The OZSR005-30CH Spark Resistant Chain Hoist is designed for maximum safety, precision, and reliability when lifting in explosive or hazardous environments. With a 0.5-ton (1,000 lbs) lifting capacity and a 30-foot lift height, this hoist delivers dependable performance for applications where standard lifting equipment cannot be safely used. Built to meet the highest safety standards, it ensures protection against ignition risks caused by mechanical sparks, making it ideal for Zone 1 & 2 (gas) and Zone 21 & 22 (dust) classified areas.

Engineered for compliance with ATEX Directive 94/9/EC and Machinery Directive 2006/42/EC, the OZSR005-30CH achieves an explosion-proof certification of EX II2 GD c IIIC T135°C. This ensures reliable use in facilities where flammable gases, vapors, or combustible dust may be present—such as chemical plants, refineries, food processing facilities, and energy production environments.

Constructed from premium spark-resistant materials, this hoist incorporates bronze, stainless steel, and aluminum-bronze alloys in critical areas, preventing spark formation during operation. The all-steel housing provides superior durability, while the fully enclosed gear system keeps internal components protected from dust and contaminants for consistent, low-maintenance performance.

The Weston-style mechanical brake system, equipped with a twin pawl design, offers reliable load control and safety by automatically engaging under load, preventing accidental drops. The Grade 80 stainless steel load chain delivers exceptional tensile strength, corrosion resistance, and smooth operation for long service life even in harsh or humid conditions.

Both top and bottom hooks feature spark-resistant bronze coatings, heavy-duty safety latches, and a 360° swivel for ease of positioning. The ergonomic hand chain ensures efficient manual operation with minimal effort, making lifting tasks safer and easier for operators. A durable powder-coated finish resists wear and chemical corrosion, ensuring lasting protection in challenging environments.
