Stahl: Experts in Explosion Protection

As one of the leading manufacturers of explosion-proof lifting and crane technology, STAHL CraneSystems offers a broad and complete portfolio of products as well as comprehensive services in this field. Explosion-protected products from STAHL CraneSystems meet not only German national laws and European ATEX directives but also international standards and laws for the American and Asian market. For example, all products are certified both to ATEX and IECEx.

Stahl product types are certified after passing an EC prototype test and undergo the conformity assessment procedure specified in the directives. Development and manufacture of the series products are subject to our strict quality management monitored by independent European inspection authorities. The test certificates from the notified European inspection authorities are recognised throughout the EU.

The rating plates indicate in addition to the usual data (manufacturer, type, serial number, electrical data) the data relevant to explosion protection. CE marking of the products, declaration of conformity in writing and detailed operating instructions and documentation confirm that all valid EU directives applicable to the apparatus are observed.

Decades of experience in the field of explosion protection, responsible, expert staff and production in accordance with the latest directives and standards guarantee quality down to the last detail for every piece of
explosion-protected equipment from STAHL CraneSystems.

The components and electrics, which also meet the European product directive 2014/34/EU (ATEX 95) and the international IECEx regulations, are the perfect complement to explosion-protected lifting technology from STAHL CraneSystems.

The correct functioning and high performance of a crane system depend on the quality of all its components. These are developed down to the last detail by STAHL CraneSystems and supplied from our own production. Forward-looking, high-quality modules complement one another in the system and ensure both safety and cost-effectiveness. Using the modular components, our crane manufacturing partners in your region are able to adapt the crane system individually to customer-specific requirements and wishes. Mature, cost-effective electronics, drive technology to meet the highest demands, innovative modules and field-proven, robust standard components are available for these adaptations. The expert crane manufacturing partners and experienced system manufacturers are trained by STAHL CraneSystems’ explosion protection experts so that they are always up to date as regards the status of national and international regulations and state-of-the-art technology.

Bottom Hook Block

For high and very high travelling speeds the load hook and the solid parts of potential impact surfaces are bronze-coated. In addition, all other exterior surfaces of the bottom hook block can be bronze coated to prevent sparking.

Panel Box

Flameproof enclosure for Zone 1 and Zone 2: the sheet steel or aluminium housings can be used as individual housings or in combination. All components required such as transformers, contactors, fuses, measuring instruments and tripping devices can be installed in the modular-design housing. Post-type bushings provide the connection
to the terminal box (in increased safety Ex e).

Travel Drive

The explosion-protected travel drives Zone 1 and Zone 21 are designed for intermittent operation. They have a sliding rotor motor with conical brake and centrifugal mass for smooth starting and braking characteristics. All motors are pole-changing providing two travel speeds. The particularly quiet gear requires little maintenance thanks to its long-term oil bath lubrication.

Crane End Carriages

Crane systems up to a safe working load of 50,000 kg and a span of 30 m can be built with explosion-protected end carriages for underhung and overhead travelling cranes. For particular applications, at customers’ request and for increased safety all wheels can be supplied in brass.

Control Pendants

The SWH 5 Ex control pendants are designed specifically for controlling hoists and cranes in hazardous areas.
