Explosion Proof Overhead Crane

Explosion proof overhead crane introduction

Explosion proof overhead crane is one of the various types of explosion-proof and hazardous environment overhead crane. All the motors and electrical equipment are explosion proof. The explosion proof level is in line with international standards and regulations. The lifting capacity of the explosion proof overhead crane is 5 to 75 tons and the working class is A4 and A5, and the specific parameters is shown in the following diagram:

Components of Explosion proof crane

The explosion proof crane offered by DQCRANES is mainly consisted of bridge structure, lifting mechanism, crane traveling mechanism, electric equipment, etc.

Explosion Proof 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:

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

Application of Explosion proof overhead crane

The explosion proof marks are Exd Ⅱ BT4 and Exd Ⅱ CT4.

Explosion proof overhead crane is applied to sites, where is not higher than the II B or II C-class, and the sites with explosive air mixture formed with inflammable gas (or steam) and air whose factory ignition temperature groups of not less than the T4 group.

Dongqi Crane designs and manufactures explosion proof overhead crane for the harsh and hazardous application environments, such as, chemical plants, gas power plants, paint shops, oil refineries, and waste water treatment plants, etc.
