At present, the jack has a very high utilization rate, especially in vehicle maintenance. Although the jack has a solid base and strong load capacity, we still need to pay attention to and standardize the operation in the process of use.

Not long ago, there was a news report that a safety accident occurred in a city. A repairman at the scene of the accident was pressed to the bottom of the car because the jack was not fixed properly. After the efforts of several firefighters, the trapped people were successfully rescued. This event makes us understand that no experienced person can deliver his own safety to a mechanical equipment. And the normal operation of the jack is also a big chip to ensure our life safety.

The stability of the jack base must be ensured when using the jack, and the jack is easy to stand unsteadily on the pitted ground. At this time, it is necessary to use sleeper or steel plate to help stabilize the base of the jack, which is the basic prerequisite for safe use of the jack.
