Casting crane
Structural classification: Models below 125t typically adopt the YZ-type double-girder single-trolley structure, while models above 125t commonly use the YZS-type four-girder double-trolley (main/auxiliary trolley) structure.
Equipment Description
Structural classification: Models below 125t typically adopt the YZ-type double-girder single-trolley structure, while models above 125t commonly use the YZS-type four-girder double-trolley (main/auxiliary trolley) structure.
Core components: Composed of the bridge frame (box girder reinforced structure with a bottom heat-insulation layer to prevent high-temperature deformation; welds require ultrasonic testing (UT) and magnetic particle inspection (MT)), main/auxiliary trolleys (the main trolley transports molten steel ladles, while the auxiliary trolley can traverse under the main trolley for auxiliary tilting of steel ladles/slag or collaborative operations), lifting hooks, large trolley traveling mechanisms (often using quadrant drive, with 45° split forged wheels for superior load-bearing and maintenance), and electrical control systems.
Specialized design: Key components (main girders, trolley frames) are equipped with "rock wool board + high-temperature-resistant steel plate" insulation layers. The operator cabin and electrical room feature full thermal insulation and cooling equipment (e.g., industrial air conditioning). Transmission components use high-temperature-resistant lubricants (resistant to ≥200°C), and motors employ YZR/YZP series metallurgical cranes (class H insulation, IP54 protection). The hoisting mechanism incorporates redundant drives (e.g., dual-drive main hoisting for emergency operation at rated capacity if one set fails), with dual brakes on high-speed shafts and safety disc brakes on drums. It can also integrate specialized electronic scales, PLC control, and fault detection systems.
Application Fields
Product Advantages
The hoisting mechanism features "dual brakes + safety disc brakes + overspeed switches" for multi-layer protection, with redundant main hoisting drives (single set capable of emergency operation). It includes anti-sway stabilizers and tilt sensors for real-time ladle monitoring, as well as overload limits, zone load limits, and anti-collision stops (upper pre-limit, upper ultimate limit), fully complying with special equipment safety standards to ensure high-temperature molten metal handling safety.
High-temperature and wear-resistant, adaptable to harsh conditions
Key structures (main girders, trolley frames) feature thermal insulation, paired with high-temperature transmission components (steel-core wire ropes, class H insulation motors, high-temperature lubricants), enabling stable long-term operation in high-temperature, high-dust metallurgical environments. The main steel structure uses reinforced box girders, with forged wheels and hard-faced gear materials for wear resistance, significantly extending service life.
Intelligent and efficient, precise operation control
Equipped with variable frequency speed regulation, inch/micro/zero-speed suspension for smooth, precise hoisting and trolley control. Electronic anti-sway technology reduces load oscillation and improves positioning accuracy. Supports multi-hook coordination and multi-trolley synchronization for complex processes like "ladle tilting and large component precision lifting." Some models support wireless IoT integration for full lifecycle management and remote monitoring.
Customizable flexibility, meeting diverse needs
Configurable in structure (double/four girders, single/double trolleys), capacity (75t~320t+), and span (10m~40m). Optional features include "hook rotation, variable hook spacing" for specialized lifting processes in steelmaking, aerospace, and other fields.
