When operating wire rope electric hoists, it is crucial to pay attention to not only the instructions provided in the manual but also to any abnormal phenomena that may arise outside of these instructions. Here are some key areas to watch out for:

Abnormal Sounds: If you hear any unusual or unexpected noises during operation, such as grinding, squealing, or rattling, this could indicate wear and tear, misalignment, or damage to the internal components of the hoist. Immediately stop using the hoist and inspect it thoroughly.

Excessive Vibrations: If the hoist vibrates excessively during operation, it may be due to unbalanced loads, improper maintenance, or worn-out bearings. Vibrations can lead to premature wear and tear on the hoist and may compromise its safety.

Unusual Heat Generation: If the hoist becomes unusually hot to the touch, it may be a sign of overloading, improper lubrication, or faulty electrical components. Overheating can damage the hoist and pose a risk of fire or electrical shock.

Slow or Uneven Lifting Speeds: If the lifting speed of the hoist becomes slow or uneven, it may be due to worn-out gears, belts, or bearings. This can affect the efficiency and reliability of the hoist and may require professional maintenance.

Changes in Load Handling: If the hoist struggles to lift or lower loads that it previously handled with ease, it may be a sign of weakening or damage to the wire rope, hooks, or other load-bearing components.

Electrical Issues: Any electrical problems, such as flickering lights, sparks, or unusual smells, should be investigated immediately. These can indicate issues with the hoist's wiring, motors, or controls.

Visual Damage: Regularly inspect the hoist for visible signs of damage, such as cracks, dents, or worn-out parts. Any damage should be addressed promptly to prevent further wear and tear and to ensure the safety of the hoist.
