Our explosion proof cranes with wire rope hoist are widely used for the oil, gas, chemical, petrochemical and pharmaceutical industries, the food processing industry as well as the power supply, shipbuilding, offshore and other explosive environments.
Safety and reliability is especially important in hazardous environments, where safety and efficiency are key. All crane components of our explosion proof cranes are selected to ensure the high level of safety required for the hazardous atmospheres in chemical and petrochemical plants, pharmaceutical, oil refineries, gas power plants, shipyard, waste water treatment plants, paint shops and other industrial sites. Our hoists have been designed and built to provide years of reliable and safe operation.

Definition for Hazardous Locations According to ATEX
Ex Zones – Gas Environment
A place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.
A place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
Ex Zones – Dust Environment
A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally.
A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
Explosion Hazardous Areas Zones Separation
Probability of an explosive atmosphere
Very High –Explosive atmosphere is continual or very frequent.
High –Explosive atmosphere is occasional.
Low – Explosive atmosphere rarely occurs.
