The device is made up of: Hydraulic cylinder as an execution unit; A self-propelled hydraulic device is provided with a skidding system, which can not only solve the stability problem of conventional pushing during traction cylinders’ operation, but also it can overcome the unevenness and nonlinearity of the skidding track, as well as the uneven settlement issue in the translation process.

During the process, lifting cylinder vertically jacks up the upper load and continues jacking, at this stage, the pushing cylinders shall be put into action, once pushing movement starts, the main jacking mechanism is set to skid on the designed skidding surface as a whole under the thrust of the pushing cylinder, the skidding distance will depend on the jacking length of the pushing cylinder, when it jacks to the right position in one time jacking, another group of self-propelled hydraulic devices join in the work, carry out the transfer of load force, and then carry out the pushing of the next round, and carry out the reset operation to the previous group of self-propelled hydraulic devices in the pushing process, preparing to repeat next cycle of the same action.
