Introduction to the Characteristics, Application Scope, and Operating Rules of Low Net Empty-Handed Gourd (Manual Chain Block) Products

I. Key Characteristics

Manual Operation and Portability

No Power Required: Operated by manually pulling the hand chain, eliminating the need for electricity or compressed air.

Lightweight and Compact: Designed for portability, making it suitable for confined spaces or remote job sites.

Load Capacity and Durability

Variable Load Ratings: Typically available in capacities from 0.5 tons to 20 tons, adaptable for various lifting tasks.

High-Strength Materials: Made from alloy steel for chains and hooks, ensuring resistance to wear, corrosion, and deformation.

Safety Features

Mechanical Brake System: Equipped with a self-locking brake (ratchet and pawl mechanism) that engages automatically when the hand chain is released, preventing uncontrolled descent.

Overload Protection: Some models include overload clutches to prevent damage from exceeding rated capacity.

Ease of Use and Maintenance

Simple Operation: Requires minimal training, with intuitive hand chain pulling and braking mechanisms.

Low Maintenance: Few moving parts reduce wear and tear. Regular lubrication and visual inspections of chains, hooks, and brakes are sufficient.

Cost-Effectiveness

Affordable: Cheaper than electric or hydraulic hoists, making it ideal for occasional or light-duty tasks.

No Running Costs: No energy expenses associated with manual operation.

II. Application Scope

Construction and Engineering

Lifting materials in areas without power access.

Positioning steel beams, formwork, or prefabricated components.

Maintenance and Repair

Replacing heavy machinery parts.

Lifting engines, pumps, or industrial equipment.

Warehousing and Logistics

Loading/unloading trucks.

Arranging inventory in storage facilities.

Agriculture and Farming

Lifting hay bales, feed sacks, or agricultural machinery.

Maintaining irrigation systems or farm structures.

Marine and Offshore

Lifting equipment on ships, docks, or offshore platforms.

Rescue operations or disaster recovery.

Home and DIY Projects

Lifting heavy objects during renovations.

Installing garage doors, HVAC units, or roofing materials.

III. Operating Rules

Pre-Operation Inspection

Chain and Hooks: Check for wear, corrosion, or deformation. Ensure hooks are not cracked or bent.

Brake System: Test the brake to ensure it engages smoothly and holds the load securely.

Gears and Bearings: Verify smooth rotation and listen for unusual noises.

Load Capacity: Never exceed the rated capacity.

Safe Operation

Clear Workspace: Ensure no obstructions are overhead or beneath the load.

Proper Rigging: Use slings or shackles rated for the load. Avoid sharp bends or kinks in chains.

Steady Pulling: Pull the hand chain evenly to avoid jarring or sudden movements.

Avoid Side Loading: Do not pull the load horizontally unless the hoist is designed for it.

Post-Operation Maintenance

Clean and Lubricate: Remove debris and lubricate moving parts after use.

Store Properly: Keep in a dry, covered area to prevent corrosion.

Regular Inspections: Follow a maintenance schedule to check for wear, fatigue, or damage.

Emergency Procedures

Stop Immediately: If unusual noises, vibrations, or resistance are detected.

Lower the Load Safely: Use the brake to lower the load gradually if the hoist malfunctions.

Do Not Force: Never force a stuck or jammed hoist—seek professional assistance.

Operator Training

Ensure operators are trained in safe use, load capacity limits, and emergency procedures.

Provide hands-on practice before allowing independent operation.
