Four Girder Ladle Crane, Ultra-Heavy Duty Overhead Crane for Steel Mill

PRODUCT OVERVIEW

Four Girder Ladle Crane – Key Advantages & Outstanding Features

1. Robust & High-Performance Design

Four-Girder & Four-Rail Structure – Ensures superior load-bearing capacity and stability for heavy-duty molten metal handling.
Dual Crab System (Main + Auxiliary) – The main crab (with connecting traverse) handles ladle lifting, while the auxiliary crab (with hook) assists in pouring molten steel and slag.
Four-Corner Drive Mechanism – Enhances smooth trolley travel and reduces wheel slippage.

2. Advanced Heat & Stress Resistance

Thermal Baffle & Insulation – A heat-resistant baffle along the girder minimizes thermal radiation damage.
Rock Wool Insulation & Air Cooling – Electric panel rooms are heat-insulated and equipped with air coolers for prolonged component life.
Two-Stage Welding & Assembly – Primary assembly fixes dimensions via flat welding, while secondary assembly relieves stress for precision, ensuring long-term structural integrity.

3. Precision & Safety for Molten Metal Handling

Special Electronic Scale & Real-Time Monitoring – Weight display in both cabin and bridge for accurate load tracking.
Dual-Wire Rope Safety – Each pulley has two wire ropes for redundancy, preventing accidents if one fails.
Multiple Braking Systems – 4 brakes for main lift + 2 per lifting point + overspeed switch for fail-safe operation.
Anti-Collision & Limit Switches – Wireless anti-collision devices and dual travel limit switches (preliminary + final).

4. Customizable & Adaptable to Harsh Conditions

Flexible Speed Control – Adjustable lifting/travel speeds based on customer requirements.
Wide Temperature Range – Operational from -10°C to +60°C (suitable for foundries and steel plants).
Multiple Power Options – Standard 3-phase, 380V, 50Hz or customized voltage/frequency.

5. Enhanced Electrical & Safety Protections

Overload Protection – Auto-shutdown (only allows lowering motion when overloaded).
Anti-Falling Mechanism – Secures the Three-in-One electric motor against accidental drops.
Safety Hook Latch – Prevents load slippage during lifting.
Comprehensive Electrical Safeguards –

Overcurrent, short-circuit, and phase-sequence protection
IP54/IP55 protection against dust/water ingress
Zero-position, voltage-loss, and emergency stop systems

6. Ideal for Extreme Industrial Applications

High Capacity (125/32T+) – Handles ultra-heavy ladles with stability.
A7 Work Class – Built for intensive, continuous foundry operations.
Optimized Ladle Control – Dual-crab system allows precise molten steel pouring and auxiliary tasks.

APPLICATION SCENARIO

Application Scenarios of Four Girder Ladle Cranes

Four Girder Ladle Cranes are essential heavy-duty lifting solutions designed for high-temperature, high-risk molten metal handling in demanding industrial environments. Below are the key applications:

1. Steel Mills & Metallurgical Plants

Ladle Transport & Pouring – Safely moves molten steel ladles between furnaces, casting stations, and refining areas.
Continuous Casting Lines – Supports precise pouring into continuous casting machines (CCM) for slab, bloom, or billet production.
Electric Arc Furnace (EAF) & Ladle Furnace (LF) Operations – Handles hot metal charging and slag removal during steelmaking.

2. Foundries & Metal Casting Facilities

Pouring Molten Metal into Molds – The auxiliary crab enables controlled pouring into sand molds, die-casting machines, or ingot molds.
Ladle Maintenance & Relining – Assists in positioning ladles for refractory lining repairs.
Scrap Charging – Loads scrap metal into furnaces for melting.

3. Smelting & Refining Workshops

Copper, Aluminum & Non-Ferrous Metal Processing – Transfers molten non-ferrous metals in refineries and smelters.
Slag Handling – Removes and disposes of slag waste from furnaces.

4. Heavy Industrial Manufacturing

Forging & Heavy Press Shops – Positions large, heated metal billets for forging presses.
Heat Treatment Facilities – Moves high-temperature workpieces in and out of quenching tanks or annealing furnaces.

5. Specialized High-Temperature Applications

Nuclear & Power Plant Component Fabrication – Handles radioactive or high-precision castings in controlled environments.
Aerospace & Defense Metalworking – Supports titanium/aluminum alloy casting for critical components.

Why This Crane Excels in These Scenarios?
