Взрывозащитные мостовые краны

In the chemical and petrochemical industry, at mineral oil and natural gas production, in the mining industry and several other industry branches inflammable materials, gasses, fumes escape during production, processing, transport and storing. Explosion danger may occur when inflammable dust develops during production (e.g. flour).

These inflammable materials become combustible mixtures, when mixed up with the oxigen of the air. In this atmosphere any source of ignition (flame, electric or mechanic spark etc.) can cause an explosion, which may result in heavy personal and
material loss. That means we have to handle the electric device like a possible ignition source. Because of that all the electric equipment of a crane has to be explosion protected.

STAHL Crane Systems, Europe biggest manufacturer of explosion protected electric equipment and crane components offer complete safety with explosion protected cranes due to their long-lasting experience.
