Ladle Handling Crane

Redundant Safety Design: The main hoist mechanism incorporates two independent drive units, enabling the crane to complete one working cycle with a rated load even if one unit fails. The rope drum is fitted with a safety brake, achieving a braking safety factor of no less than 1.25, significantly enhancing operational safety.

High-Temperature and Radiation Resistance: The main girders and the lifting beam are equipped with heat shields. The electrical house includes a cooling unit, and cables are constructed from high-temperature resistant materials, effectively withstanding ambient thermal radiation exceeding 600°C.

Precision and High Efficiency: A Variable Frequency Drive (VFD) system provides hoisting speeds of 3–12 m/min and traversing speeds of 20–120 m/min, with a positioning accuracy of ±20 mm, perfectly suited for fast-paced steel-making processes.

Sturdy and Durable Structure: The four-girder, six-rail bridge design effectively distributes wheel loads. The trolley utilizes a double-layer structure for optimized force distribution. The main steel structure is verified through fatigue strength calculations, ensuring long-term, stable operation.

Intelligent Monitoring and Diagnosis: An integrated safety monitoring system continuously monitors lifting load, speed, temperature, and brake status in real-time. It features fault (early warning) and remote diagnostic capabilities, improving maintenance efficiency and equipment availability.

Remote Monitoring: Through IoT-based remote management, the system enables real-time awareness of the operational status of intelligent cranes. It continuously displays key parameters, wear conditions, and remaining service life of each mechanism. An authorized remote diagnostic system allows for fault diagnosis and preventive maintenance from any location, ensuring the crane remains in optimal working condition.
