从理论上讲，千斤顶的顶力可以任意进步，从而也能达到任意长度的推顶间隔。
Theoretically, the jacking force can be enhanced arbitrarily, so the jacking distance can reach arbitrary length.
推移千斤顶采用框架结构，以减少推溜力和增大移架力。
Passes the hoisting jack to use the portal frame construction, reduces pushes slides the strength and increases moves a strength.
