Product Description
The Columbus McKinnon STAHL® SK Series redefines industrial lifting with its modular, explosion-proof design engineered for extreme environments. As one of the industry’s most adaptable hoists, it combines ATEX/IECEx Zone 1/21/22 certification with Columbus McKinnon’s 140+ years of lifting expertise to deliver unmatched safety in chemical plants, mining, and oil/gas facilities.
Core innovations include a patented chain guide system for reduced wear, dual-speed control via IP65-rated pendants, and electromagnetic brakes with visible safety indicators. The hoist’s open-architecture design allows rapid maintenance, while its FEM-compliant load chains ensure longevity under high-duty cycles.
Customization is integral to the SK Series:
Explosion-Proof Engineering: All components modified for gas/dust hazards.
Application-Specific Configurations: Dual-hoist systems, coupling hoists for multi-point lifts, or STB Big Bag variants.
Global Support: Localized production ensures fast delivery of bespoke solutions.
For operations demanding zero compromises in safety or flexibility, the SK Series delivers future-proof performance backed by IEC 60079 quality certification.
