YZ200t Ladle Overhead Crane for High-Temperature Molten Metal Handling in Steelmaking Workshops

Customer Profile – MCC Oriental

MCC Oriental is a leading engineering and equipment supplier in the metallurgical sector, specializing in the construction and upgrading of large-scale steelmaking plants. The company provides integrated solutions covering steelmaking, continuous casting, rolling, and metallurgical logistics.

To enhance the efficiency and safety of molten metal transportation in its steelmaking workshop, MCC Oriental partnered with DAFANG CRANE to introduce an advanced heavy-duty ladle overhead crane system.

Project Overview – YZ200t Ladle Overhead Crane

To upgrade molten metal handling, MCC Oriental adopted the DAFANG YZ200t Ladle Overhead Crane, designed with a four-girder, four-rail twin-trolley structure.

Key specifications include:

• Span: 28 m
• Lifting Height: 22 m (main trolley) / 24 m (auxiliary trolley)
• Hydraulic Synchronous Hoisting System: 5 lifting points, synchronization error ≤0.1 mm
• Dual Operation Modes: Wireless remote control + cabin operation
• Standards Compliance: GB/T 3811 crane design code, ISO 12482 safety monitoring
• Environmental Adaptation: Optimized for high-temperature and heavy-dust metallurgical environments

This system enabled the customer to achieve breakthrough performance in molten metal transfer operations.

Core Application Scenarios

Hot Metal Ladle Transfer

• Task: Handling 180-ton hot metal ladles (Ø 3.5 m, H 4.5 m)
• Hydraulic synchronous hoisting + laser alignment
• Lifting time reduced from 2.5 hours to 55 minutes
• Verticality deviation controlled within 1/1000

Steel Billet Continuous Casting

• Task: Lifting 100-ton billets (14 m × 1.8 m) during continuous casting
• Four-girder design minimizes deflection
• Smooth operation with 35% reduction in scrap rate

Multi-Crane Coordinated Operation

• Task: Synchronous lifting of two continuous-casting billets (90 tons each)
• Precise synchronization of speed and position
• Operational efficiency +45%
• Energy consumption –28%

Key Technological Innovations

Hydraulic Synchronous Hoisting System

• Proportional valves + displacement sensors enable millimeter-level accuracy
• Equipped with emergency manual pump for safe lowering during power failure

Intelligent Safety Monitoring

• Real-time monitoring of 15 key parameters such as beam stress and support settlement
• 3D laser anti-collision system (70 m pre-warning range, ±8 cm accuracy)

Environmental-Resistant Design

• Q460E high-strength steel + dual thermal insulation layer
• Wind resistance up to Class 13
• Electrical system rated to IP67, suitable for extreme heat and dust

Customer Benefits & Feedback

Production Efficiency

• Steelmaking output increased from 1,400 tons/day to 1,900 tons/day
• Overall production rhythm improved by 35%

Cost Optimization

• Hydraulic synchronous system reduces energy use by 38%
• Annual electricity savings of approx. 2 million RMB

Safety Performance

• Zero accidents during six years of operation
• Certified by ISO 45001 Occupational Health & Safety

MCC Oriental recognizes this project as a benchmark for ultra-heavy-duty, high-temperature metallurgical crane applications, and a milestone in upgrading steel plant logistics toward efficient, safe, and green operations.
