How do you choose an EOT crane manufacturer in Rajasthan?
To choose an EOT crane manufacturer in Rajasthan, check five things: design to IS 3177 and IS 807, a duty class fixed from your real lifts per hour, a 125% load test at site, a full document set at handover, and local service support for AMC and spares. Ask every maker the same questions and compare written answers, not brochures.
A crane runs for many years. The wrong choice shows up as slow lifts, brake trouble, rope wear and long breakdowns. The right choice is quiet, safe and boring. This guide gives plant heads and purchase teams in Rajasthan a simple checklist to compare EOT crane makers on facts.
What should you check before you call any crane maker?
Write down your own data first. Makers can only give a correct design when the input is correct. Keep this sheet ready for every enquiry:
- Safe working load in ton, and any auxiliary hoist.
- Span (rail centre to rail centre) and lift height.
- Long travel length and the building or gantry it runs on.
- Lifts per hour and working hours per day.
- Shop conditions: heat, dust, outdoor use, hazardous area.
- Control: pendant, radio remote, two-speed or VFD.
Which standards prove an EOT crane is built right?
In India, three standards matter most. Ask that each one is named on the drawing and the test certificate.
| Standard | What it covers | What to ask the maker |
|---|---|---|
| IS 3177 | EOT and gantry cranes: classes, mechanisms, inspection and testing | Which duty class did you design to, and why? |
| IS 807 | Structural design, erection and testing of cranes | Share the girder calculation and deflection check |
| IS 3938 | Electric wire rope hoists: classes, rope safety factor, tests | What rope factor of safety and brake test did you use? |
For a deeper read, see our IS 3177 buyer guide and EOT crane duty class explained.
The 10-point manufacturer checklist
| # | Check | Good sign | Warning sign |
|---|---|---|---|
| 1 | Site survey | Engineer visits and measures before quoting | Quote sent from capacity and span only |
| 2 | Duty class | Class fixed from your lifts per hour | No class stated |
| 3 | Standards | IS 3177, IS 807, IS 3938 named | Only ‘as per IS’ with no number |
| 4 | Drawings | GA drawing and calculation shared for approval | Drawing only after order |
| 5 | Brakes and limits | Fail-to-safe brake, upper and lower limits, travel limits | Limits listed as optional |
| 6 | Load test | 125% static test at site with certificate | Test ‘if required’ |
| 7 | Documents | QAP, MTCs, rope and hook certificates, O&M manual | Only an invoice and warranty card |
| 8 | Certifications | Quality, environment and safety systems (ISO 9001, 14001, 45001) | No system certificates |
| 9 | Service reach | AMC and breakdown support within a few hours | No local team |
| 10 | Spares | Spares list at handover; parts planned ahead | Spares only on request |
Single girder or double girder – does the maker advise honestly?
A good maker will tell you when a single girder crane is enough and when you need a double girder crane for higher hook height, heavier loads or higher duty. Compare both in our guide single vs double girder EOT crane.
What does a 125% load test check?
At site, the crane is checked for deflection at rated load, run at rated load in all motions, and then holds 125% of its safe working load. Brakes, structure and hook are proved before your team uses it. Read what a 125% crane load test checks.
Common mistakes when buying an EOT crane
- Choosing on capacity alone and ignoring duty class – the hoist and brakes then wear out early.
- Skipping the site survey – rail level, building columns and headroom problems appear during erection.
- Not asking for wheel loads – the civil team cannot check the gantry girder or foundation.
- Accepting ‘load test if required’ – the 125% test should be part of every handover.
- Forgetting service – a crane without a planned AMC loses brake and rope condition fast.
Each of these mistakes costs more in downtime than it saves at purchase. A clear enquiry and the checklist above avoid all five.
Rajasthan plants: what changes by location?
| Area | Typical duty | Points to plan |
|---|---|---|
| Jaipur RIICO areas (VKI, Sitapura, Bagru) | Fabrication, engineering, warehouses | Low headroom hoists, VFD for fine placing |
| Bhiwadi, Neemrana | Auto parts, assembly lines | High lifts per hour, precise positioning |
| Kota, Chittorgarh | Cement, power and heavy industry | Higher duty class, dust-sealed motors and panels |
| Kishangarh, Rajsamand, Udaipur | Marble and granite yards | Gantry cranes, wind checks, outdoor paint |
| Jodhpur, Bikaner, Barmer | Hot and dusty sites | Panel cooling, IP-rated enclosures |

FAQs
Which standard should an EOT crane in India follow?
IS 3177 covers EOT and gantry cranes, and IS 807 covers structural design, erection and testing. Hoists follow IS 3938. Ask the maker to name these on the drawing and test certificate.
What load test should be done before handover?
A deflection check at rated load, a running test in all motions, and a static overload test at 125% of the safe working load, with a signed test certificate.
How do I know which duty class I need?
Count lifts per hour, hours per day and how heavy the usual load is compared with the rated load. The maker should fix the class from this data, not guess it from capacity alone.
Is a local manufacturer better than a distant one?
A maker within reach can do the site survey, erection, load test, AMC visits and breakdown support faster. Check how many hours it takes their engineer to reach your plant.
What documents should come with a new EOT crane?
GA drawing, design calculations, QAP, material test certificates, rope and hook certificates, load test certificate, O&M manual and a spares list.
राजस्थान में EOT क्रेन निर्माता कैसे चुनें?
देखें कि क्रेन IS 3177 और IS 807 के अनुसार डिज़ाइन हो, ड्यूटी क्लास आपके असली इस्तेमाल से तय हो, साइट पर 125% लोड टेस्ट हो, सभी ड्रॉइंग और सर्टिफिकेट मिलें, और AMC व स्पेयर सपोर्ट पास में उपलब्ध हो। आर के इंजीनियरिंग वर्क्स, वीकेआई एरिया, जयपुर, 1998 से यही प्रक्रिया अपनाता है।
