DOUBLE GIRDER OVERHEAD CRANE
Heavy-Duty Lifting Systems for Industrial Facilities
What is a Double Girder Overhead Crane?
A Double Girder Overhead Crane is an industrial lifting system designed to safely and efficiently lift, transport, and position heavy loads within manufacturing plants, warehouses, and industrial facilities. Built with two main bridge girders, this crane provides significantly higher load capacity, greater lifting height, and superior structural strength compared to single girder crane systems.
Double girder overhead cranes are widely used in steel fabrication plants, machine manufacturing facilities, energy plants, foundries, shipyards, and heavy industrial operations where reliability, durability, and high performance are essential.
How Does a Double Girder Overhead Crane Work?
A double girder overhead crane operates through three primary motions:
Bridge Travel Motion
The crane bridge moves forward and backward along runway rails installed on the building structure.
Trolley Travel Motion
The hoist trolley travels left and right across the bridge girders, allowing precise load positioning.
Hoisting Motion
The hoisting mechanism lifts and lowers the load using wire rope systems and heavy-duty motors.
These three coordinated movements enable safe and efficient material handling throughout the entire facility.
Advantages of Double Girder Overhead Cranes
Higher Lifting Capacity
Double girder crane systems are designed for heavy-duty applications and can handle significantly larger loads.
Common capacities include:
- 10 Ton Double Girder Overhead Crane
- 20 Ton Double Girder Overhead Crane
- 32 Ton Double Girder Overhead Crane
- 50 Ton Double Girder Overhead Crane
- 100 Ton Double Girder Overhead Crane
Greater Lifting Height
The hoist is mounted above the bridge girders, allowing maximum hook travel and increased lifting height compared to single girder systems.
This makes double girder cranes ideal for facilities with high ceilings and large-scale production operations.
Suitable for Heavy-Duty Operations
Double girder cranes are engineered to withstand:
- Continuous operation
- High-duty cycles
- Heavy industrial environments
- Large and complex loads
They are the preferred choice for demanding production facilities.
Wider Span Capabilities
Double girder overhead cranes can be designed for long spans exceeding 40 meters while maintaining structural stability and operational efficiency.
