Explosion-Protected Hoists – Safe lifting in Ex zones for industry

Planning hoists for hazardous areas

Explosion protection cannot be selected from load capacity alone. The hazardous zone, substance group, temperature class and site operating conditions must be defined before equipment is chosen. The complete lifting arrangement—including hoist, trolley, controls and accessories—has to be suitable for the intended area and used according to its marking and documentation.

For technical clarification, provide the required capacity and lift together with the zone classification, ambient conditions, duty cycle and available energy supply. Existing site documentation and photographs help SHT assess the request. Installation, inspection and maintenance requirements should be considered at the same time so that the equipment remains accessible and traceable throughout its service life.

Changes to the operating area or to connected components can affect the original assessment. Any later modification should therefore be reviewed before the equipment is returned to service.
