Universal electric hoist
Weiyuan 1-Ton Stainless Steel Cleanroom Electric Chain Hoist

Tagline: Zero-Contamination Precision Lifting Mechanism for Sanitary & Ultra-Clean Facilities
1. Product Overview
Designed to meet stringent ISO Class 5 cleanroom standards, the Weiyuan 1-Ton Stainless Steel Electric Chain Hoist eliminates particulate generation and lubricant leakage. Constructed with AISI 304/316 polished stainless steel housings, food-grade synthetic lubricants, and a sealed non-shedding chain container, this hoist delivers ultra-smooth, contamination-free lifting in sanitary manufacturing environments.
2. Key Advantages & Technical Highlights
- Corrosion-Proof AISI 304/316 Stainless Steel Structure: Fully sealed, IP66-rated stainless steel housing withstands aggressive chemical washdowns and sterilizing agents.
- Zero-Particulate & Food-Grade Lubrication: Employs NSF H1 compliant food-grade lubricants and self-lubricating non-metallic chain guides to eliminate oil drips.
- Ultra-Smooth Stepless VFD Control: Inverter-driven micro-speed adjustment guarantees vibration-free positioning of delicate, high-value payloads.
- Hygiene-Focused Sealed Design: Smooth curved surfaces prevent dust accumulation, paired with a heavy-duty polyester/stainless chain collector bag.
