• Durable Hand Chain: Made from high-strength galvanized steel with rust-resistant coating, designed for long-term industrial use.
• Precision-Cut Gears: Ensures seamless and quiet movement for smooth door opening and closing cycles.
• Heavy-Duty Housing: Reinforced steel casing offers maximum protection to internal gears and chains under heavy load conditions.
• Universal Mounting Options: Suitable for both shaft-mount and wall-mount installations for commercial sectional doors.
• Safety Brake System: Integrated self-locking mechanism prevents accidental door drop or slippage.
• OEM & Customizable Design: Fully customizable chain length, bracket style, and gear ratio options available to meet your specific requirements.

🔩 Technical Specifications

🏭 Built for Performance & Longevity

Our Garage Door Chain Hoist is designed with a focus on safety, durability, and user efficiency. Each unit is tested for torque, alignment, and smooth rotation to ensure consistent performance under continuous operation. The compact yet strong design makes it suitable for large door panels commonly used in logistics centers, automotive workshops, and warehouse loading bays.

Featuring a precision-engineered 4:1 gear ratio, it minimizes manual effort while maintaining full control over door movement. This mechanical advantage helps operators safely lift and lower doors without motor assistance — an ideal solution where electricity is unavailable or backup manual operation is required.
