Why is it said that the handle of a screw jack should be pressed evenly? When lifting heavy objects with a jack, pressing the handle plays a role in lifting the jack. The force of the handle is moderate in order to evenly apply force to the jack. If the force is too high or too low, the following situation may occur.

1. The situation where the handle is pressed too hard does not mean that the heavy object can be lifted quickly. This method is incorrect because pressing too quickly will also cause excessive force, which is not only harmful to the jack, but also causes the lifting object to fall off if it malfunctions due to excessive force.

2. If you apply force too slowly, this method is not a way to save effort. Just like a saying, you won't feel tired when walking briskly, but when you slow down, you will feel tired. This is the downside of applying force too slowly and it won't help you save effort.

The benefits of evenly pressing the handle

1. It can effectively save your manual labor, apply even force without causing excessive damage to the machine, and it is the most labor-saving way for screw jacks.

2. It can ensure safety. Only with uniform lifting can objects avoid falling accidents caused by too fast or too slow.

Actually, regardless of your personality, whether it's chronic or acute, when using a screw jack, please follow the operating procedures. It's not your personality that determines the speed of your construction. I suggest you become a construction worker with good psychological resilience and a stable personality.
