The OZSR050-30CH Spark Resistant Chain Hoist delivers superior lifting performance and explosion-proof safety for industrial operations in hazardous environments. With a 5-ton (10,000 lbs) load capacity and a 30-foot lift height, this heavy-duty manual chain hoist is built for applications where safety, reliability, and strength are critical. Designed for use in flammable or explosive atmospheres, it provides peace of mind for industries such as oil and gas, petrochemical, paint manufacturing, and food processing.

Built to meet the strictest safety requirements, this hoist fully complies with EU Directive ATEX94/9/EC and the Machinery Directive 2006/42/EC, achieving an explosion-proof level of EX II2 GD c IIIC T135°C. This rating ensures safe operation in Zone 1 & 2 (gas) and Zone 21 & 22 (dust) areas—making it ideal for environments where flammable gases, vapors, or combustible dust are present.

The OZSR050-30CH features spark-resistant components, including bronze hooks, brass gears, and stainless steel load chains, to prevent ignition caused by friction or static discharge. The Grade 80 stainless steel chain ensures exceptional durability, corrosion resistance, and smooth load handling under heavy stress. The precision-machined gears and hand chain mechanism allow for effortless operation, reducing operator fatigue and improving control during lifting or lowering operations.

For dependable safety, this model includes a Weston-style mechanical brake system with dual pawl engagement, ensuring secure load holding even in the event of accidental slippage. The top and bottom swivel hooks include safety latches to prevent unintentional load release, while the fully enclosed steel housing protects internal components from dust, moisture, and corrosion—making it ideal for both indoor and outdoor applications.

The manual operation eliminates electrical ignition risks, offering a safe, maintenance-friendly lifting solution for explosion-prone work zones. Whether in chemical plants, offshore platforms, or grain silos, the OZSR050-30CH provides unmatched reliability, ensuring that every lift is safe, smooth, and spark-free.
