Temperature classes:
The max. surface temperature of the operating material must always be less
than the ignition temperature of the gas-vapour-air mixture. Operating materials which
are classed in higher temperature classes are approved in all areas where lower
temperature classes are required.

I n potentially explosive areas with combustible dusts, the surfaces should
not exceed a temperature which is 2/3 of the ignition temperature in °C of
the dust/air mix. The indication of a temperature class related to the hoist
assumes an ambient temperature between -20°C and +70°C.
The heat resis tance of the chains and hooks is +150°C. For stationary
outdoor operation, the stand ard chain hoists must be protected from the
weather and maintenance intervals must be reduced.
