Frequently Asked Questions
What is an explosion-proof overhead crane?
An overhead crane configured with electrical and mechanical protection for a specified hazardous area.
Is an Ex motor enough?
No. All mechanical and electrical components must be evaluated for the required area and ignition risks.
Can it be used for gas and dust environments?
Not automatically. Gas and dust require different classifications,groups and equipment requirements.
What information is needed for an initial
proposal?
Capacity, span, hazardous area classification, hazardous material and destination.
ATEX vs IECEx - What's the difference?
ATEX is an EU regulation. IECEx is an international conformity assessment system based on IEC and ISO standards.
Can it be supplied for Zone or Division
locations?
Yes, when the required zone, division, group, temperature rating and certification route are confirmed.
Can an existing crane be converted?
A conversion may be possible, but full review of ignition risks and the whole crane is required.
Can wireless remote control be used?
Yes, when control equipment is suitable for the hazardous area.
What documents can be supplied?
Certificates, Ex schedules, drawings, inspection records,manuals and conformity documents as agreed.
