A summary of common malfunctions of low clean empty hand pulling gourds (presumably referring to hand-operated lifting devices or chain blocks, given the context) can include several key points. These devices are often used in various industrial settings for lifting and moving loads. However, they can suffer from various malfunctions due to wear and tear, improper use, or manufacturing defects. Here are some common malfunctions:

Chain Malfunctions:

Wear and Tear: The chains may wear out over time, leading to reduced strength and increased risk of failure.

Stuck Links: Chains may become stuck or jammed due to debris, rust, or improper lubrication.

Hook Malfunctions:

Wear and Deformation: Hooks may wear out or deform over time, reducing their ability to securely hold loads.

Cracking and Fracturing: Hooks may crack or fracture due to overloading or improper use.

Gearbox Malfunctions:

Gear Wear: Gears within the gearbox may wear out, leading to reduced efficiency and increased noise.

Oil Leaks: Leaks in the gearbox oil seals can lead to loss of lubrication and increased wear on gears.

Brake Malfunctions:

Wear and Adjustment Issues: Brakes may wear out or become improperly adjusted, reducing their effectiveness in stopping the load.

Contamination: Brakes may become contaminated with debris or moisture, affecting their performance.

Handle Malfunctions:

Wear and Slippage: Handles may wear out or become slippery, reducing the operator's ability to control the device.

Breakage: Handles may break due to overloading or improper use.

Structural Malfunctions:

Cracking and Fracturing: The structural components of the device may crack or fracture due to overloading, improper use, or manufacturing defects.

Weld Failures: Welds may fail, leading to separation of structural components.

Electrical Malfunctions (if applicable):

Circuit Failures: Electrical circuits may fail, affecting the device's operation.

Motor Malfunctions: Motors may suffer from wear and tear, leading to reduced performance or failure.
