The OZSR050-20CH Spark Resistant Chain Hoist is expertly designed for lifting operations in explosive or hazardous environments, where safety and reliability are top priorities. With a 5-ton (10,000 lbs) lifting capacity and a 20-foot lift height, this heavy-duty manual hoist provides exceptional performance, ensuring operators can lift and lower loads safely in areas exposed to flammable gases, vapors, or combustible dusts.

Engineered to meet stringent European safety standards, the OZSR050-20CH is fully compliant with ATEX94/9/EC and the Machinery Directive 2006/42/EC, featuring an explosion-proof rating of EX II2 GD c IIIC T135°C. This certification makes it suitable for Zone 1 & 2 (gas) and Zone 21 & 22 (dust) environments—ideal for industries such as oil and gas, chemical processing, paint manufacturing, grain handling, and pharmaceuticals.

Built with spark-resistant materials, including bronze hooks, brass gears, and stainless steel load chains, the OZSR050-20CH minimizes ignition risks caused by static discharge or friction. Its Grade 80 stainless steel chain provides superior strength, corrosion resistance, and smooth operation under load. The Weston-style mechanical brake system with dual pawl engagement ensures reliable load control and holding capability, even in the most demanding conditions.

The hoist’s precision-machined gears offer smooth hand chain operation, reducing operator fatigue while maintaining exacting control. The swivel hooks with safety latches enable flexible load positioning and secure attachment, preventing accidental unhooking during lifting. Additionally, the fully enclosed steel housing protects internal components from dust, debris, and harsh environments, extending the life of the hoist and maintaining consistent performance.

The manual operation of the OZSR050-20CH eliminates electrical components, ensuring it remains safe and functional even in high-risk explosion zones. Its robust construction, low maintenance requirements, and spark-resistant finish make it an essential choice for operations that demand durability and total safety assurance.
