How does the switching mechanism work between the grab and magnet on a dual-purpose double beam overhead crane?

Our double beam overhead crane with grab and magnet offers quick and versatile attachment switching depending on your operational setup: Quick-Release Mechanical & Electrical Connections: Enables operators to swap between the electro-hydraulic grab and the lifting magnet in under 15–20 minutes. Dual-Hoist / Rotating Trolley System: Optional configurations feature a double-trolley or specialized spreader beam (carrier beam) that holds both the magnet and grab simultaneously, allowing the operator to switch modes instantly via a selector switch in the cab or remote controller.

What safety systems protect against magnet power loss and accidental dropping of metal scrap?

Safety is paramount when handling heavy steel scrap or pig iron. Yuntian magnet overhead bridge cranes are equipped with an advanced Backup Battery Magnet Retention System (UPS): Instant Battery Backup: In the event of a main power failure, the system automatically switches to battery power within milliseconds, maintaining full magnetic holding force for at least 20 to 30 minutes. Audio-Visual Alarms: Triggers immediate optical and acoustic warning signals, giving personnel ample time to clear the area and allowing the operator to safely lower the suspended load.

What types of grabs are recommended for scrapyard and bulk material handling?

The choice of grab depends entirely on the bulk density and shape of the materials handled by the double girder grab crane: Orange Peel (Multi-Peel) Grab: Best for irregular bulky materials like heavy scrap steel, crushed car bodies, and pig iron chunks. Clamshell Grab: Ideal for granular or powdery bulk materials such as coal, ore powder, sand, slag, and limestone. Motor-Hydraulic vs. Mechanical: We provide both self-contained electro-hydraulic grabs and four-rope mechanical grabs driven directly by the crane winches.

How is the crane engineered to endure high-temperature and heavy-dust metallurgical environments?

Built for extreme duty cycles (ISO A6 to A8 / FEM 3m to 5m), our dual-purpose double beam EOT cranes incorporate heavy-duty metallurgical protection: Heat Insulation & Sealed Cab: Main girders and electrical panels feature thermal shielding; operator cabs are fully enclosed, air-conditioned, and insulated against radiant heat. VFD & Heavy-Duty Motors: Class F/H insulated motors equipped with Variable Frequency Drives (VFD) for smooth acceleration, reducing mechanical shock and cable wear during 24/7 continuous duty.

PRODUCT INTRODUCTION

The QP Double Beam Overhead Crane with Grab and Magnet is a heavy-duty dual-purpose lifting solution designed for handling both bulk materials and ferrous metal products. Equipped with interchangeable grab buckets and electromagnetic lifting devices, the crane provides exceptional versatility for facilities that need to transport loose materials as well as steel scrap, billets, plates, and other magnetic loads.Built with a robust double-girder bridge structure and A6 heavy-duty classification, the QP crane delivers reliable performance under demanding operating conditions. Users can switch between grab operation and magnetic lifting depending on production requirements, eliminating the need for multiple specialized cranes and improving equipment utilization.This crane is widely used in steel mills, power plants, recycling facilities, warehouses, and material stockyards where both bulk material handling and magnetic lifting are required.
