Spiral jack is a commonly used mechanical lifting tool, which is widely used in fields such as vehicle maintenance and equipment installation due to its simple structure, strong load-bearing capacity, and high reliability. When the workspace is limited and cannot be placed vertically, horizontal use becomes a solution for special working conditions, but technical specifications must be strictly followed to ensure safety.

The original intention of the design of the screw jack is vertical force, and when used horizontally, three key points need to be evaluated: first, the threaded engagement surface between the screw and the base needs to maintain uniform force to avoid unilateral wear; Secondly, the base must be equipped with anti slip positioning structure to prevent lateral sliding; Thirdly, the center of gravity of the load needs to coincide with the axis of the jack, as eccentric loads can cause the threads to get stuck or even break.

The lateral use of a screw jack is a technical flexibility under specific conditions, and risk control must be achieved through force analysis, working condition evaluation, and protection upgrades.
