The working principle of a screw jack is very different from that of a hydraulic jack. It is precisely because of this that a screw jack can be used horizontally, while a hydraulic jack can only be used vertically. However, when using a screw jack horizontally, one thing to pay attention to is the support point of the base.

We all know that the working principle of a screw jack is the interaction force between machines, and its load-bearing capacity is significantly greater than that of a hydraulic jack. Therefore, when used horizontally, a slight mistake can cause significant damage to the support points due to the reaction force.

So when using a screw jack for lateral operations, we must first carefully observe the state of the support point to see if its stability is greater than the target. If the stability or weight of the support point is lower than the target, not only will it not be able to push the target during the operation, but the force point will also move under the reverse force, which may cause danger.

So when using a screw jack for horizontal use, it is necessary to carefully observe the current situation and confirm the stability of the support points before proceeding with the operation.
