ATEX Crane Scales – Certified Overhead Weighing for Hazardous Areas
Our ATEX crane scales are certified suspended weighing instruments designed for accurate overhead load measurement in potentially explosive atmospheres. Approved for Zone 1, Zone 2, Zone 21, and Zone 22 classified hazardous areas, they provide a safe solution for lifting and weighing operations in chemical plants, oil and gas facilities, pharmaceutical manufacturing, paint production, and any environment where flammable gases, vapours, or combustible dusts may be present alongside overhead handling operations.
Combining the functionality of a standard crane scale — high-capacity suspended weighing, wireless remote display, and overload protection — with the intrinsically safe or explosion-proof engineering required for ATEX certification, these scales allow operators to weigh suspended loads safely without removing equipment from the hazardous area. Robust stainless steel and aluminium construction with IP65 or higher protection ratings ensures reliable performance in the demanding chemical and process environments where ATEX equipment is typically required. Full ATEX certification documentation is supplied with every unit.

Frequently Asked Questions
What ATEX zones are these crane scales certified for?
Our ATEX crane scales are certified for Zone 1 and Zone 2 (gas and vapour explosive atmospheres) and Zone 21 and Zone 22 (combustible dust explosive atmospheres). Zone 1 certified equipment can also be used in Zone 2 areas. Always confirm the zone classification of your specific installation before selecting equipment — contact our team for guidance.
Can the wireless display be located outside the hazardous zone?
Yes. Many ATEX crane scale systems use an intrinsically safe design where the load cell and hook assembly are located in the hazardous zone, with the wireless display unit positioned in a safe area. This reduces the amount of ATEX-certified equipment required in the hazardous zone and allows operators to read weight data from a safe location. Confirm the system configuration with our team for your specific zone layout.
Are ATEX crane scales safe to use during active lifting operations?
Yes, when used within their rated Safe Working Load (SWL) and in accordance with the manufacturer’s guidelines and your site lifting procedures. All models include overload protection to prevent damage from accidental overloading. For lifting in hazardous areas, always ensure the crane scale’s SWL meets or exceeds the maximum load and that all lifting equipment used alongside it is also rated for the hazardous area.
Do I need a DSEAR risk assessment before purchasing ATEX crane scales?
Yes. Under UK DSEAR, employers must carry out a risk assessment to classify hazardous zones and specify the correct equipment category. ATEX crane scales must be selected to match the zone classification determined by this assessment. Our technical team can advise on the correct specification once you have your zone classification confirmed by a competent person.
Is UKAS calibration available for ATEX crane scales?
Yes. UKAS-traceable calibration certificates are available on request. Calibration in hazardous areas must follow appropriate safe working procedures for the classified zone. Contact our team for calibration and service support specific to your hazardous area environment and lifting application.
