Applicable Uses of Explosion Proof Overhead Crane

This product is applicable in sites where the explosive substances and ignition sources are present, especially in plants where the explosion transfer capacity is not higher than IIB or IIC and the ignition temperature is in a range of T1-T4 group. The cranes are engineered to perform light duty and moderate lifting requirements.

Light duty service: this service class refers to light lifting requirements that cover small capacity and slow lifting speed. Within this service requirements, the explosion proof bridge crane will be built on request.

Moderate service: the crane designed with moderate service requirements indicates that the crane is able to handle heavier loads and realizes a greater lifting speed.

In the selection process of an overhead crane, the potential crane users should specifically define the rated load weight, working environment and the type of explosive gas or mixture so that the crane manufacturer can determine the level of explosion protection and duty cycle.
