PRODUCT INTRODUCTION

The Four Beam Casting Overhead Crane is a specialized heavy-duty lifting solution purpose-built for steel mills, foundries, and metallurgical plants handling and transporting molten metal in extreme high-temperature environments. Built on a robust four-girder (double main beam + double auxiliary beam) structure with dual independent trolleys, the main trolley operates the primary hook for ladle lifting and pouring while the auxiliary trolley provides ladle tilting and auxiliary material handling. Designed for continuous operation with casting duty classes from A7 to A8, the crane is engineered to FEM, DIN, and CMAA standards for foundry service. The intelligent control system supports manual, semi-automatic, and fully automatic operation modes, ensuring safe operator positioning away from the high-temperature working zone during overhead molten metal transport. With capacities from 5 to over 320 tonnes, the crane delivers the reliability, thermal protection, and safety redundancy essential for critical steel mill casting operations.

Secondary metallurgy and ladle refining stations

Ferroalloy and non-ferrous metal smelting plants

FEATURES

Four-girder dual-trolley configuration — Two main girders and two auxiliary girders with independent main and auxiliary trolleys. The main trolley carries the primary hook for ladle lifting and pouring; the auxiliary trolley operates ladle tilting hooks and additional material handling tools, enabling independent or coordinated tandem operation across all lifting tasks.

Safe and reliable hot metal handling — The primary function is transporting and pouring molten metal using specially designed ladle hooks and lifting beams, with thermal radiation shielding to protect the main structural components during overhead ladle transfers.

Fail-safe safety redundancy — Multiple independent braking systems on each hoist, redundant power supplies, emergency lowering capability, and heat shields to protect critical components ensure safe operation under all conditions—with continuous cooling systems for motors and electrical enclosures when operating above ambient temperatures.

PLC-based intelligent control with VFD drive — Programmable logic controller manages all crane motions with variable frequency drive technology delivering stepless speed regulation, shock-free acceleration and deceleration, and precise positioning. The control system supports manual, semi-automatic, and fully automatic operation modes with real-time load monitoring and diagnostic fault logging.

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, and real-time diagnostics with fault alarm display — all monitored and logged by the PLC system.
