Manual Lifting Chain Block Hoist Hand for Lifting Pulling

High-Strength Material & Durability

Lever hoists are constructed from high-grade alloy steel, with critical components heat-treated to achieve up to 800MPa tensile strength. The corrosion-resistant coating extends service life by 30%+, making them suitable for harsh environments like construction sites and shipyards.

Compact & Versatile Operation

Weighing only 5-25kg, these hoists are ideal for confined spaces. The dual-pawl ratchet system enables 2x faster lifting, while the 360° rotating handle allows operation in any position. Suitable for vertical lifting, horizontal pulling, and load positioning.

Low Maintenance & Cost-Effective

Sealed bearings and self-lubricating gears reduce wear, requiring only annual inspections. Compared to electric hoists, they cut energy costs by 100% while delivering 0.5-3m/min lifting speeds.

Hand cranked hoist is a lightweight and flexible manual lifting tool, and its specific application scenarios are as follows:

1. Construction site: used for lifting small building materials, installing components, etc.

2. Warehouse logistics: Goods can be moved and shelves can be loaded and unloaded in the warehouse.

3. Power maintenance: Convenient for power workers to carry out equipment maintenance and line adjustment at heights.

4. Car maintenance: It can assist in lifting car parts for easy maintenance operations.

5. Shipbuilding: Used for lifting components in ship construction and maintenance.

6. Mining operations: Assist mining workers in equipment installation and material handling.

7. Bridge construction: Install and adjust small components of the bridge.

8. Agricultural production: such as lifting agricultural products or repairing agricultural equipment on farms.

Product Operate Guide

1. Pre use inspection

Check whether the chain is intact and free of deformation/rust, confirm that the brake is flexible and reliable, test whether the no-load operation is smooth, and verify that the load does not exceed the rated weight

Warning: Do not use damaged gourds!

2. Proper suspension

Hang the upper hook firmly on the support point to ensure that the support structure can withstand 1.5 times the load, hang the heavy object vertically on the lower hook, and check whether the double hook anti detachment device is effective

Tip: The suspension angle should not exceed 30 °

3. Smooth operation

Apply even force to the handle, pulling it backwards when lifting and pushing it forwards when lowering to avoid sudden force or impact

Attention: Keep the chain vertical during operation

4. Pause midway

Release the handle to automatically lock, and the heavy object will remain in its current position. It is prohibited to suspend the heavy object for a long time, and a safety rope should be added for temporary parking

Warning: Do not leave the post while suspended

5. Maintenance after use

Clean the chain and lubricate it for maintenance

Store in a dry environment, conduct regular load tests, and record usage

Suggestion: Professional testing every six months

Safety signs:

Overloading is prohibited for use

Prohibition of modifying equipment

Wear protective gloves during operation

Q1. How does a hand-operated hoist work?

A: Gear transmission: When the handle is pulled back and forth, it drives the internal gear set to rotate, and amplifies the torque through the worm gear or planetary gear mechanism to achieve the lifting and lowering of heavy objects.

Self locking function: Using mechanical friction or ratchet structure, it automatically locks when stopping operation to prevent heavy objects from sliding down.

Q2. How to choose the rated load of the hand-operated hoist?

A: According to the actual load requirements, common specifications include 0.5T, 1T, 1.5T, 3T, 5T, etc.

Overloading is strictly prohibited, otherwise it may cause chain breakage or component damage.

Q3. What items need to be checked before use?

A: Chain/wire rope: Check for deformation, rust, or cracks.

Hook: Whether it is flexible, deformed or worn.

Braking device: Can it be reliably locked during no-load testing.

Handle: Whether the operation is smooth and there is no jamming.

Q4. How to choose the appropriate hand cranked hoist?

A: Load bearing requirement: Select a model with a rated load equal to or greater than the weight of the heavy object (with a safety factor of 1.5 times reserved).

Q5. Common faults and solutions

A: Difficulty in turning the handle: Clean and lubricate, adjust the chain position

Brake failure: replace worn parts, check spring elasticity

Chain/wire rope breakage: Stop immediately, replace with new parts, and investigate the cause of overload

Hook deformation: Replace the hook and check if the usage specifications are compliant
