Production Description
Spiral jack, also known as mechanical jack, is driven by human through screw pairs, with screw or nut sleeve as lifting parts. ordinary screw jack supports heavy objects by thread self-locking, which is simple in structure, but low in transmission efficiency and slow in return. The threads of the self-lowering screw jack have no self-locking effect and are equipped with brakes. Relax the brake, the weight can drop quickly by itself, shorten the return time, but the jack structure is more complex. Spiral jack can support heavy objects for a long time. Its maximum lifting weight has reached 100 tons, and it is widely used. When the horizontal screw is installed at the lower part, the weight can also be transversely moved at a small distance.
