As the load-bearing capacity of the screw jack gradually increases, the overall size of the jack, from the intricate internal structure to the top cover and the control handle, will correspondingly increase. However, due to the design limitations of the jack itself, no matter how much weight it can carry, compared to the huge area of the weight, the area of the anti slip top cover of the jack always appears particularly small. If such a compact anti slip top cover is used to lift a large area of heavy objects, it will undoubtedly bury many safety hazards.

To effectively avoid these potential risks, it is important to pay attention to the following key points when using a jack to lift heavy objects:

1、 Be sure to ensure that the center of the anti slip cover of the jack is precisely on the same vertical line as the center of gravity of the heavy object and the center point of the supporting ground. In this way, it can avoid dangerous situations such as sudden sliding of heavy objects and accidental collapse of jacks caused by uneven force during the lifting process.

2、 If the area of the heavy object is really too large, it may be considered to use two jacks to work together at the same time. However, during this process, the operator must maintain a synchronized and consistent lifting speed under the unified command of professional personnel to ensure a smooth and orderly lifting process.

3、 When the area of the heavy object is too large and the screw jack is no longer sufficient to complete the lifting task, we strongly recommend that customers change their mindset and choose other types of lifting tools, such as hoists, gantry cranes, cantilever cranes, or truck cranes, to ensure the safety and efficiency of the operation.
