The OZSR020-20CH Spark Resistant Chain Hoist is engineered for maximum safety and durability in hazardous environments where flammable gases, vapors, or combustible dusts are present. With a 2-ton (4,000 lbs) lifting capacity and 20-foot lift height, this explosion-proof hoist offers exceptional performance, reliability, and compliance with strict international safety standards.

Built to meet the EU ATEX94/9/EC and Machinery Directive 2006/42/EC standards, this hoist achieves an explosion-proof rating of EX II2 GD c IIIC T135°C, making it fully suitable for Zone 1 & 2 (gas) and Zone 21 & 22 (dust) classified areas. The OZSR020-20CH ensures dependable lifting operations in critical industries such as oil and gas, petrochemical, food processing, and pharmaceuticals, where ignition control and operational safety are essential.

Constructed with non-sparking components—including bronze, brass, and stainless-steel parts—this hoist minimizes the risk of spark generation caused by friction or impact. The Grade 80 stainless steel load chain provides outstanding tensile strength, wear resistance, and smooth chain movement, even under the most demanding loads.

The fully enclosed precision gearing system allows for low-effort lifting while protecting internal mechanisms from contaminants like dust and moisture. Additionally, the Weston-style twin pawl brake system delivers consistent load control and prevents accidental descent, ensuring safe handling of heavy loads at all times.

The OZSR020-20CH is equipped with bronze-coated swivel hooks—both top and bottom—for easy positioning and secure attachment. Each hook includes safety latches to prevent unintentional disengagement. The powder-coated steel housing resists corrosion and damage from environmental exposure, extending the hoist’s operational lifespan in industrial settings.

With a 20 ft lift, this spark-resistant hoist offers extended reach for overhead lifting applications in facilities requiring strict adherence to explosion-proof safety standards. Its manual chain operation ensures precise load control without the need for an electrical power source—ideal for zones where electrical equipment could pose an ignition hazard.
