The OZSR005-20CH Spark Resistant Chain Hoist is built for maximum safety and dependability in hazardous and explosive work environments, offering a 0.5-ton (1,000 lbs) lifting capacity with a 20 ft lift height. Designed with advanced engineering and premium materials, this manual chain hoist ensures safe operation where flammable gases, vapors, or dust are present. It’s the ideal choice for industries such as oil and gas, chemical processing, food production, and power generation—anywhere explosion protection is critical.

Engineered to meet strict international safety regulations, this hoist complies with EU ATEX Directive 94/9/EC and Machinery Directive 2006/42/EC. It achieves an explosion-proof protection level of EX II2 GD c IIIC T135°C, making it suitable for Zone 1 & 2 (gas) and Zone 21 & 22 (dust) hazardous areas. The spark-resistant components are crafted from high-quality materials such as bronze, stainless steel, and aluminum-bronze alloys, ensuring safe use without the risk of spark generation in volatile environments.

The OZSR005-20CH features a robust all-steel housing that protects internal components from impact and contaminants. Its fully enclosed gearing system ensures smooth, low-resistance operation while preventing dust or moisture from affecting performance. A Weston-style mechanical brake system with a twin pawl design guarantees secure load holding and precise control, automatically engaging under load for maximum safety.

Equipped with a Grade 80 stainless steel load chain, the hoist provides outstanding strength, corrosion resistance, and long service life. The bronze-coated top and bottom hooks are fitted with heavy-duty safety latches and rotate 360°, enhancing safety and ease of positioning during lifting operations. The ergonomic hand chain operates smoothly and efficiently, reducing operator fatigue even during repetitive use.

The durable powder-coated finish further protects the hoist from corrosion and chemical exposure, making it a long-lasting investment for industrial operations that demand safety, performance, and reliability.
