PRODUCT INTRODUCTION

The YZ Type Four-Girder Double-Trolley Casting Overhead Crane is a specialized high-temperature resistant lifting solution purpose-built for steel mills, foundries, and metallurgical plants handling, transporting, and pouring molten metal ladles. Engineered with a four-girder four-rail structure and independent main and auxiliary trolleys, the main trolley (120t or 150t capacity) carries the primary hook for lifting and pouring steel ladles, while the auxiliary trolley (35t capacity) handles ladle tilting, slag pot operations, and auxiliary material handling-. All hoisting mechanisms are equipped with dual-drive and dual-braking redundant safety systems, with additional heat shields and thermal radiation protection panels installed to safeguard critical mechanical and electrical components from the extreme radiant heat of molten metal operations-. Constructed from Q345B high-strength structural steel and rated for foundry duty classes A7–A8 with continuous 24-hour operation capability, the entire crane is designed in compliance with FEM, DIN, and CMAA standards for foundry service, delivering the reliability and safety redundancy essential for critical steel mill casting operations-.

FEATURES

Four-girder four-rail dual-trolley configuration — The main and auxiliary trolleys run on independent rail sets, with the main trolley handling steel ladle lifting and pouring and the auxiliary trolley managing ladle tilting, slag operations, and auxiliary material handling. This structural arrangement distributes the load evenly across all four girders, providing exceptional stability under full-capacity hot metal loads.

Safe and redundant molten metal handling — The primary function is transporting and pouring molten steel using ladle hooks and lifting beams. Every hoisting mechanism features dual-drive and dual-braking redundancy: if one drive or brake fails, the other can independently and safely lower the ladle to the ground. All hoist drums, wire ropes, and hook assemblies are rated for high-temperature service with metal-core high-temperature-resistant wire ropes.

Thermal radiation protection — Heat shields and radiation protection panels are installed between the main girder and the trolley to absorb radiant heat from the molten metal ladle, ensuring electrical enclosures, VFD drives, and PLC control cabinets remain within safe operating temperatures during prolonged hot metal transfers.

PLC-based intelligent control with VFD drive — A programmable logic controller manages all crane motions with variable frequency drive technology delivering stepless speed regulation, shock-free acceleration and deceleration, and precise load positioning. The control system supports multiple operation modes with real-time load monitoring, diagnostic fault logging, and optional automated ladle handling cycles.

Comprehensive safety protection — Integrated safety systems include dual overload protection, upper and lower limit switches, emergency stop, phase sequence and voltage protection, anti-collision sensors, zero-position protection, and real-time diagnostics with fault alarm display — all monitored and logged by the PLC system-.
