5 Ton Industrial Electric Hoist Corrosion Resistant Stainless Steel Electric

The KOEO EQ05-02 is a premium 5 ton stainless steel electric chain hoist engineered for the most demanding corrosive environments including food processing facilities, chemical manufacturing plants, pharmaceutical production lines, marine and offshore installations, and wastewater treatment operations. Constructed with an AISI 304 stainless steel housing, AISI 316 stainless steel load chain, and IP55 sealed motor enclosure, the EQ05-02 provides complete corrosion resistance against salt spray, acid fumes, alkaline cleaning solutions, and high-pressure washdown procedures. The twin 3.0 kW motor configuration with Class H (180°C) insulation, dual sealed electromagnetic brakes, and food-grade lubrication on all moving components make this hoist the definitive heavy lifting solution for hygiene-critical and chemically aggressive industrial environments.

• Full Stainless Steel Construction: The hoist body, chain guides, load sheave, and hook assembly are manufactured from AISI 304 stainless steel. The load chain is fabricated from AISI 316 stainless steel with enhanced molybdenum content for superior resistance to chloride-induced pitting corrosion in marine and chemical processing environments.
• IP65 Fully Sealed Twin Motor System: Dual 3.0 kW motors feature IP55-rated sealed enclosures providing complete protection against dust ingress and low-pressure water jets from any direction. The sealed design withstands daily high-pressure washdown procedures common in food processing and pharmaceutical cleanroom operations.
• AISI 316 Stainless Steel Load Chain: Premium AISI 316 stainless steel chain with 11.2 mm diameter and 4:1 safety factor. The molybdenum-alloyed 316 grade provides exceptional resistance to chlorides, sulfuric acid compounds, and alkaline cleaning agents that rapidly degrade conventional carbon steel and G80 alloy chains.
• Class H (180°C) Insulation System: Upgraded Class H insulation rated to 180°C provides substantial thermal headroom for operation in high-temperature cleaning environments, autoclave sterilization areas, and chemical process zones where ambient temperatures regularly exceed standard industrial conditions.
• Dual Sealed Electromagnetic DC Brakes: Two independent electromagnetic DC brakes with fully sealed stainless steel housings prevent moisture and chemical ingress into braking surfaces. Food-grade synthetic brake lining material contains no asbestos or heavy metals, meeting FDA indirect food contact requirements.
• Electropolished Surface Finish: All external stainless steel surfaces receive an electropolishing treatment that removes surface iron contamination, creates a microscopically smooth Ra ≤ 0.5 µm surface finish, and enhances the natural passive chromium oxide layer for maximum corrosion resistance and cleanability.
• IP65 Sealed Pendant Controller: The 36V pendant control features a fully sealed IP55-rated housing with silicone membrane buttons and stainless steel faceplate. The smooth, crevice-free design eliminates bacteria harborage points and withstands chemical disinfectant wiping required in pharmaceutical and food processing environments.

The EQ05-02 stainless steel electric chain hoist is purpose-engineered for meat and poultry processing facilities requiring daily high-pressure washdown, seafood processing plants with constant saltwater exposure, pharmaceutical cleanroom material handling, chemical manufacturing reactor charging operations, offshore oil and gas platform auxiliary lifting, wastewater treatment plant equipment maintenance, and marine shipyard applications with direct seawater spray. The complete stainless steel construction and IP55 sealing enable reliable operation in environments where conventional hoists fail within weeks due to corrosion damage.

Each EQ05-02 hoist is packed in a KOEO-branded heavy-duty plywood case with VCI anti-rust film, reinforced stainless steel internal bracing, high-density closed-cell foam padding, and industrial-grade silica gel desiccant packs. The export-grade outer carton features stainless steel banding and vacuum-sealed moisture barrier for long-term storage and international ocean freight. Every unit undergoes 100 percent factory load testing at 1.25 times rated capacity (6.25 tons) with full documentation including material certificates for all stainless steel components, surface finish measurement reports, and IP65 enclosure integrity test results. CE certified in compliance with EU Machinery Directive 2006/42/EC. Manufactured under ISO 9001:2015 quality management systems. FDA-compliant materials used for all food contact surfaces. AISI 316 chain certified with full mill test reports including chemical composition and mechanical properties. Standard delivery within 10 to 15 working days for stock models and 25 to 35 days for custom production orders.
