Product Description

The Electric Four-Girder Heavy-Duty Bridge Foundry Crane is engineered for extreme industrial environments where ultra-heavy lifting, extreme heat, and corrosive conditions demand unparalleled structural integrity. Featuring four primary girders arranged in a box-type configuration, this crane delivers superior rigidity and load distribution, eliminating deflection even at maximum capacity (typically 50-800+ tons).

Application Scenarios

Steel Foundries & Smelters:
Transporting ladles with molten metal (up to 1600°C)
Handling slag pots (20-100-ton capacity)
Moving casting molds under thermal shock conditions

Heavy Forging Shops:
Lifting 400-ton ingots for hydraulic presses
Positioning oversized die blocks

Nuclear/Power Component Fabrication:
Rotor assembly for turbines (>600-ton loads)
Reactor pressure vessel installation

Shipyard Dry Docks:
Launching sections of aircraft carriers and LNG tankers

Our Advantages

1. Unmatched Structural Stability
Quad-girder design reduces beam stress by 60% vs. double-girder cranes, enabling 1.5x higher safety factors 
Zero deflection at 125% test load ensures precision during molten metal transfer.

2. Extreme Environment Resilience
Triple-layer thermal protection:
Ceramic-coated wire ropes
Water-cooled hook blocks
Stainless steel 316L electrical enclosures
IP66-rated components withstand metal dust, humidity, and chemical vapors.

3. Fail-Safe Operations
Quad-redundant safety systems:
Primary/secondary hydraulic brakes
Emergency grounding for ladle currents
Infrared load temperature monitoring (shuts down at >1000°C threshold)
Seismic dampers for earthquake zones (IBC 2018 compliant)

4. Smart Productivity Features
Predictive maintenance AI: Vibration sensors forecast bearing failures 500+ hours in advance.
Automated path optimization: Reduces cycle times by 30% in congested foundry layouts.
Wireless hot-metal remote control with 500m range (prevents operator exposure).

5. Lifetime Cost Efficiency
50-year fatigue life (per ISO 12488-1) with modular rebuildable components.
Regenerative power drives capture braking energy (up to 35% electricity savings).
 

Packaging & Shipping

To ensure safe and damage-free transportation, cranes must be securely packaged in heavy-duty wooden crates or steel frames, with critical components like hoists and girders disassembled if oversized and properly strapped. Electrical systems and sensitive parts should be wrapped in waterproof, anti-corrosion materials, while all packages must be clearly labeled with weight, center of gravity, and lifting points. During transit, components must be firmly fastened using chains or straps to prevent shifting, with special attention given to corrosion protection for sea freight and route planning for oversized shipments. These measures guarantee that cranes arrive in optimal condition for assembly and operation.
