Methods and conditions for parallel use of hydraulic jacks

The methods and conditions of parallel use of hydraulic jacks were analyzed and evaluated. The same specifications and different specifications of jacks were discussed. The correct methods and related conditions of parallel use of hydraulic jacks were clarified. The error between the calibration value and the regression value of the corresponding points of the regression equation was analyzed, and the error between the calibration value and the regression value of the parallel regression equation was analyzed and discussed. The results show that under certain conditions, the error of parallel use of hydraulic jacks could be controlled within a certain range, and it had obvious optimization effect.
