Explosion proof protection

How to avoid explosion ? To avoid the creation of an explosive environment or atmosphere is naturally the first option and the most easiest way with high safety. For example, to provide the adequate and effective ventilation or confine the work processes to prevent the appearance of dangerous gases or dusts in the closed system.

Secondly, to prevent the explosive atmosphere from ignition is also an effective to prevent explosion . To justify this aim, the surface temperature of the explosion proof equipment must be limited and the creation of sparks or sources of ignition must be avoided.

Lastly, the effects of an explosion must be controlled and reduced to a negligible level. Usually, it is conducted by isolating the ignition source, e.g. by mounting explosion proof equipment in flameproof enclosures, etc.

Explosion proof hoist and crane use the explosion protection of removal of potential sources of ignition to prevent explosion by adopting specialized hoist parts & components and together with ongoing monitoring of potentially hazardous environments. What's more, the explosion proof hoist and crane are also used in explosion proof and flame proof workshops.

Explosion proof crane systems are available with various overhead crane designs including single girder overhead cranes, double girder overhead cranes, top running overhead cranes & under hung overhead cranes, equipped with explosion proof hoists for hazardous applications, and anti-explosion and spark resistant crane parts and components for hazardous industrial applications such as oil rigs, gas liquefaction plants , mines or chemical industry and other various hazardous applications wherever explosive gases or dusts predominate may have the potential of existing.

Note on explosion proof overhead crane zoning

Hazardous areas are categorized into zones according to the assessment of the frequency of the occurrence and duration of an explosive atmosphere. A zone is an area in which an explosive gas atmosphere:

• is present continuously or for long periods of time, Zone 0;
• is likely to occur in normal operation, Zone 1;
• is not likely to occur in normal operation and, if it occurs, will only exist for a short time. Zone 2.
• Explosion Proof overhead crane Zoning: Zone 1 & Zone 2 Hazardous Areas
