What is the primary function of a jack in construction?

The primary function of a jack in construction is to raise heavy objects. Jacks are mechanical devices that utilize either hydraulic, mechanical, or pneumatic means to lift loads safely and efficiently. They are essential for tasks such as lifting beams, vehicles, and other heavy materials to facilitate assembly, installation, or repairs.

Using a jack allows workers to perform these tasks with greater safety and control, minimizing the risk of accidents associated with lifting heavy loads manually. This capability makes jacks a vital tool in construction, where handling heavy materials is a common requirement.
