Introduction to Hand-Pulled Hoist (Chain Block) Products

Hand-pulled hoists, also known as chain blocks or manual chain hoists, are portable, mechanical lifting devices used for vertical or horizontal lifting, lowering, or pulling loads. They are popular in applications where electrical power is unavailable or impractical. Below is an overview of their characteristics, application scale, and operating rules.

1. Characteristics

Simple Design: Compact structure with a hand chain for operation, gears, and a load chain.

Portability: Lightweight and easy to carry, suitable for mobile work sites.

Versatility: Can be used in vertical, horizontal, or inclined positions.

Cost-Effective: No electricity required, reducing operational costs.

High Durability: Robust construction for harsh environments.

Adjustable Capacity: Available in various load capacities (0.5–20 tons).

Safety Features: Include overload protection, brake systems, and corrosion-resistant materials.

2. Application Scale

Construction Sites: Lifting materials, equipment, or scaffolding.

Warehouses/Factories: Moving goods, machinery, or repairing equipment.

Automotive Repair: Lifting engines, transmissions, or heavy parts.

Mining/Tunneling: Handling equipment in confined spaces.

Agriculture: Lifting hay bales, farm machinery, or irrigation pipes.

Marine/Boating: Hoisting sails, anchors, or engines.

Emergency Rescue: Lifting debris or extracting trapped objects.

3. Operating Rules

Before Use

Inspect the Hoist: Check for cracks, wear, or damage to chains, hooks, gears, and brakes.

Verify Load Capacity: Ensure the hoist’s rated capacity matches or exceeds the load.

Test the Brake: Apply a light load and confirm the brake engages smoothly.

Secure the Load: Use slings, straps, or chains to attach the load securely to the hoist hook.

During Operation

Stand Clear: Keep bystanders away from the load path.

Pull Smoothly: Avoid sudden jerks on the hand chain to prevent overload or chain damage.

Maintain Balance: Keep the load chain aligned to avoid twisting or kinking.

Avoid Overloading: Never exceed the hoist’s maximum capacity.

Use in Vertical Mode: For horizontal pulls, ensure the hoist is designed for angled use.

After Use

Lower Load Slowly: Allow the brake to disengage gradually.

Store Properly: Clean and store in a dry, corrosion-free environment.

Lubricate Regularly: Apply oil to gears and chains to prevent rust and wear.

4. Safety Precautions

Never Modify the Hoist: Alterations can compromise safety.

Avoid Shock Loading: Do not drop loads suddenly.

Use Correct Anchors: Ensure the hoist is anchored to a stable structure.

Replace Worn Parts: Damaged chains, hooks, or gears must be replaced immediately.

Train Operators: Ensure users understand load limits and proper techniques.

5. Limitations

Speed: Manual operation is slower than electric hoists.

Height: Limited by chain length (typically 3–10 meters).

Environmental Sensitivity: Avoid exposure to extreme temperatures, chemicals, or moisture.
