Flame Proof Eot Cranes
Venus Engineers is a leading Flame Proof EOT Crane Manufacturer in Delhi, Gurgaon, NCR, and across India. Recognised among the most trusted EOT Crane Manufacturers in the country, we design and deliver Flame Proof EOT Cranes purpose-built for hazardous environments where flammable gases, combustible vapours, chemical fumes, or explosive dust are present in the atmosphere. Engineered in compliance with IS 3177, IS 4137, and IEC 60079 standards, our Flameproof EOT Cranes deliver the same lifting efficiency and precision as a conventional EOT Crane — with every electrical and mechanical component rated and certified for explosive atmospheres. With load capacities from 1 tonne to 50 tonnes, Venus Engineers provides a safe, reliable, and fully compliant material handling solution for India's most demanding hazardous-area industries.
Why Hazardous Environments Need a Specialised Crane
In industries where flammable substances are processed, stored, or transported, a standard EOT Crane presents a serious ignition risk. Conventional motors, brake systems, control panels, and limit switches generate electrical arcs and surface heat that can ignite explosive atmospheres — with potentially catastrophic consequences.
A Flame Proof EOT Crane eliminates this risk entirely. Every component that carries electrical current — the hoist motor, travel motors, brakes, control panels, limit switches, junction boxes, and pendant stations — is housed in certified explosion-proof enclosures that contain any internal ignition and prevent it from reaching the surrounding atmosphere. The result is a crane that performs all standard material handling functions while meeting the strictest industrial safety regulations for hazardous locations.
As experienced Flame Proof EOT Crane Manufacturers, Venus Engineers designs cranes for Zone 1 and Zone 2 hazardous areas as classified under IS 5572 and IEC 60079-10, available in both single girder and double girder configurations to match your facility's capacity and span requirements.
Configurations We Offer
Single Girder Flameproof EOT Crane
Built on a single box or I-beam girder, this configuration carries flameproof-rated hoists and travel mechanisms for capacities up to 10 tonnes. It is the preferred choice for smaller chemical processing units, pharmaceutical plants, and paint shops where headroom is limited and the hazardous zone is contained within a single bay.
Best for: Chemical storage areas, paint booths, pharmaceutical processing, solvent handling areas, small petrochemical units
Double Girder Flameproof EOT Crane
Two parallel box girders carry a flameproof crab trolley mechanism, delivering capacities from 5 tonnes to 50 tonnes across long spans. Specified for large-scale refineries, heavy chemical plants, and gas processing facilities where high-cycle, heavy-duty lifting is required in a continuously hazardous atmosphere.
Best for: Oil refineries, petrochemical complexes, LPG and gas processing plants, explosive manufacturing, large chemical process industries
