle Crane | Heavy Duty Metallurgical Overhead Crane for Steel Mill

400 ton ladle crane is a professional heavy-duty metallurgical overhead crane designed for high-temperature, high-load, and continuous-cycle working conditions in large steel plants and foundries. As the core handling equipment for steelmaking and continuous casting production lines, the 400t ladle crane is mainly used for lifting, 転送する, 位置決め, and pouring molten steel ladles, ensuring safe, 安定した, and efficient operation of the entire smelting process.

400 Ton ladle crane

Different from ordinary industrial overhead cranes, our metallurgical ladle crane adopts a high-temperature resistant, anti-fatigue and fully redundant safety structure. Rated A7 heavy-duty working class, これ 400 ton metallurgical crane can adapt to 24-hour uninterrupted cyclic operation, solving the harsh working pain points of molten steel transfer in modern large-scale steel mills.

とは何ですか 400 Ton Metallurgical Ladle Crane?

a 400 ton metallurgical ladle crane is a special overhead lifting equipment customized for high-risk molten metal handling scenarios. It undertakes the key process of transporting high-temperature molten steel ladles from converters, refining furnaces to continuous casting machines.

Equipped with dual independent lifting systems and multi-layer safety protection devices, the heavy duty 400 ton ladle overhead crane avoids molten steel splashing, ladle falling and equipment failure during high-intensity operation. It is an indispensable core equipment to guarantee the continuity and safety of steelmaking production.

Core Structural Features of 400 Ton Ladle Overhead Crane

The 400 ton ladle crane adopts a mature four-girder six-rail integral structure, which is the most stable structural form for super-large tonnage metallurgical cranes. The overall structure features uniform force bearing, strong anti-deformation ability and long fatigue life, fully adapting to long-term heavy-load operation.

• ◆ High-Strength Reinforced Main Girder: 主桁は高張力低合金鋼製, processed by integral welding and stress relief annealing. A professional high-temperature insulation board is installed at the bottom of the girder to isolate molten steel thermal radiation, effectively preventing structural deformation and material aging caused by long-term high-temperature baking.
• ◆ Dual Independent Lifting Mechanism: Configured with main and auxiliary dual lifting systems with independent transmission and control. The two mechanisms can work synchronously or independently to complete ladle vertical lifting, fine positioning and flip pouring, meeting diverse steelmaking process requirements.
• ◆ Anti-Derailment Travelling System: Adopts multi-wheel balanced travelling and corner driving structure, matched with automatic rail sweeping and anti-derailment limiting devices. The whole machine runs smoothly without impact or deviation under full 400-ton load.
• ◆ Heat-Resistant Forged Hook Assembly: The main hook is integrally forged from special alloy steel, with high temperature resistance, overload resistance and fatigue resistance. It can keep stable performance under frequent heavy-load lifting and high-temperature radiation.

Full Safety Protection System for 400T Ladle Crane

Safety is the primary design principle of metallurgical ladle cranes. 私たちの 400 ton ladle crane is equipped with a full set of redundant safety protection devices to eliminate hidden dangers in high-temperature and heavy-load operation:

• ◆ Dual Brake Safety System: Both main and auxiliary hoists are equipped with dual brakes. Once a single brake fails, the auxiliary brake will lock the heavy load instantly to prevent ladle falling accidents.
• ◆ Overload and Stroke Limit Protection: Built-in high-precision overload limiter and multi-group travel limit switches, which automatically cut off power and send alarm prompts when overloaded or over-stroked to avoid illegal operation damage.
• ◆ Anti-Sway and Anti-Fall Device: The professional anti-sway system effectively controls the swing amplitude of the ladle during operation; the trolley and travelling mechanisms are equipped with anti-fall locks to ensure stable operation in extreme working conditions.
• ◆ Real-Time Operation Monitoring System: It supports real-time monitoring of equipment load, 動作温度, running speed and fault data, realizing early fault warning and whole-life data traceability.
