Preventing heavy objects from shaking is the key to ensuring safe operation when using manual hoists (also known as chain hoists or hand cranked cranes) to lift heavy objects. Here are some effective methods to reduce or prevent heavy objects from shaking:

1. Ensure stable support

Ground selection: Choose a flat, sturdy, and stable ground for operation, avoiding use on slopes, soft, or uneven surfaces.

Leg deployment: If using a manual hoist with legs (such as a mobile or fixed lifting platform), make sure that the legs are fully deployed and firmly supported on the ground.

2. Proper hanging and fixing

Selection of suspension points: Choose sturdy and reliable suspension points to ensure that they can withstand the weight of heavy objects and maintain stability.

Selection of lifting equipment: Use lifting equipment that matches the weight and shape of the heavy object, such as hooks, slings, or chains, and ensure that they are installed correctly and securely without damage.

Balanced suspension: Ensure that the heavy object is balanced when lifted to avoid shaking caused by unbalanced load. If possible, use multiple lifting points to distribute weight and reduce shaking.

3. Smooth operation

Slow lifting: When lifting heavy objects, the operation should be smooth and slow to avoid sudden acceleration or deceleration causing shaking.

Control speed: Based on the weight and height of the heavy object, reasonably control the lifting speed of the manual hoist to ensure it is within a controllable range.

4. Use auxiliary equipment

Windproof rope: When working outdoors or in environments with strong winds, windproof ropes can be used to secure manual hoists and heavy objects, reducing shaking caused by wind.

Shock pad: Placing shock pads or soft cushions under heavy objects can reduce the impact and shaking of heavy objects when they fall to the ground to a certain extent.

5. Precautions for homework personnel

Standing safety: Operators should stand in a safe location and avoid standing under heavy objects or areas that may be affected by shaking.

Concentrate: Maintain a high level of concentration during the operation, constantly paying attention to the condition of heavy objects and changes in the surrounding environment.

6. Regular inspection and maintenance

Equipment inspection: Regularly inspect and maintain the manual hoist to ensure that it is in good working condition. Special attention should be paid to checking the wear and damage of key components such as lifting equipment, chains, and brakes.

Safety training: Provide safety training to operators on how to correctly use manual hoists, prevent and handle shaking and other safety issues.
