1.Rack and pinion design, stable functioning.
2.Double cylinder structure, double output could be achieved.
3.The manufacturing precision of working platform is high, and is easy for installation , and is of precise orientation.
4.The center of working platform has a through hole, and pipe can be located and passed through this hole;
5.Guide hole is designed on the both side of the cylinder body (10~200) or undersurface (2~7), which is simply to install.
6.Two modes of buffer could be chosen, adjustment bolt buffer and internal shock absorber, the maximum buffer energy of internal shock absorber is 3-5 times that of adjustment bolt buffer.
