Working principle of mechanical screw jack

Answer:

Jack by the manpower through the screw drive, screw or nut sleeve as the top lift, jack screw thread self-locking action on the support, to avoid severe vibration should be top jack jack jack users to use process, according to the use of regular inspection and maintenance is made of high quality alloy steel material, more durable than similar products, as a commonly used lifting tool, Baoshan screw jack is a good helper to improve work efficiency. In the use of Jack, if only one, then be sure to select the weight of the center of gravity, and then point to the center of the jack, so as to prevent the lifting process in the tilt, resulting in accidents.
The screw jack can support heavy load for a long time, the maximum lifting capacity has reached 100 tons, and it is widely used. When the lower part is loaded with a horizontal screw rod, the heavy object can be moved at a small distance.
Screw jack, also known as mechanical jack, is driven by the screw through the screw, screw or nut sleeve as a lifting device. Ordinary screw jack by thread self-locking function support heavy, simple structure, but the transmission efficiency is low, return slow. The self - lowering screw jack has no self-locking function and is equipped with a brake. When the brake is relaxed, the weight can fall rapidly and shorten the return time, but the jack structure is complicated.
