The OZSR030-20CH Spark Resistant Chain Hoist is engineered for heavy-duty lifting in hazardous environments where safety, reliability, and compliance are critical. With a 3-ton (6,000 lbs) lifting capacity and a 20-foot lift height, this explosion-proof manual hoist is ideal for industries that handle flammable gases, vapors, or combustible dusts, providing consistent and secure lifting performance under extreme conditions.

Certified under EU standards ATEX94/9/EC and the Machinery Directive 2006/42/EC, the OZSR030-20CH meets the explosion-proof classification EX II2 GD c IIIC T135°C. This means it is suitable for Zone 1 & 2 (gas) and Zone 21 & 22 (dust) hazardous areas, ensuring operational safety in locations such as chemical processing plants, oil refineries, grain mills, and pharmaceutical manufacturing facilities.

This spark-resistant hoist is built using non-sparking materials such as bronze, brass, and stainless steel, which prevent ignition from mechanical friction or impact. The stainless steel Grade 80 load chain provides exceptional tensile strength, corrosion resistance, and long-term durability, even in corrosive or humid conditions. The precision-machined gears operate smoothly within a sealed steel housing, protecting internal components from dust and debris while reducing maintenance requirements.

The OZSR030-20CH features a mechanical Weston-style brake system, providing automatic load control and secure holding at any point of the lift. Its manual hand chain operation ensures precision lifting and lowering without the need for electrical power, making it an excellent choice for explosive or flammable work zones where powered equipment may pose a risk.

Both the top and bottom hooks are bronze-coated and equipped with safety latches to prevent accidental load release. The 20-foot lift height makes this model particularly suited for large-scale industrial environments, offering ample range for overhead lifting and high-clearance operations.
