Jack is a precision lifting equipment, which has a high utilization rate in our life and production. From the repair of private cars to the construction of bridges, jacks are indispensable. But the jack can't guarantee our 100% safety.

When using the jack, be sure to ensure the stability of the jack base. The pit ground is easy to make the jack stand unstable. At this time, it is necessary to help with the bedding of sleepers or steel plates to stabilize the base of the jack, which is the premise of safe operation.

Therefore, we must eliminate all hidden dangers before using the jack for operation, so as to control the safety in our own hands.
