Double Girder Goliath Crane Manufacturers & Suppliers in India — Ganesh Engineering Co.
Ganesh Engineering Co. manufactures Double Girder Goliath Cranes for heavy-duty lifting in open areas and outdoor work sites. These cranes are perfect for industries that need strong, dependable material handling and a fixed overhead crane is not practical or achievable. Designed for easy movement, safe lifting and long term use.
What is a Double Girder Goliath Crane?
It is a heavy-duty, self-supporting crane built on two parallel bridge girders mounted on two A-frame legs that travel on ground-level rails. Unlike overhead cranes that rely on a building’s runway structure, a goliath crane stands completely on its own.
The crab trolley mechanism sits on top of the two bridge girders and travels between them. This gives the crane higher hook height, greater lifting capacity, and more structural rigidity than a single girder design — making it the standard choice for the heaviest outdoor lifting applications.
It handles loads in three directions — vertically via the hoist, laterally via the crab cross travel, and longitudinally via the gantry long travel along the ground rails — covering the full working area with precision.
It is also known as a Double Girder Gantry Crane, Double Beam Goliath Crane, Heavy Duty Gantry Crane, or Portal Crane in different parts of the industry.
How Does a Double Girder Goliath Crane Work?
The crane operates on three basic motions that together give it complete coverage of the working area:
The crab hoist raises and lowers the load vertically with fail-safe braking on the hoist motor — the load stays exactly in place even if power is cut.
Crab Cross Travel — Lateral Movement
The crab trolley moves left and right on rails mounted on top of the two bridge girders, covering the full working span width.
Gantry Long Travel — Longitudinal Motion
The entire gantry structure travels forward and backward along the ground-level runway rails, covering the full length of the working area.

Why Choose Us as Your Double Girder
Goliath Crane Manufacturer?
Outdoor Application Expertise
Goliath cranes work in conditions that overhead cranes never face — wind, rain, temperature variation, and heavy yard environments. We have been designing cranes specifically for these conditions since 2004. That site-level experience shows in how our cranes are built and how long they last.
Every Crane Tested to 125% SWL
Before any crane leaves our facility, it is load-tested to 125% of its Safe Working Load as per IS:807 and IS:3177. What you receive on site is a verified, tested crane — not just a manufactured one.
Custom Engineering From Day One
Yard layout, ground conditions, span, capacity, hook height, duty cycle, outdoor exposure — all of it goes into the design. We do not adapt a standard crane to fit your site. We engineer a crane around it.
In-House Gearbox Manufacturing
Our gearboxes are manufactured in-house at our Ahmedabad facility. Spare parts are available from our own stock — not subject to third-party lead times. For a crane that is working in a remote yard or on a critical project, that availability makes a real difference.
Delivery and Commissioning Support
We handle installation and commissioning wherever the crane is being set up — whether in Gujarat, another Indian state, or an export destination. The crane is handed over fully operational and tested on-site.
One Year Warranty and Ongoing Support
Every crane comes with a one-year warranty, free quick-wear parts during the warranty period, and dedicated engineer support at any time after that. Annual maintenance contracts are available for facilities that want scheduled servicing.
Frequently Asked Questions
What is a Double Girder Goliath Crane?
A Double Beam Goliath Crane is a self-supporting heavy-duty crane built on two parallel bridge girders mounted on A-frame legs that travel on ground-level rails. It requires no building runway structure and is designed for heavy outdoor lifting applications — from steel yards and construction sites to shipyards and power plants.
What is the difference between a Goliath Crane and a Gantry Crane?
The terms are used interchangeably in the industry. Both refer to self-supporting cranes that run on ground-level rails. In India, the term "Goliath Crane" is commonly used for larger, heavier outdoor cranes, while "Gantry Crane" is used more broadly. Both designs work on the same principle.
What is the maximum capacity of a Double Girder Goliath Crane?
We manufacture Double Beam Goliath Cranes of up to 100 tons capacity with spans up to 50 metres. For higher requirements, please contact us for a custom engineering assessment.
Why is a Double Girder Gantry Crane better than a Single Girder for heavy loads?
Two girders provide greater structural rigidity and allow much higher hook heights because the crab trolley sits on top of the girders rather than hanging below. This makes the double girder design the right choice for loads above 20 tons and high-frequency, heavy duty applications.
Can a Double Girder Goliath Crane work outdoors?
Yes — outdoor use is one of the main reasons these cranes are chosen. They are built with weatherproof components, appropriate coating, and IP-rated electrical equipment for outdoor environments. Coastal and chemical environment configurations are also available
Can the crane travel length be extended in future?
Yes. Because the crane runs on ground-level rails, extending the long travel length is relatively straightforward and significantly less expensive than extending an overhead runway structure.
What IS standards apply to Double Girder Goliath Cranes?
All our cranes are designed and manufactured as per IS:807 and IS:3177, and tested to 125% of SWL before dispatch.
Do you provide installation and maintenance for Goliath Cranes?
Yes — we provide complete installation and commissioning support, annual maintenance contracts, breakdown assistance, and spare parts from stock for all cranes we supply across India and for export customers.
What industries use Double Girder Goliath Cranes?
Steel plants, shipyards, power plants, heavy fabrication yards, construction sites, railway workshops, defence facilities, and any industrial environment where heavy loads need to be moved in open or semi-covered areas.
