Bridge Crane: Your Reliable Partner for Heavy Lifting

A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machinery.

Overhead Bridge Cranes are defined by critical performance metrics:

• Lifting Capacity: Ranges from 1 ton to 500 tons for diverse needs.
• Span: Customizable from 5m to 35m to fit workspace layouts.
• Lifting Height: Standard options cover 6m to 30m for multi-level facilities.
• Duty Class: Ranges from A3 to A7 for varying operational intensity.
• Speed Control: Equipped with variable frequency drives (VFD) for precision.

Key Components:

1. Main Girder: Box-type or truss structure for load bearing.
2. End Carriages: Connect girders to rails for lateral movement.
3. Hoisting Mechanism: Motors, wire ropes, and hooks for vertical lifting.
4. Electrical System: PLC controls + wireless remote for safety and flexibility.

Typical Use Cases:

• Manufacturing: Engine lifting in automotive plants, steel coil handling.
• Energy Sector: Turbine installation in hydropower stations, wind turbine assembly.
• Logistics: Container loading at ports, warehouse material handling.
• Aerospace: Precision assembly of aircraft components.

Installation Guidelines:

1. Rail Alignment: Horizontal tolerance ≤2mm/10m.
2. Structural Assembly: High-strength bolting to prevent welding distortion.
3. Electrical Testing: Verify limit switches and overload protection.

Maintenance Tips:

• Daily Checks: Inspect wire ropes and brake responsiveness.
• Lubrication: Apply lithium grease to gears and bearings monthly.
• System Updates: Upgrade PLC software biennially.

Competitive Advantages:

• Efficiency: Full 3D coverage minimizes dead zones.
• Safety: Dual brakes + anti-sway tech reduce accidents by 90%.
• Cost-Effectiveness: Modular design extends service life to 30 years.
