Overview
The double girder EOT crane uses two torsion-free box girders instead of one, giving it the structural stiffness to lift heavier loads over longer spans than a single girder crane allows. AMBAT ICONCRANES builds double girder cranes for 10 tonnes and above - up to 150 tonnes SWL - for spans exceeding 25 metres, with the hoist trolley running on top of the girders for better hook approach and higher hook height within the same building clearance.
Key Features
- Two torsion-free welded box girders for higher structural stiffness
- Top-running hoist trolley for improved hook height and approach
- Class II duty standard, Class IV continuous duty available
- Central drive option; standard dimension tables based on 10 M lift height
- Engineered for steel plant, foundry and heavy fabrication duty cycles
Benefits
- Higher capacity and longer span than single girder cranes within the same building envelope
- Better hook approach reduces dead zones at the ends of the runway
- Class IV construction available for near-continuous steel plant and grabbing crane operation
- Pairs directly with AMBAT ICONCRANES' steel plant equipment line (ladles, C-hooks, coil tilters) as one engineered system

Why Choose Our Product
- Engineered for the specific capacity, span and duty cycle of your plant, not a fixed catalogue size
- Pairs seamlessly with our steel plant equipment (ladles, C-hooks, coil tilters) as one coordinated system
- Class IV continuous duty available where the plant genuinely runs near-continuous shifts, avoiding under-specification risk
Manufacturing & Quality Process
Standard dimension tables assume a 10 metre lift height; specifications above 25 tonnes are engineered against specific enquiry, since girder depth, wheel base and drive configuration all shift with capacity and span. Central drive is available on request, and Class IV duty construction can be supplied for continuous or heavy-shock loading applications.
Product Comparison
| Feature | Double Girder EOT | Goliath EOT |
|---|---|---|
| Support Structure | Building-mounted runway beams | Freestanding legs on wheels/rail |
| Best For | Indoor heavy lifting, long spans | Outdoor/no-runway sites |
| Capacity Range | 10 - 150 Ton | Custom, outdoor rated |
| Civil Cost | Higher (runway structure needed | Lower (no permanent runway needed) |
Certifications & Compliance
- Class II duty per IS 807 (1963) & IS 3177 (1977, Revised) as standard
- Class IV continuous duty available on request
- AISE, DIN, JIS, FEM references applied for export builds
Installation & Maintenance
Installation covers girder erection, runway alignment, drive and electrical commissioning, with load testing at the specified SWL. Given the heavier duty class typical of double girder applications, AMC packages for this crane type typically include more frequent wire rope and brake inspection intervals than single girder AMC - discuss inspection frequency against your actual duty cycle when setting up a contract.
Accessories & Compatible Products
- Top-running hoist trolley (single or twin)
- Control panel / VFD (see Automation Solutions)
- Grab bucket attachment (see Other Products)
- Ladle and coil handling attachments
Frequently Asked Questions
Q1. What's the maximum capacity for a double girder EOT crane?
Up to 150 tonnes SWL for spans exceeding 25 metres, engineered against specific enquiry above 25 Ton.
Q2. Why choose double girder over single girder for a 15 Ton load?
If span, hook height or duty cycle push beyond single girder limits, double girder's top-running trolley gives better hook approach and can be built to Class IV for continuous operation.
Q3. Can this crane be fitted with a grab bucket instead of a hook?
Yes, double girder cranes are commonly paired with grab buckets for bulk material handling - see the Grab Bucket & Steel Plant Equipment page
Q4. What lift height do the standard dimensions assume?
10 metres; other lift heights are engineered against the specific enquiry.
Q5. Is Class IV duty available for continuous steel plant operation?
Yes, Class IV continuous duty construction is available on request.
