PRODUCT INTRODUCTION

The Foundry Ladle Overhead Crane, commonly referred to in the industry as the ladle crane or molten metal handling crane, is a purpose-built heavy-duty lifting solution engineered exclusively for the steelmaking, iron casting, and non-ferrous metal smelting industries. Unlike general-purpose overhead cranes, this equipment is specifically designed to lift, transport, and pour ladles filled with liquid metal at temperatures exceeding 1,500°C. It represents the highest safety classification among all overhead crane types—every component is engineered for continuous, reliable operation in extreme heat, heavy dust, and hazardous environments where equipment failure is not an option.

TECHNICAL DATA

APPLICATION

Integrated steel mills and steelmaking plants

Foundries, iron casting, and forging facilities

Converter charging bays, refining bays, and continuous casting turntable stations

Electric arc furnace (EAF) and blast furnace (BF) workshops

Secondary metallurgy, ladle refining, and slag handling stations

Ferroalloy and non-ferrous metal smelting plants

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-.
