The screw jack is driven by human power through the screw pair, and the screw rod or nut sleeve serves as the lifting part. Ordinary screw jacks support weight by thread self-locking function, simple structure, but low transmission efficiency, slow return.

    The screw thread of the auger jack has no self locking function and is equipped with brake. When the brake is relaxed, the weight can fall quickly and shorten the return trip. The screw jack can support heavy weight for a long time, and the maximum lifting weight has reached 100 tons, which is widely used. After the lower part is fitted with the horizontal screw, the weight can be moved across a small distance
