Hydraulic automatic oiling controller of jack system is used for automatic control of bridge prestress tensioning. It uses a highly integrated controller to control two-cylinder or four-cylinder synchronous tensioning through solenoid valves. The system is simple to operate, one-key operation can complete the entire tensioning process, with high control accuracy, which can effectively improve the quality of prestress construction.

Feathers：
Support a variety of Post-Tensioning modes, including Single Beam Single End tensioning, Dual Beam Single End tensioning,
TripleBeam Single End tensioning, Quad Beam Single End tensioning, Single Beam Both Ends tensioning and Dual Beam Both Ends
tensioning.
Support Pre-Tensioning with two synchronous cylinders.
Support Full Automatic Operation and Step by Step Operation.
The displacement sensor signal is transmitted digitally to keep away from interference.
Any one of the two sets of the controller can be set up as host or slave, Both can work separately in Single Beam Single
Endtension mode .
Record data can be exported by USB or uploaded to the server through the Internet.
