Spiral jack is a type of mechanical jack. When the operator rotates the handle, the lifting sleeve of the jack will drive the heavy object to rise or fall together. During the lifting process, we can observe that the position of the heavy object is gradually rising, falling, or moving in the left and right directions. However, the effect of lifting different heavy objects varies in different situations and fields.
