PRODUCT INTRODUCTION

The QDY Model Heavy Duty Industrial Bridge Casting Crane is a specialized overhead lifting solution purpose-built for steel mills, foundries, and metallurgical plants that handle, transport, and pour molten metal in extreme high-temperature environments. Engineered with a four-girder four-rail structure and independent main and auxiliary trolleys, the main trolley carries the primary hook for lifting and pouring steel ladles, while the auxiliary trolley manages 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 components from radiant heat. The main structural steel is Q345B high-strength steel, with all main welds undergoing non-destructive testing to ensure a minimum 30-year service life. Rated for foundry duty classes A7–A8 with 24-hour continuous operation capability, the entire crane is designed in compliance with FEM, DIN, and CMAA standards for foundry service, and can be supplied with CE, ISO, and other international certifications.

FEATURES

Four-girder four-rail dual-trolley configuration — The main and auxiliary trolleys run on independent rail sets, distributing the load evenly across all four girders and providing exceptional stability under full-capacity hot metal loads. The main trolley handles steel ladle lifting and pouring; the auxiliary trolley manages ladle tilting and slag operations.

Safe and redundant hot 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 independently and safely lowers 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.

Fail-safe safety redundancy — Multiple independent braking systems on each hoist, redundant power supplies, emergency lowering capability, and heat shields protect critical components. The main hoist brake utilizes hydraulic-controlled block brakes mounted directly onto the drum for reliable braking performance under extreme conditions.

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 operate within safe temperature ranges during prolonged hot metal transfers.

Fully customizable configuration — Span, lifting height, main and auxiliary trolley capacities, ladle hook type, special spreader design, control mode (cabin, remote, or fully automated), and safety features are all customizable to specific steel mill layout, process requirements, and local compliance standards. Typical main/auxiliary capacities for QDY models range from 5/5t to 320/80t for four-girder configurations.
