Working Principle:

 Under the function of oil presurre,the moving part moves relative to the fixed part to realize tensioning the jack.The design tensioning force can be obtained by controlling the area of the tensioning cavity and the oil pressure.In order to reduce the weight of the jack,the stroke of the jack is designed as 120mm,160mm and 200mm.the front-jaming jack has the performance of  continuously progressive repeated tensioning,and it can realize the tensioning of prestressing tendons of different lengths.The structure diagram of the YDQ front-jaming jack is shown in the figure below:
