Double Girder Heavy Duty Ladle Crane

PRODUCT OVERVIEW

QDY Double Girder Crane for Metallurgy
The QDY double girder crane is made for lifting molten metal (like steel/iron) and hot materials. It lifts 5-100 tons, spans 10.5-31.5 meters, and works in high heat/dust (A7/M8 class). Compared to standard QD cranes, QDY has better heat protection, safety, and follows JB/T7688 standards.

Key Tests:

Safety Checks: Tested overload limiters, brakes, and emergency stops in heat to prevent accidents.
Dual-Hook Sync: Main/auxiliary hooks and motors work together for precise moves.
Smart Controls:

PLC + frequency control reduces sway for liquid metal.
Remote monitoring tracks data and faults.

Smooth Travel: Split-drive tech improves sync in heat/dust. Three-in-one drives (motor + brake + gear) cut failures by 30%.

In Steel Mills:

Used in casting/pouring zones with slag pot cranes.
Handles liquid steel/slag safely in high heat/humidity.
Double-girder design fits different loads and sizes.
Safety systems prevent operator errors.

Key Advantages of Double Girder Heavy Duty Ladle Crane

Strong Build for Harsh Conditions

Heavy-duty steel (Q235B/Q345B) for strength and long life.
Heat protection: Thermal baffles reduce steel radiation damage. Rock wool insulation and air coolers protect electric panels.

Accurate Movement & Safety

Four-corner drive keeps trolley stable with heavy loads.
Safety features: Overload protection, limit switches, emergency stop, and voltage protection.

Smart Weight Control

Electronic scale shows real-time weight in cab and on bridge.
Constant-spacing traverse secures ladle during steel handling.

High Productivity in Steel Mills

Main/auxiliary hooks work together for precise pouring.
Quality parts: F-class motors, vacuum-cast wheels, and ZPMC hooks.

Meets Industry Rules

Follows standards for steel plants and foundries.
Single-forming tech boosts strength.

Why Pick Our Ladle Crane?
✅ Handles heat and heavy loads – perfect for steel mills.
✅ Safety systems cut risks.
✅ Real-time tracking improves efficiency.

Emergency stop – Cuts power if overloaded or unsafe.

Replaces old cranes – Meets national safety rules for molten metal handling.

Double Girder Heavy Duty Ladle Crane – Where It Works

Our Double Girder Heavy Duty Ladle Crane handles high heat and heavy loads. It is used in:

1. Steel Mills & Foundries

Moves molten steel between furnaces, casting stations, and pouring lines.
Pours liquid metal into molds with the auxiliary hook.
Removes steel slag during refining.

2. Smelting Plants & Refineries

Transfers hot metal from blast furnaces to treatment areas.
Helps mix alloys with controlled pouring.

3. Heavy Casting & Forging Shops

Lifts large molds in foundries.
Moves hot billets between forging machines.

4. Power Plants & Heavy Factories

Handles boiler and turbine parts in power plants.
Installs furnace bricks during repairs.

5. Ports & Heavy Material Yards

Loads/unloads hot steel coils and ingots.
Transports slag and scrap metal.

Why It Works Best:
✔ Heat-resistant – Blocks molten steel heat with thermal baffles & insulation.
✔ Dual-hook system – Lifts and pours at the same time.
✔ Safe & precise – Electronic scales, limit switches, and overload protection prevent accidents.
