R K ENGINEERING WORKS designs, builds and installs custom-engineered EOT cranes in Jaipur for plants across Rajasthan and North India. Every crane is designed to IS 3177 and IS 807, built for the duty class of your process, and load-tested at 125% of safe working load before handover. Since 1998, we have supplied cranes and lifts to manufacturing plants, warehouses and public-sector sites. ISO 9001, ISO 14001 and ISO 45001 certified.

What you get with an RKEW EOT crane
- Designed for your duty, not picked from a catalogue. We size girders, end carriages, hoist and drives from your load, span, lift height and hours of use.
- Designed to Indian Standards. IS 3177:2020 for the crane and mechanisms, IS 807 for the steel structure, IS 3938 for electric wire rope hoists.
- Load-tested at 125%. Static overload test at 125% of safe working load, plus full-load running tests of every motion, at your site, with a signed test certificate.
- Complete documents. GA drawing, design calculations, QAP, material test certificates, load test certificate, operation and maintenance manual.
- Safety first. Overload protection, upper and lower limit switches, travel limit switches, emergency stop and safe electrical panel design.
- Lifetime support. AMC, spare parts, inspection and modernisation from our works in VKI Area, Jaipur.
Types of EOT cranes we build
| Crane type | Right choice when | Typical use |
|---|---|---|
| Single girder EOT crane | Light to medium loads, medium spans, limited headroom | Assembly bays, fabrication shops, warehouses, maintenance bays |
| Double girder EOT crane | Heavier loads, longer spans, higher hook height, higher duty class | Steel, cement, power plants, heavy engineering, process plants |
| Underslung (under-running) crane | The crane must hang from the roof structure | Clean production halls, pharma and FMCG lines |
| Gantry and semi-gantry crane | Outdoor yards or bays without a crane gantry girder | Stockyards, precast yards, loading bays |
| Goliath crane | Large outdoor spans and heavy loads | Steel yards, infrastructure, fabrication yards |

How to choose the right duty class
Duty class decides how long your crane will last and how often it will stop for repair. IS 3177:2020 groups crane mechanisms from M1 (very light use) to M8 (very heavy, continuous use). A crane built for the wrong class wears out early, even if the capacity is right. Read our full duty class guide.
| Mechanism class | How the crane is used | Example plants |
|---|---|---|
| M3 – M4 | Occasional lifts, often below full load | Maintenance bays, power house cranes, stores |
| M5 | Regular daily production use, mixed loads | General engineering, automobile parts, warehouses |
| M6 | Frequent lifts, many hours a day, often near full load | Fabrication, cement, process plants, busy dispatch bays |
| M7 – M8 | Heavy, near-continuous duty | Steel melt shops, rolling mills, heavy process lines |
Our engineers fix the class from your real data: lifts per hour, hours per day, and how heavy the usual load is compared to the rated load. We write the class on the GA drawing so your auditor and insurer can see it.
What we need from you to design your crane
| Input | Why it matters |
|---|---|
| Safe working load (ton) and any auxiliary hoist | Sizes hoist, rope, hook and girders |
| Span (rail centre to rail centre) | Decides single or double girder and girder depth |
| Height of lift and building clear height | Decides hoist type and crab layout |
| Long travel length | Sizes conductor system and cable |
| Duty: lifts per hour, hours per day | Sets mechanism class and motor rating |
| Speeds, and need for VFD smooth control | Sets drives, panel and positioning accuracy |
| Site conditions: indoor/outdoor, dust, heat, flammable area | Sets IP rating, paint and electrical design |
| Existing gantry girder and rail details | Checks that the building can take the crane loads |
Not sure about some values? Our engineer will measure them during the site survey.
Our process: design, build, test, support
- Site survey – our engineer measures span, rails, clear height and power supply at your plant.
- Design and drawings – GA drawing and design calculations to IS 3177 and IS 807, shared for your approval.
- QAP – quality plan with inspection stages; your team or a third-party inspector can witness.
- Fabrication at our Jaipur works – girder welding, end carriages, crab, hoist assembly, painting.
- Factory testing – hoist and panel tests before dispatch.
- Erection and commissioning – by our own trained crew, with safety procedures and PPE.
- Load test at site – static test at 125% of safe working load and full-load running test of all motions; see how the load test works.
- Training and handover – operator and maintenance training, O&M manual, spares list.
- Lifetime support – AMC, periodic inspection, spares and upgrades.
Safety and control features
- Overload protection on the hoist
- Hoist upper and lower limit switches; travel limit switches with end buffers
- Emergency stop and main isolator; motor overload and phase protection in the panel
- VFD drives for smooth start and stop and accurate positioning (on request)
- Pendant, radio remote or cabin control
- Warning horn and lights; anti-collision for two cranes on one gantry (on request)
Industries we serve
Steel and metal processing, cement, power plants and substations, automobile and auto parts, pharma, FMCG, warehousing and logistics, engineering and fabrication, public-sector units and Railways workshops.
Where we work
From our works at VKI Area, Jaipur, we serve Sitapura, Bagru, Kaladera and all RIICO areas in and around Jaipur, plus Bhiwadi, Neemrana, Alwar, Kota, Ajmer, Bhilwara, Jodhpur, Udaipur, Sikar and Bikaner. We also take projects across North India and pan-India.
Already have a crane? We also upgrade old cranes
Old crane stopping often, or failing an audit? We inspect, repair and modernise existing EOT cranes: new hoists, VFD panels, radio remote, limit switches, conductor systems and a new load test with certificate. Ask for a crane health check.
Frequently asked questions
Which Indian Standard applies to EOT cranes?
IS 3177:2020 covers electric overhead travelling and gantry cranes for all applications. IS 807 covers design, erection and testing of the crane structure. Electric wire rope hoists follow IS 3938. RKEW designs every EOT crane to these standards.
What is the load test for a new EOT crane?
Before handover, the crane must lift and hold a test load of 125% of its safe working load, and all motions are run at full load. RKEW does this test at your site and gives a signed test certificate.
Single girder or double girder – which should I choose?
Single girder suits lighter loads, shorter spans and lower duty. Double girder suits heavier loads, longer spans, more hook height and higher duty class. Our engineer recommends the right type after studying your load, span and use.
What does duty class M5 or M6 mean?
It shows how hard the crane will work. M5 is regular daily production use. M6 is frequent use, many hours a day, often near full load. Choosing the right class gives longer life and less downtime.
What documents do I get with the crane?
GA drawing, design calculations, quality assurance plan (QAP), material test certificates, load test certificate, operation and maintenance manual, and spares list.
How long does it take to supply an EOT crane?
It depends on capacity, span and design approval time. We share a clear schedule with the design proposal after the site study.
Do you provide AMC and service for cranes made by others?
Yes. We inspect, service and upgrade EOT cranes of any make in Jaipur and Rajasthan, and give a load test certificate after major repairs.
What is the price of an EOT crane?
Every crane is engineered for its load, span, lift and duty, so we give the price on request after a site study, with full technical details.
