Core Working Application & Matching Attachments

This overhead crane is exclusively applied to the converter charging cross operation area in iron and steel smelting enterprises, covering the whole process from scrap yard material transfer to converter furnace feeding. It can be equipped with two mainstream working attachments according to actual production demands to adapt to different scrap steel handling scenarios:

250 Ton Scrap Charging Overhead Crane

• ◆ Electromagnetic Chuck: Suitable for grabbing bulk, fragmented and thin-plate scrap steel. It features strong magnetic adsorption force, wide material coverage and fast loading speed, which is ideal for rapid bulk feeding of conventional scrap steel materials.
• ◆ Mechanical Scrap Grab: Adopts durable clamping structure, applicable for handling large-size, heavy and irregular scrap steel and steel block materials. It has stable clamping force and anti-shedding performance, avoiding material leakage during high-altitude transportation.

With dual-attachment switching capability, the crane can independently complete full-process operations including scrap steel loading from the stockyard, precise transportation of scrap buckets, accurate positioning above the converter and automatic tipping feeding, perfectly matching the continuous and high-efficiency production rhythm of modern steelmaking lines.

Structureel ontwerp & Technische voordelen

Adopting heavy-duty double-girder bridge structure and A7/A8 high working grade design, the crane fully meets the long-term continuous heavy-load operation requirements of metallurgical workshops. The main beam is made of high-strength low-alloy steel, which undergoes integral welding, stress relief annealing and precision machining, featuring high rigidity, strong bearing capacity and small deformation, ensuring stable operation under 250-ton rated load for a long time.

The lifting mechanism adopts a dual-hoist redundant design with independent main and auxiliary lifting systems. The main hook undertakes heavy-load lifting of scrap steel buckets, while the auxiliary hook assists in bucket tilting, fine positioning and residual material cleaning, realizing collaborative operation and improving feeding accuracy. All walking and lifting mechanisms are equipped with frequency conversion speed regulation systems, waardoor een soepele start mogelijk is, stop and stepless speed adjustment, effectively preventing load sway and ensuring precise positioning during converter charging.

In view of the harsh metallurgical working environment, the whole machine is designed with high temperature resistance, dust resistance and corrosion resistance. Belangrijke componenten zoals motoren, reducers and electrical control cabinets adopt industrial high-temperature resistant models, with sealed and dust-proof structures to adapt to high-temperature radiation and dust-filled workshop environments, reducing equipment failure rate and extending service life.

Uitgebreid veiligheidsbeschermingssysteem

As key high-risk equipment for steelmaking production, this 250-ton scrap charging overhead crane is equipped with full redundant safety protection devices to ensure zero-risk operation in heavy-load and high-temperature scenarios:

• ◆ Dual Brake System: The main lifting mechanism is equipped with dual independent brakes with backup protection function, which can reliably lock the load in case of single brake failure to prevent accidental falling of heavy objects.
• ◆ Multi-layer Limit Protection: Uitgerust met hefhoogtebegrenzing, travel limit and overload limit devices. It will automatically cut off the power and alarm in case of over-lifting, over-running or overloading to avoid equipment collision and overload damage.
• ◆ Real-time Monitoring System: Equipped with intelligent operation monitoring module, which real-timely displays operating parameters such as load weight, hefhoogte, operating speed and equipment status, and records operation data for traceability and predictive maintenance.
• ◆ Anti-sway & Emergency Protection: Built-in intelligent anti-sway algorithm suppresses load swing during operation; equipped with emergency stop button and power-off protection device to respond to sudden faults quickly and ensure personnel and equipment safety.
