The OZSR100-20CH Spark Resistant Chain Hoist is designed for heavy-duty industrial lifting where explosion-proof safety and durability are essential. With an impressive 10-ton (20,000 lbs) capacity and a 20 ft lift height, this manual chain hoist delivers superior performance in hazardous and explosive environments, ensuring safe and efficient material handling in compliance with the strictest international standards.

Engineered to meet ATEX94/9/EC and Machinery Directive 2006/42/EC requirements, the OZSR100-20CH achieves an explosion-proof rating of EX II2 GD c IIIC T135°C, making it suitable for Zone 1 & 2 (gas) and Zone 21 & 22 (dust) areas. This certification guarantees that the hoist is safe for use in environments with flammable gases, vapors, or combustible dust—such as oil refineries, chemical processing plants, and grain handling facilities.

Built with spark-resistant materials, including bronze hooks, brass gears, and stainless steel load chains, this hoist eliminates the risk of spark generation during operation. Its robust all-steel construction with a fully enclosed gear housing protects internal mechanisms from dust, dirt, and moisture—ensuring long-term reliability and minimal maintenance, even under demanding conditions.

The Grade 80 stainless steel load chain offers exceptional tensile strength and corrosion resistance, while the precision-machined hand chain wheel allows smooth, effortless lifting with minimal manual force. Safety remains a top priority, supported by a Weston-style mechanical load brake that securely holds the load in place, preventing accidental lowering. Additionally, swivel top and bottom hooks with safety latches enhance versatility and load security during use.

Because it operates manually, the OZSR100-20CH does not rely on electricity or pneumatic systems, eliminating the risk of electrical ignition. This makes it an ideal solution for hazardous environments where power-driven hoists cannot be safely used.
