- Box girders
- Segments and assemblies
Why Double Girder Crab:
Capable of lifting very high loads with excellent structural stability.
8) PEB (Pre-Engineered Building) Industry
PEB units require cranes that can handle large built-up sections.
Applications:
- Rafters and built-up beams
- Heavy structural assemblies
Advantage:
Smooth operation across wide span sheds with minimal deflection.
9) Foundry & Casting Industry
Foundries require safe and shock-free lifting of heavy castings.
Used For:
- Large castings
- Molds and dies
- Furnace area material handling
Why Double Girder:
Superior control, stability, and safety in harsh environments.
10) Shipyard & Offshore Fabrication
Marine industries demand cranes with very high capacity and durability.
Applications:
- Ship blocks
- Heavy panels
- Offshore structures
Benefit:
Heavy-duty design suitable for extreme industrial conditions.
11) Tank, Vessel & Pressure Vessel Industry
Precision handling is critical for cylindrical and oversized loads.
Used For:
- Storage tanks
- Reactors
- Pressure vessels
Why Suitable:
Controlled lifting speed and accurate positioning.
12) Oil & Gas / Chemical Industry
Used in refineries, petrochemical plants, and chemical processing units. These cranes are used for lifting heavy reactors, storage tanks, and plant equipment. They are often designed with special safety features like flame-proof components to work in hazardous areas.
- Used in refineries and hazardous environments
- Handling heavy plant equipment and reactors
👉 Often designed with flame-proof features.
13) Aerospace & Defence Industry
Used in aircraft manufacturing and defence equipment production. These cranes provide precise lifting and positioning of aircraft parts, missile components, and large defence assemblies where accuracy and safety are critical.
- Handling aircraft components and large assemblies
👉 Used where precise heavy lifting is required.
14) Auxiliary Crab
An Auxiliary Crab is a smaller lifting unit mounted on a double girder EOT crane along with the main crab.
It is designed for lighter loads, faster operations, and precision handling where the main hoist is not required.
The auxiliary crab helps improve productivity, flexibility, and operational efficiency in industrial lifting operations.
Key Functions
- Handles smaller loads than the main hoist
- Used for precision positioning
- Supports maintenance and assembly work
- Allows simultaneous operations (main and auxiliary hoist)
- Reduces wear on the main hoist
Major Advantages
- Faster lifting speed than main hoist
- Ideal for repetitive light-duty operations
- Improves crane utilization
- Saves time and energy
- Reduces operational cost
15) Synchronized Double Girder Crab
A Synchronized Double Girder Crab is a heavy-duty lifting system mounted on a double girder EOT crane, designed to lift and move loads using two or more hoisting mechanisms working in perfect synchronization.
In this system, two hooks or hoists operate together, controlled electronically to lift long, heavy, or unbalanced loads safely and evenly.
Synchronization ensures equal load distribution, preventing tilting, twisting, or structural damage to the load.
Key Features
- Dual or multiple synchronized hoists
- Electronic load sharing system
- Equal speed and load distribution
- High precision lifting control
- Suitable for long or unbalanced loads
- Advanced safety interlocks
Main Functions
- Lifting long structures (beams, girders, pipes, etc.)
- Handling unbalanced or oversized loads
- Tandem lifting operations
- Precision positioning of heavy components
Advantages
- Prevents load tilting or twisting
- Ensures uniform load sharing
- Improves safety in heavy lifting
- Suitable for critical operations
- Reduces stress on crane structure
- Enables handling of extra-long components
Key Advantages of Choosing a Double Girder Crab
- Handles very heavy loads (10T – 300T+)
- Excellent stability and safety
- Higher lifting height & better hook approach
- Suitable for continuous & heavy-duty operation
- Long span capability
- Smooth, precise, and controlled lifting
- Long service life with low maintenance
- Designed as per IS standards
