Explosion protected lifting and handling equipment for use in potentially explosive atmospheres, across hoists, trolleys and trucks.




Where flammable gas, vapour or dust can be present, ordinary equipment can provide the ignition source. ATEX-rated equipment is built so it cannot — through spark-resistant materials, controlled surface temperatures and sealed construction. It is specified by the zone it will work in, not by the job it does.
Zones describe how often an explosive atmosphere is present and whether the hazard is gas or dust. Equipment is certified for particular zones and groups, so the site's hazardous area classification decides what you can use. If nobody can tell you the zone, that is the question to resolve first — it is not something to assume from the type of site.
Rating the hoist and then hanging it from an uncertified trolley or using a standard chain sling defeats the point. Every item that goes into the hazardous area needs to be suitable, including slings, shackles and any powered accessory.
From the site's hazardous area classification, which sets the zone and whether the risk is gas or dust. Ask the site or the responsible person for it rather than working it out from the type of premises.
Not inside the hazardous area. Every item entering the zone needs to be suitable, including slings, shackles and trolleys, or the protection is lost.
The lifting technique is the same, but the equipment must not be modified, repaired with non-original parts, or used outside the conditions it was certified for.
