Double Girder Crab Manufacturer In Ahmedabad
Double Girder Crab Manufacturer in India
Shakti Crane Industries is a premier manufacturer of precision-engineered Double Girder Crabs, designed for high-capacity lifting and smooth material handling. The “Crab” is the core lifting unit for Double Girder EOT and Goliath Cranes, housing the hoisting mechanism and cross-travel machinery. Our crabs are built for intensive duty cycles, with capacities ranging from 5 Tons to 100 Tons, ensuring maximum safety and operational efficiency.
As a leading Double Girder Crab Manufacturer & Exporter & supplier in Ahmedabad, Gujarat, we focus on robust construction and advanced engineering. Our crab units sit securely on top of the two main girders, providing superior hook height and stability compared to standard hoists. Whether for EOT cranes or Gantry cranes, Shakti Crane’s double girder crabs are the preferred choice for steel plants, heavy fabrication, and large-scale manufacturing units across India.
The Fundamentals of Double Girder Crabs (Crab Trolleys)
A Double Girder Crab, also known as a Crab Trolley, is the core hoisting and traversing unit designed specifically for double girder EOT and Goliath cranes. Unlike single girder hoists that hang from a beam, the crab sits securely on top of two parallel girders. This “top-running” design allows the hoist to achieve maximum hook height and provides superior stability for handling heavy-duty industrial loads with extreme precision.
The term “crab” refers to the compact, heavy-duty framework that houses the entire hoisting mechanism and the cross-travel machinery. Shakti Crane Industries offers high-performance crab configurations engineered to handle massive loads ranging from 5 Tons up to 100 Tons. Built for high-duty cycles (M5 to M8), our double girder crabs are the ideal choice for environments requiring continuous lifting, such as steel mills, heavy fabrication yards, and power plants.
As a trusted Double Girder Crab manufacturer and exporter in Ahmedabad, Gujarat, Shakti Crane Industries delivers robust lifting solutions configured to your specific operational needs. Our crabs are designed for structural integrity, smooth movement via VFD controls, and long-term reliability in the most demanding industrial settings.

Special Features of Double Girder Crabs (Crab Trolleys)
Engineered as the core lifting mechanism for heavy-duty cranes, our crab trolleys deliver unmatched strength, precision, and operational efficiency.
Heavy-Duty Lifting Power
Specifically engineered for high-capacity lifting, typically ranging from 5 Tons up to 100 Tons.
Maximizes Vertical Space
By sitting on top of the girders, the crab design offers superior lifting height compared to standard under-slung hoists.
Enhanced Structural Stability
The four-wheel top-running design ensures balanced weight distribution and stability during heavy lifts.
Customizable Attachments
Easily accommodates auxiliary hoists, specialized limit switches, and weight sensors for advanced operations.
Open-Frame Maintenance Access
Provides full walkways and platforms, allowing safe and easy servicing of motors, brakes, and gearboxes.
Applications of Double Girder Crabs
As the core lifting mechanism for heavy industrial cranes, our double girder crabs are widely used across demanding industrial environments.
Steel Melting Shops
Ideal for handling heavy ladles of molten metal, billets, and steel coils in high-temperature environments.
Power Generation Plants
Used for precise positioning and maintenance of turbines, generators, and heavy-duty transformers.
Heavy Engineering Units
Supports fabrication and movement of large-scale boilers, pressure vessels, and machine frames.
Shipbuilding Yards
Vital for lifting and assembling large hull sections and heavy marine engines with extreme precision.
Bulk Material Handling
Efficiently moves heavy machinery, oversized containers, and bulk cargo in wide-span yards and ports.
Industries We Serve
We manufacture heavy-duty Double Girder Crabs with lifting capacities ranging from 5 Tons to 100 Tons. These are designed for high-performance EOT and Goliath cranes used in intense industrial environments.
A Double Girder Crab sits on top of the girders (top-running), which provides maximum hook height and much better stability for heavy loads. It also allows for easier maintenance access compared to compact hoists.
Our crabs are engineered for high-duty cycles, supporting M3, M5, M7, and M8 classes as per IS:3177 standards. This makes them ideal for 24/7 operations in steel plants and heavy fabrication units.
Yes. We equip our crabs with Variable Frequency Drives (VFD) and high-precision gearboxes to allow for jerk-free movement and micro-speed lifting, which is essential for placing sensitive heavy machinery.
Every Shakti Crane Industries Double Girder Crab includes dual electromagnetic/hydraulic thruster brakes, over-hoist and over-travel limit switches, overload protection sensors, and emergency stop systems.
Absolutely. Our double girder crabs are designed with a spacious open-frame layout that easily accommodates an Auxiliary Hoist (e.g., a 10-ton aux hoist on a 50-ton main crab) for handling lighter loads quickly.
Our "Open Winch" design provides a maintenance platform and handrails on the crab itself. This allows technicians to easily inspect and service the motors, gearboxes, and rope drums without dismantling the unit.
