Product Feature
		
		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.
