Recently, it was reported in the news that a safety accident occurred in a certain city. At the scene of the accident, a repairman was pressed under the car because the jack was not fixed properly. After the efforts of several firefighters, the trapped person was successfully rescued.

This incident made us understand that even experienced people cannot 100% deliver their safety to a mechanical equipment. And the proper operation of the jack is also a big chip to ensure our life safety.

When using a jack, it is important to ensure the stability of the jack base, as uneven ground can easily cause the jack to stand unsteadily. At this point, it is necessary to use sleepers or steel plates to help stabilize the base of the jack, which is the prerequisite for safe operation.

So before using a jack for work, everyone must eliminate all hidden dangers in order to keep safety in their hands.
