Under-body hydraulic cylinder series.

1.It can be used in a wider range of temperature and different working conditions in China, as well as exported to low temperature environment such as Russia and Ukraine, and high temperature environment such as Thailand, Middle East, etc.
2.The use of double piston sealing can substantially reduce the cylinder inner leakage, the lose of vehicle lifting force and the falling possibility of the carriage.
3.The use of lifting differential pressure anti-shake patented technology can ensure a smooth lifting of the carriage to the biggest angle and the use of descending buffering patented technology can maintain a reasonable range of impact when the carriage descends to the auxiliary girder.
