Engineer lifting equipment for hazardous areas around zone classification, gas/dust group, temperature class, electrical components and project documentation.
Start with hazardous-area classification
Crane or hoist selection for a hazardous area needs the site owner’s classification data. Zone, gas or dust group and relevant environmental information should be supplied as project documentation.
- Zone classification
- Gas or dust group
- Ambient temperature
- Site classification document
One Ex motor does not define the system
A lifting system includes motor, brake, limits, controls, panel, cable connections, sensors and moving electrical components. Compliance review must cover the relevant components across the system.
- Motor and brake
- Limits and controls
- Panel and connections
- Sensors and accessories
Why temperature and protection ratings matter
Environment influences temperature class, ingress protection, corrosion requirements and maintenance approach. Equipment should not be selected against a classification that is missing from project data.
- Temperature class
- IP protection
- Corrosive environment
- Maintenance conditions
What documents belong in an RFQ
Provide hazardous-area classification, load and motion data, site layout, power supply, duty and required conformity/certification conditions together. Final equipment and documentation scope follows applicable project requirements.
- Zone document
- Load and motion
- Power and duty
- Conformity requirements
The quotation form organises load and site data into one WhatsApp message.
